Microorganisms for succinic acid production

This application is a National Stage application of International Application No. PCT/EP2015/052048, filed Feb. 2, 2015, which claims priority under 35 U.S.C. § 119 to European Patent Application Nos. 14154302.5, filed Feb. 7, 2014 and 14176517.2, filed Jul. 10, 2014.

This application incorporates by reference in its entirety a computer-readable nucleotide/amino acid sequence listing identified as one 135,309 byte ASCII (text) file named “H75273_SubSeqListing.txt,” created Jul. 27, 2016.

The present invention relates to a modified microorganism, to a method for producing organic compounds and to the use of modified microorganisms.

Organic compounds such as small dicarboxylic acids having 6 or fewer carbons are commercially significant chemicals with many uses. For example, the small diacids include 1,4-diacids, such as succinic acid, malic acid and tartaric acid, and the 5-carbon molecule itaconic acid. Other diacids include the two carbon oxalic acid, three carbon malonic acid, five carbon glutaric acid and the 6 carbon adipic acid and there are many derivatives of such diacids as well.

As a group the small diacids have some chemical similarity and their uses in polymer production can provide specialized properties to the resin. Such versatility enables them to fit into the downstream chemical infrastructure markets easily. For example, the 1,4-diacid molecules fulfill many of the uses of the large scale chemical maleic anhydride in that they are converted to a variety of industrial chemicals (tetrahydrofuran, butyrolactone, 1,4-butanediol, 2-pyrrolidone) and the succinate derivatives succindiamide, succinonitrile, diaminobutane and esters of succinate. Tartaric acid has a number of uses in the food, leather, metal and printing industries. Itaconic acid forms the starting material for production of 3-methylpyrrolidone, methyl-BDO, methyl-THF and others.

In particular, succinic acid or succinate—these terms are used interchangeably herein—has drawn considerable interest because it has been used as a precursor of many industrially important chemicals in the food, chemical and pharmaceutical industries. In fact, a report from the U.S. Department of Energy reports that succinic acid is one of 12 top chemical building blocks manufactured from biomass. Thus, the ability to make diacids in bacteria would be of significant commercial importance.

WO-A-2009/024294 discloses a succinic acid producing bacterial strain, being a member of the family of Pasteurellaceae, originally isolated from rumen, and capable of utilizing glycerol as a carbon source and variant and mutant strains derived there from retaining said capability, in particular, a bacterial strain designated DD1 as deposited with DSMZ (Deutsche Sammlung von Mikroorganismen and Zellkulturen GmbH, Inhoffenstr. 7B, D-38124 Braunschweig, Germany) having the deposit number DSM 18541 (ID 06-614) and having the ability to produce succinic acid. The DD1-strain belongs to the species Basfia succiniciproducens and the family of Pasteurellaceae as classified by Kuhnert et al., 2010. Mutations of these strains, in which the IdhA-gene and/or the pfID- or the pfIA-gene have been disrupted, are disclosed in WO-A2010/092155, these mutant strains being characterized by a significantly increased production of succinic acid from carbon sources such as glycerol or mixtures of glycerol and carbohydrates such as maltose, under anaerobic conditions compared to the DD1-wild-type disclosed in WO-A-2009/024294.

However, when using bacterial strains such as those disclosed in WO-A-2009/024294 or WO-A2010/092155 for the production or organic compounds such as succinic acid, the selectivity in which the carbon sources are converted into the desired organic compounds and also the yield of the desired organic compound is still improvable.

Furthermore, it has been observed that when using the bacterial strains of the prior art for the production of organic compounds such as succinic acid under anaerobic conditions, the growth rate of the microorganisms is also improvable in order to make the microorganisms more suitable for the production of organic compounds such as succinic acid in an industrial scale.

It was therefore an object of the present invention to overcome the disadvantages of the prior art.

In particular, it was an object of the present invention to provide microorganisms which can be used for the fermentative production of organic compounds such as succinic acid and which not only produce the desired organic products, such as succinic acid, from assimilable carbon sources such as glycerol, glucose, sucrose, xylose, lactose, fructose or maltose in large amounts, preferably with only low amounts of side products, but which are also characterized by a fast growth under anaerobic conditions.

A contribution to achieving the abovementioned aims is provided by a modified microorganism having, compared to its wild-type, a reduced activity of the enzyme that is encoded by the pykA-gene, wherein the wild-type from which the modified microorganism has been derived belongs to the family of Pasteurellaceae. A contribution to achieving the above mentioned aims is in particular provided by a modified microorganism in which mutations have been introduced into the wild-type pykA-gene, wherein the wild-type from which the modified microorganism has been derived belongs to the family of Pasteurellaceae.

Surprisingly, it has been discovered that a reduction of the activity of the enzyme that is encoded by the pykA-gene (this enzyme PykA is a pyruvate kinase catalyzing the conversion of phosphoenolpyruvate (PEP) to pyruvate (EC 2.7.1.40)), preferably by introducing at least one mutation into the wild-type-pykA-gene, results in a recombinant Pasteurellaceae-strain that, compared to the corresponding microorganism in which the activity of this enzyme has not been decreased, is characterized by an increased yield of organic compounds such as succinic acid and also by a faster growth under anaerobic conditions.

In context with the expression “a modified microorganism having, compared to its wild-type, a reduced activity of the enzyme that is encoded by the x-gene”, wherein the x-gene is the pykA-gene and optionally, as described later, the IdhA-gene, the pfIA-gene and/or the pfID-gene, the term “wild-type” refers to a microorganism in which the activity of the enzyme that is encoded by the x-gene has not been decreased, i. e. to a microorganism whose genome is present in a state as before the introduction of a genetic modification of the x-gene (in particular of the pykA-gene and optionally the IdhA-gene, the pfIA-gene and/or the pfID-gene). Preferably, the expression “wild-type” refers to a microorganism whose genome, in particular whose x-gene, is present in a state as generated naturally as the result of evolution. The term may be used both for the entire microorganism but preferably for individual genes, e.g. the pykA-gene, the IdhA-gene, the pfIA-gene and/or the pfID-gene. The term “modified microorganism” thus includes a microorganism which has been genetically altered, modified or engineered (e.g., genetically engineered) such that it exhibits an altered, modified or different genotype and/or phenotype (e. g., when the genetic modification affects coding nucleic acid sequences of the microorganism) as compared to the naturally-occurring wild-type microorganism from which it was derived. According to a particular preferred embodiment of the modified microorganism according to the present invention the modified microorganism is a recombinant microorganism, which means that the microorganism has been obtained using recombinant DNA. The expression “recombinant DNA” as used herein refers to DNA sequences that result from the use of laboratory methods (molecular cloning) to bring together genetic material from multiple sources, creating sequences that would not otherwise be found in biological organisms. An example of such a recombinant DNA is a plasmid into which a heterologous DNA-sequence has been inserted.

The wild-type from which the microorganisms according to the present invention are derived belongs to the family of Pasteurellaceae. Pasteurellaceae comprise a large family of Gramnegative Proteobacteria with members ranging from bacteria such as Haemophilus influenzae to commensals of the animal and human mucosa. Most members live as commensals on mucosal surfaces of birds and mammals, especially in the upper respiratory tract. Pasteurellaceae are typically rod-shaped, and are a notable group of facultative anaerobes. They can be distinguished from the related Enterobacteriaceae by the presence of oxidase, and from most other similar bacteria by the absence of flagella. Bacteria in the family Pasteurellaceae have been classified into a number of genera based on metabolic properties and their sequences of the 16S RNA and 23S RNA. Many of the Pasteurellaceae contain pyruvate-formate-lyase genes and are capable of anaerobically fermenting carbon sources to organic acids.

According to a particular preferred embodiment of the modified microorganism according to the present invention the wild-type from which the modified microorganism has been derived belongs to the genus Basfia and it is particularly preferred that the wild-type from which the modified microorganism has been derived belongs to the species Basfia succiniciproducens.

Most preferably, the wild-type from which the modified microorganism according to the present invention as been derived is Basfia succiniciproducens -strain DD1 deposited on Aug. 11, 2006 under the Budapest Treaty with DSMZ (Deutsche Sammlung von Mikroorganismen and Zellkulturen, GmbH), Germany, having the deposit number DSM 18541. This strain has been originally isolated from the rumen of a cow of German origin. Pasteurella bacteria can be isolated from the gastrointestinal tract of animals and, preferably, mammals. The bacterial strain DD1, in particular, can be isolated from bovine rumen and is capable of utilizing glycerol (including crude glycerol) as a carbon source. Further strains of the genus Basfia that can be used for preparing the modified microorganism according to the present invention are the Basfia -strain that has been deposited under the deposit number DSM 22022 with DSZM or the Basfia -strains that have been deposited with the Culture Collection of the University of Goteborg (CCUG), Sweden, having the deposit numbers CCUG 57335, CCUG 57762, CCUG 57763, CCUG 57764, CCUG 57765 or CCUG 57766. Said strains have been originally isolated from the rumen of cows of German or Swiss origin.

In this context it is particularly preferred that the wild-type from which the modified microorganism according to the present invention has been derived has a 16S rDNA of SEQ ID NO: 1 or a sequence, which shows a sequence homology of at least 96%, at least 97%, at least 98%, at least 99% or at least 99.9% with SEQ ID NO: 1. It is also preferred that the wild-type from which the modified microorganism according to the present invention has been derived has a 23S rDNA of SEQ ID NO: 2 or a sequence, which shows a sequence homology of at least 96%, at least 97%, at least 98%, at least 99% or at least 99.9% with SEQ ID NO: 2.

The identity in percentage values referred to in connection with the various polypeptides or polynucleotides to be used for the modified microorganism according to the present invention is, preferably, calculated as identity of the residues over the complete length of the aligned sequences, such as, for example, the identity calculated (for rather similar sequences) with the aid of the program needle from the bioinformatics software package EMBOSS (Version 5.0.0, http://emboss.source-forge.net/what/) with the default parameters which are, i.e. gap open (penalty to open a gap): 10.0, gap extend (penalty to extend a gap): 0.5, and data file (scoring matrix file included in package): EDNAFUL.

It should be noted that the modified microorganism according to the present invention can not only be derived from the above mentioned wild-type-microorganisms, especially from Basfia succiniciproducens -strain DD1, but also from variants of these strains. In this context the expression “a variant of a strain” comprises every strain having the same or essentially the same characteristics as the wild-type-strain. In this context it is particularly preferred that the 16 S rDNA of the variant has an identity of at least 90%, preferably at least 95%, more preferably at least 99%, more preferably at least 99.5%, more preferably at least 99.6%, more preferably at least 99.7%, more preferably at least 99.8% and most preferably at least 99.9% with the wild-type from which the variant has been derived. It is also particularly preferred that the 23 S rDNA of the variant has an identity of at least 90%, preferably at least 95%, more preferably at least 99%, more preferably at least 99.5%, more preferably at least 99.6%, more preferably at least 99.7%, more preferably at least 99.8% and most preferably at least 99.9% with the wild-type from which the variant has been derived. A variant of a strain in the sense of this definition can, for example, be obtained by treating the wild-type-strain with a mutagenizing chemical agent, X-rays, or UV light.

The modified microorganism according to the present invention is characterized in that, compared to its wild-type, the activity of the enzyme that is encoded by the pykA-gene is reduced.

The reduction of the enzyme activity (Δ activity ) is preferably defined as follows:

Δ activity = 100 ⁢ % - ( activity ⁢ ⁢ of ⁢ ⁢ the ⁢ ⁢ modified ⁢ ⁢ microorganism activity ⁢ ⁢ of ⁢ ⁢ the ⁢ ⁢ wildtype × 100 ⁢ % )

wherein, when determining Δ activity , the activity in the wild-type and the activity in the modified microorganism are determined under exactly the same conditions. Methods for the detection and determination of the activity of the enzyme that is encoded by the pykA-gene can be found, for example, in Bergmeyer, H. U., Gawehn, K., and Grassi, M. (1974): “ Methods of Enzymatic Analysis ”, Second Edition, Volume I, pages 509-511, Academic Press, Inc., New York, N.Y.

The reduced activity of the enzymes disclosed herein, in particular the reduced activity of the enzyme encoded by the pykA-gene, the lactate dehydrogenase and/or the pyruvate formate lyase, can be a reduction of the enzymatic activity by 0.1 to 99%, compared to the activity of said enzyme in the wild-type of the microorganism, or a reduction of the enzymatic activity by at least 15%, or at least 25%, or at least 35%, or at least 45%, or at least 55%, or at least 65%, or at least 75% or at least 85%, or at least 86%, or at least 87%, or at least 88%, or at least 89%, or at least 90%, or at least 91%, or at least 92%, or at least 93%, or at least 94%, or at least 95%, or at least 96%, or at least 97%, or at least 98%, or at least 99%. Preferably, the reduction of the activity of the enzyme encoded by the pykA-gene is in the range of 15 to 99%, more preferably in the range of 50 to 95% and even more preferably in the range of 90 to 99%. The term “reduced activity of the enzyme that is encoded by the pykA-gene” or—as described below—“a reduced lactate dehydrogenase activity” or “a reduced pyruvate formate lyase activity”, also encompasses a modified microorganism which has no detectable activity of these enzymes.

The term “reduced activity of an enzyme” includes, for example, the expression of the enzyme by said genetically modified (e.g., genetically engineered) microorganism at a lower level than that expressed by the wild-type of said microorganism. Genetic manipulations for reducing the expression of an enzyme can include, but are not limited to, deleting the gene or parts thereof encoding for the enzyme, altering or modifying regulatory sequences or sites associated with expression of the gene encoding the enzyme (e.g., by removing strong promoters or repressible promoters), modifying proteins (e.g., regulatory proteins, suppressors, enhancers, transcriptional activators and the like) involved in transcription of the gene encoding the enzyme and/or the translation of the gene product, or any other conventional means of decreasing expression of a particular gene routine in the art (including, but not limited to, the use of antisense nucleic acid molecules or other methods to knock-out or block expression of the target protein). Further on, one may introduce destabilizing elements into the mRNA or introduce genetic modifications leading to deterioration of ribosomal binding sites (RBS) of the RNA. It is also possible to change the codon usage of the gene in a way, that the translation efficiency and speed is decreased.

A reduced activity of an enzyme can also be obtained by introducing one or more gene mutations which lead to a reduced activity of the enzyme. Furthermore, a reduction of the activity of an enzyme may also include an inactivation (or the reduced expression) of activating enzymes which are necessary in order to activate the enzyme the activity of which is to be reduced. By the latter approach the enzyme the activity of which is to be reduced is preferably kept in an inactivated state.

Microorganisms having a reduced activity of the enzyme encoded by the pykA-gene may occur naturally, i.e. due to spontaneous mutations. A microorganism can be modified to lack or to have significantly reduced activity of the enzyme that is encoded by the pykA-gene by various techniques, such as chemical treatment or radiation. To this end, microorganisms will be treated by, e.g., a mutagenizing chemical agent, X-rays, or UV light. In a subsequent step, those microorganisms which have a reduced activity of the enzyme that is encoded by the pykA-gene will be selected. Modified microorganisms are also obtainable by homologous recombination techniques which aim to mutate, disrupt or excise the pykA-gene in the genome of the microorganism or to substitute the gene with a corresponding gene that encodes for an enzyme which, compared to the enzyme encoded by the wild-type-gene, has a reduced activity.

According to a preferred embodiment of the modified microorganism according to the present invention, the activity of the enzyme encoded by the pykA-gene is reduced by introducing at least one mutation into the pykA-gene, preferably into the wild-type-pykA-gene. In this context it is particularly preferred that the at least one mutation leads to a modification of the nucleic acid sequence of the pykA-gene, such that the amino acid sequence of the enzyme encoded by the modified gene differs from the amino acid sequence of the enzyme encoded by the wild-type pykA-gene in at least one amino acid.

A mutation into the pykA-gene can be introduced, for example, by site-directed or random mutagenesis, followed by an introduction of the modified gene into the genome of the microorganism by recombination. Variants of the pykA-gene can be are generated by mutating the gene sequence SEQ ID NO: 3 by means of PCR. The “Quickchange Site-directed Mutagenesis Kit” (Stratagene) can be used to carry out a directed mutagenesis. A random mutagenesis over the entire coding sequence, or else only part thereof, of SEQ ID NO: 3 can be performed with the aid of the “GeneMorph II Random Mutagenesis Kit” (Stratagene). The mutagenesis rate is set to the desired amount of mutations via the amount of the template DNA used. Multiple mutations are generated by the targeted combination of individual mutations or by the sequential performance of several mutagenesis cycles.

In the following, a suitable technique for recombination, in particular for introducing the modified pykA-gene into the microorgansim, is described.

This technique is also sometimes referred to as the “Campbell recombination” herein (Leenhouts et al., Appl Env Microbiol . (1989), Vol. 55, pages 394-400). “Campbell in”, as used herein, refers to a transformant of an original host cell in which an entire circular double stranded DNA molecule (for example a plasmid) has integrated into a chromosome by a single homologous recombination event (a cross in event), and that effectively results in the insertion of a linearized version of said circular DNA molecule into a first DNA sequence of the chromosome that is homologous to a first DNA sequence of the said circular DNA molecule. “Campbelled in” refers to the linearized DNA sequence that has been integrated into the chromosome of a “Campbell in” transformant. A “Campbell in” contains a duplication of the first homologous DNA sequence, each copy of which includes and surrounds a copy of the homologous recombination crossover point.

“Campbell out”, as used herein, refers to a cell descending from a “Campbell in” transformant, in which a second homologous recombination event (a cross out event) has occurred between a second DNA sequence that is contained on the linearized inserted DNA of the “Campbelled in” DNA, and a second DNA sequence of chromosomal origin, which is homologous to the second DNA sequence of said linearized insert, the second recombination event resulting in the deletion (jettisoning) of a portion of the integrated DNA sequence, but, importantly, also resulting in a portion (this can be as little as a single base) of the integrated Campbelled in DNA remaining in the chromosome, such that compared to the original host cell, the “Campbell out” cell contains one or more intentional changes in the chromosome (for example, a single base substitution, multiple base substitutions, insertion of a heterologous gene or DNA sequence, insertion of an additional copy or copies of a homologous gene or a modified homologous gene, or insertion of a DNA sequence comprising more than one of these aforementioned examples listed above). A “Campbell out” cell is, preferably, obtained by a counter-selection against a gene that is contained in a portion (the portion that is desired to be jettisoned) of the “Campbelled in” DNA sequence, for example the Bacillus subtilis sacB-gene, which is lethal when expressed in a cell that is grown in the presence of about 5% to 10% sucrose. Either with or without a counter-selection, a desired “Campbell out” cell can be obtained or identified by screening for the desired cell, using any screenable phenotype, such as, but not limited to, colony morphology, colony color, presence or absence of antibiotic resistance, presence or absence of a given DNA sequence by polymerase chain reaction, presence or absence of an auxotrophy, presence or absence of an enzyme, colony nucleic acid hybridization, antibody screening, etc. The term “Campbell in” and “Campbell out” can also be used as verbs in various tenses to refer to the method or process described above.

It is understood that the homologous recombination events that leads to a “Campbell in” or “Campbell out” can occur over a range of DNA bases within the homologous DNA sequence, and since the homologous sequences will be identical to each other for at least part of this range, it is not usually possible to specify exactly where the crossover event occurred. In other words, it is not possible to specify precisely which sequence was originally from the inserted DNA, and which was originally from the chromosomal DNA. Moreover, the first homologous DNA sequence and the second homologous DNA sequence are usually separated by a region of partial non-homology, and it is this region of non-homology that remains deposited in a chromosome of the “Campbell out” cell.

Preferably, first and second homologous DNA sequence are at least about 200 base pairs in length, and can be up to several thousand base pairs in length. However, the procedure can be made to work with shorter or longer sequences. For example, a length for the first and second homologous sequences can range from about 500 to 2000 bases, and the obtaining of a “Campbell out” from a “Campbell in” is facilitated by arranging the first and second homologous sequences to be approximately the same length, preferably with a difference of less than 200 base pairs and most preferably with the shorter of the two being at least 70% of the length of the longer in base pairs.

The pykA-gene the activity of which is reduced in the modified microorganism according to the present invention preferably comprises a nucleic acid selected from the group consisting of:

a) nucleic acids having the nucleotide sequence of SEQ ID NO: 3; b) nucleic acids encoding the amino acid sequence of SEQ ID NO: 4; c) nucleic acids which are at least 70%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, at least 99.5%, at least 99.6%, at least 99.7%, at least 99.8% or at least 99.9%, most preferably 100% identical to the nucleic acid of a) or b), the identity being the identity over the total length of the nucleic acids of a) or b); d) nucleic acids encoding an amino acid sequence which is at least 70%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, at least 99.5%, at least 99.6%, at least 99.7%, at least 99.8% or at least 99.9%, most preferably 100% identical to the amino acid sequence encoded by the nucleic acid of a) or b), the identity being the identity over the total length of amino acid sequence encoded by the nucleic acids of a) or b); e) nucleic acids capable of hybridizing under stringent conditions with a complementary sequence of any of the nucleic acids according to a) or b); and f) nucleic acids encoding the same protein as any of the nucleic acids of a) or b), but differing from the nucleic acids of a) or b) above due to the degeneracy of the genetic code.

The term “hybridization” as used herein includes “any process by which a strand of nucleic acid molecule joins with a complementary strand through base pairing” (J. Coombs (1994) Dictionary of Biotechnology, Stockton Press, New York). Hybridization and the strength of hybridization (i.e., the strength of the association between the nucleic acid molecules) is impacted by such factors as the degree of complementarity between the nucleic acid molecules, stringency of the conditions involved, the Tm of the formed hybrid, and the G:C ratio within the nucleic acid molecules.

As used herein, the term “Tm” is used in reference to the “melting temperature”. The melting temperature is the temperature at which a population of double-stranded nucleic acid molecules becomes half dissociated into single strands. The equation for calculating the Tm of nucleic acid molecules is well known in the art. As indicated by standard references, a simple estimate of the Tm value may be calculated by the equation: Tm=81.5+0.41(% G+C), when a nucleic acid molecule is in aqueous solution at 1 M NaCl (see e.g., Anderson and Young, Quantitative Filter Hybridization, in Nucleic Acid Hybridization (1985)). Other references include more sophisticated computations, which take structural as well as sequence characteristics into account for the calculation of Tm. Stringent conditions, are known to those skilled in the art and can be found in Current Protocols in Molecular Biology, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6.

In particular, the term “stringency conditions” refers to conditions, wherein 100 contiguous nucleotides or more, 150 contiguous nucleotides or more, 200 contiguous nucleotides or more or 250 contiguous nucleotides or more which are a fragment or identical to the complementary nucleic acid molecule (DNA, RNA, ssDNA or ssRNA) hybridizes under conditions equivalent to hybridization in 7% sodium dodecyl sulfate (SDS), 0.5 M NaPO4, 1 mM EDTA at 50° C. with washing in 2×SSC, 0.1% SDS at 50° C. or 65° C., preferably at 65° C., with a specific nucleic acid molecule (DNA; RNA, ssDNA or ss RNA). Preferably, the hybridizing conditions are equivalent to hybridization in 7% sodium dodecyl sulfate (SDS), 0.5 M NaPO4, 1 mM EDTA at 50° C. with washing in 1×SSC, 0.1% SDS at 50° C. or 65° C., preferably 65° C., more preferably the hybridizing conditions are equivalent to hybridization in 7% sodium dodecyl sulfate (SDS), 0.5 M NaPO4, 1 mM EDTA at 50° C. with washing in 0.1×SSC, 0.1% SDS at 50° C. or 65° C., preferably 65° C. Preferably, the complementary nucleotides hybridize with a fragment or the whole pykA nucleic acids. Alternatively, preferred hybridization conditions encompass hybridization at 65° C. in 1×SSC or at 42° C. in 1×SSC and 50% formamide, followed by washing at 65° C. in 0.3×SSC or hybridization at 50° C. in 4×SSC or at 40° C. in 6×SSC and 50% formamide, followed by washing at 50° C. in 2×SSC. Further preferred hybridization conditions are 0.1% SDS, 0.1 SSD and 65° C.

The pykA-gene in which at last one mutation is introduced by the above mentioned combination of side-directed mutagenesis and “Campbell recombination” preferably comprises a nucleic acid as defined above.

Nucleic acid having the nucleotide sequence of SEQ ID NO: 3 corresponds to the pykA-gene of Basfia succiniciproducens -strain DD1.

According to a preferred embodiment of the modified microorganism according to the present invention, the modified microorganism does not have, compared to its wild-type, an increased level of the activity of phosphoenol pyruvate carboxykinase (EC 4.1.1.49), which is encoded by the pcK-gene. In this context it is particularly preferred that in the modified microorganism the level of the of phosphoenol pyruvate carboxykinase activity is not increased as a result from the replacement of native regulatory sequences of the pck-gene with altered regulatory sequences that increases phosphoenol pyruvate carboxykinase activity.

According to a further preferred embodiment of the modified microorganism according to the present invention, this microorganism is not only characterized by a reduced activity of the enzyme encoded by the pykA-gene, but also, compared to its wild-type, by

i) a reduced pyruvate formate lyase activity, ii) a reduced lactate dehydrogenase activity, or iii) a reduced pyruvate formate lyase activity and a reduced lactate dehydrogenase activity.

Modified microorganisms being deficient in lactate dehydrogenase and/or being deficient in pyruvate formate lyase activity are disclosed in WO-A-2010/092155, US 2010/0159543 and WO-A-2005/052135, the disclosure of which with respect to the different approaches of reducing the activity of lactate dehydrogenase and/or pyruvate formate lyase in a microorganism, preferably in a bacterial cell of the genus Pasteurella , particular preferred in Basfia succiniciproducens strain DD1, is incorporated herein by reference. Methods for determining the pyruvate formate lyase activity are, for example, disclosed by Asanuma N. and Hino T. in “ Effects of pH and Energy Supply on Activity and Amount of Pyruvate - Formate - Lyase in Streptococcus bovis ”, Appl. Environ. Microbiol. (2000), Vol. 66, pages 3773-3777″ and methods for determining the lactate dehydrogenase activity are, for example, disclosed by Bergmeyer, H. U., Bergmeyer J. and Grassi, M. (1983-1986) in “ Methods of Enzymatic Analysis ”, 3 rd Edition, Volume III, pages 126-133, Verlag Chemie, Weinheim.

In this context it is preferred that the reduction of the activity of lactate dehydrogenase is achieved by an inactivation of the IdhA-gene (which encodes the lactate dehydrogenase LdhA;

EC 1.1.1.27 or EC 1.1.1.28) and the reduction of the pyruvate formate lyase is achieved by an inactivation of the pfIA-gene (which encodes for an activator of pyruvate formate lyase PfIA; EC 1.97.1.4) or the pfID-gene (which encodes the pyruvate formate lyase PfID; EC 2.3.1.54), wherein the inactivation of these genes (i. e. IdhA, pfIA and pfID) is preferably achieved by a deletion of theses genes or parts thereof, by a deletion of a regulatory element of these genes or at least a part thereof or by an introduction of at least one mutation into these genes, wherein these modifications are preferably performed by means of the “Campbell recombination” as described above.

The IdhA-gene the activity of which is reduced in the modified microorganism according to the present invention preferably comprises a nucleic acid selected from the group consisting of:

Preferred organic compounds that can be produced by the process according to the present invention comprise carboxylic acids such as formic acid, lactic acid, propionic acid, 2-hydroxypropionic acid, 3-hydroxypropionic acid, 3-hydroxybutyric acid, acrylic acid, pyruvic acid or salts of these carboxylic acids, dicarboxylic acids such as malonic acid, succinic acid, malic acid, tartaric acid, glutaric acid, itaconic acid, adipic acid or salts thereof, tricarboxylic acids such as citric acid or salts thereof, alcohols such as methanol or ethanol, amino acids such as L-asparagine, L-aspartic acid, L-arginine, L-isoleucine, L-glycine, Lglutamine, L-glutamic acid, L-cysteine, L-serine, L-tyrosine, L-tryptophan, L-threonine, L-valine, L-histidine, L-proline, L-methionine, L-lysine, L-leucine, etc.

According to a preferred embodiment of the process according to the present invention the organic compound is succinic acid. The term “succinic acid”, as used in the context of the present invention, has to be understood in its broadest sense and also encompasses salts thereof (i. e. succinate), as for example alkali metal salts, like Na + and K + -salts, or earth alkali salts, like Mg 2+ and Ca 2+ -salts, or ammonium salts or anhydrides of succinic acid.

The modified microorganism according to the present invention is preferably incubated in the culture medium at a temperature in the range of about 10 to 60° C. or 20 to 50° C. or 30 to 45° C. at a pH of 5.0 to 9.0 or 5.5 to 8.0 or 6.0 to 7.0.

Preferably, the organic compound, especially succinic acid, is produced under anaerobic conditions. Anaerobic conditions may be established by means of conventional techniques, as for example by degassing the constituents of the reaction medium and maintaining anaerobic conditions by introducing carbon dioxide or nitrogen or mixtures thereof and optionally hydrogen at a flow rate of, for example, 0.1 to 1 or 0.2 to 0.5 vvm. Aerobic conditions may be established by means of conventional techniques, as for example by introducing air or oxygen at a flow rate of, for example, 0.1 to 1 or 0.2 to 0.5 vvm. If appropriate, a slight over pressure of 0.1 to 1.5 bar may be applied in the process.

The assimilable carbon source is preferably selected from the group consisting of sucrose, maltose, maltotriose, maltotetraose, maltopentaose, maltohexaose, maltoheptaose, D-fructose, D-glucose, D-xylose, L-arabinose, D-galactose, D-mannose, glycerol, mixtures thereof and compositions containing at least one of said compounds, or is selected from decomposition products of starch, cellulose, hemicellulose and/or lignocellulose.

The initial concentration of the assimilable carbon source is preferably adjusted to a value in a range of 5 to 100 g/l, preferably 5 to 75 g/l and more preferably 5 to 50 g/l and may be maintained in said range during cultivation. The pH of the reaction medium may be controlled by addition of suitable bases as for example, gaseous ammonia, NH 4 HCO 3 , (NH 4 ) 2 CO 3 , NaOH, Na 2 CO 3 , NaHCO 3 , KOH, K 2 CO 3 , KHCO 3 , Mg(OH) 2 , MgCO 3 , Mg(HCO 3 ) 2 , Ca(OH) 2 , CaCO 3 , Ca(HCO 3 ) 2 , CaO, CH 6 N 2 O 2 , C 2 H 7 N and/or mixtures thereof. These alkaline neutralization agents are especially required if the organic compounds that are formed in the course of the fermentation process are carboxylic acids or dicarboxylic acids. In the case of succinic acid as the organic compound, Mg(OH) 2 and MgCO 3 are particular preferred bases.

The fermentation step I) according to the present invention can, for example, be performed in stirred fermenters, bubble columns and loop reactors. A comprehensive overview of the possible method types including stirrer types and geometric designs can be found in Chmiel: “ Bioprozesstechnik: Einführung in die Bioverfahrenstechnik ”, Volume 1. In the process according to the present invention, typical variants available are the following variants known to those skilled in the art or explained, for example, in Chmiel, Hammes and Bailey: “ Biochemical Engineering ”: such as batch, fed-batch, repeated fed-batch or else continuous fermentation with and without recycling of the biomass. Depending on the production strain, sparging with air, oxygen, carbon dioxide, hydrogen, nitrogen or appropriate gas mixtures may be effected in order to achieve good yield (YP/S).

Particularly preferred conditions for producing the organic compound, especially succinic acid, in process step I) are:

Assimilable carbon source: glycerol, sucrose, D-glucose, maltose, glycerol+D-glucose, glycerol+sucrose, glycerol+maltose, glycerol+D-xylose, D-glucose+fructose Temperature: 30 to 45° C. pH: 5.5 to 7.0 Supplied gas: CO 2

It is furthermore preferred in process step I) that the assimilable carbon source is converted to the organic compound, preferably to succinic acid, with a carbon yield YP/S of at least 0.5 g/g up to about 1.28 g/g; as for example a carbon yield YP/S of at least 0.6 g/g, of at least 0.7 g/g, of at least 0.75 g/g, of at least 0.8 g/g, of at least 0.85 g/g, of at least 0.9 g/g, of at least 0.95 g/g, of at least 1.0 g/g, of at least 1.05 g/g, of at least 1.1 g/g, of at least 1.15 g/g, of at least 1.20 g/g, of at least 1.22 g/g, or of at least 1.24 g/g (organic compound/carbon, preferably succinic acid/carbon).

It is furthermore preferred in process step I) that the assimilable carbon source is converted to the organic compound, preferably to succinic acid, with a specific productivity yield of at least 0.6 g g DCW −1 h −1 organic compound, preferably succinic acid, or of at least of at least 0.65 g g DCW −1 h −1 , of at least 0.7 g g DCW −1 h −1 , of at least 0.75 g g DCW −1 h −1 or of at least 0.77 g g DCW −1 h −1 organic compound, preferably succinic acid.

It is furthermore preferred in process step I) that the assimilable carbon source is converted to the organic compound, preferably to succinic acid, with a space time yield for the organic compound, preferably for succinic acid, of at least 2.2 g/(L×h) or of at least 2.5 g/(L×h), at least 2.75 g/(L×h), at least 3 g/(L×h), at least 3.25 g/(L×h), at least 3.5 g/(L×h), at least 3.7 g/(L×h), at least 4.0 g/(L×h) at least 4.5 g/(L×h) or at least 5.0 g/(L×h) of the organic compound, preferably succinic acid. According to another preferred embodiment of the process according to the present invention in process step I) the modified microorganism is converting at least 20 g/L, more preferably at least 25 g/l and even more preferably at least 30 g/l of the assimilable carbon source to at least 20 g/l, more preferably to at least 25 g/l and even more preferably at least 30 g/l of the organic compound, preferably succinic acid.

The different yield parameters as described herein (“carbon yield” or “YP/S”; “specific productivity yield”; or “space-time-yield (STY)”) are well known in the art and are determined as described for example by Song and Lee, 2006. “Carbon yield” and “YP/S” (each expressed in mass of organic compound produced/mass of assimilable carbon source consumed) are herein used as synonyms. The specific productivity yield describes the amount of a product, like succinic acid, that is produced per h and L fermentation broth per g of dry biomass. The amount of dry cell weight stated as “DCW” describes the quantity of biologically active microorganism in a biochemical reaction. The value is given as g product per g DCW per h (i.e. g g DCW −1 h −1 ). The space-time-yield (STY) is defined as the ratio of the total amount of organic compound formed in the fermentation process to the volume of the culture, regarded over the entire time of cultivation. The space-time yield is also known as the “volumetric productivity”.

In process step II) the organic compound, preferably succinic acid, is recovered from the fermentation broth obtained in process step I).

Usually, the recovery process comprises the step of separating the recombinant microorganisms from the fermentation broth as the so called “biomass”. Processes for removing the biomass are known to those skilled in the art, and comprise filtration, sedimentation, flotation or combinations thereof. Consequently, the biomass can be removed, for example, with centrifuges, separators, decanters, filters or in a flotation apparatus. For maximum recovery of the product of value, washing of the biomass is often advisable, for example in the form of a diafiltration. The selection of the method is dependent upon the biomass content in the fermentation broth and the properties of the biomass, and also the interaction of the biomass with the organic compound (e. the product of value). In one embodiment, the fermentation broth can be sterilized or pasteurized. In a further embodiment, the fermentation broth is concentrated. Depending on the requirement, this concentration can be done batch wise or continuously. The pressure and temperature range should be selected such that firstly no product damage occurs, and secondly minimal use of apparatus and energy is necessary. The skillful selection of pressure and temperature levels for a multistage evaporation in particular enables saving of energy.

The recovery process may further comprise additional purification steps in which the organic compound, preferably succinic acid, is further purified. If, however, the organic compound is converted into a secondary organic product by chemical reactions as described below, a further purification of the organic compound is, depending on the kind of reaction and the reaction conditions, not necessarily required. For the purification of the organic compound obtained in process step II), preferably for the purification of succinic acid, methods known to the person skilled in the art can be used, as for example crystallization, filtration, electrodialysis and chromatography. In the case of succinic acid as the organic compound, for example, succinic acid may be isolated by precipitating it as a calcium succinate product by using calcium hydroxide, -oxide, -carbonate or hydrogen carbonate for neutralization and filtration of the precipitate. The succinic acid is recovered from the precipitated calcium succinate by acidification with sulfuric acid followed by filtration to remove the calcium sulfate (gypsum) which precipitates. The resulting solution may be further purified by means of ion exchange chromatography in order to remove undesired residual ions. Alternatively, if magnesium hydroxide, magnesium carbonate or mixtures thereof have been used to neutralize the fermentation broth, the fermentation broth obtained in process step I) may be acidified to transform the magnesium succinate contained in the medium into the acid form (i. e. succinic acid), which subsequently can be crystallized by cooling down the acidified medium. Examples of further suitable purification processes are disclosed in EP-A1 005 562, WO-A-2008/010373, WO-A-2011/082378, WO-A-2011/043443, WO-A2005/030973, WO-A-2011/123268 and WO-A-2011/064151 and EP-A-2 360 137.

According to a preferred embodiment of the process according to the present invention the process further comprises the process step:

III) conversion of the organic compound contained in the fermentation broth obtained in process step I) or conversion of the recovered organic compound obtained in process step II) into a secondary organic product being different from the organic compound by at least one chemical reaction.

In case of succinic acid as the organic compound preferred secondary organic products are selected from the group consisting of succinic acid esters and polymers thereof, tetrahydrofuran (THF), 1,4-butanediol (BDO), gamma-butyrolactone (GBL) and pyrrolidones.

According to a preferred embodiment for the production of THF, BDO and/or GBL this process comprises:

b1) either the direct catalytic hydrogenation of the succinic acid obtained in process steps I) or II) to THF and/or BDO and/or GBL or b2) the chemical esterification of succinic acid and/or succinic acid salts obtained in process steps I) or II) into its corresponding di-lower alkyl ester and subsequent catalytic hydrogenation of said ester to THF and/or BDO and/or GBL.

According to a preferred embodiment for the production of pyrrolidones this process comprises:

b) the chemical conversion of succinic acid ammonium salts obtained in process steps I) or II) to pyrrolidones in a manner known per se.

For details of preparing these compounds reference is made to US-A-2010/0159543 and WO-A-2010/092155.
