Aspects of the invention relate to engineered organisms for use in the production of molecules for industrial application. As used herein, “engineered organisms” refer to organisms that recombinantly express nucleic acids. In some embodiments, such nucleic acids encode enzymes as discussed herein. Homologs and alleles of genes associated with the invention can be identified by conventional techniques. Also encompassed by the invention are nucleic acids, referred to as “primers” or “primer sets,” that hybridize under stringent conditions to the genes described herein. The term “stringent conditions” as used herein refers to parameters with which the art is familiar. Nucleic acid hybridization parameters may be found in references which compile such methods, e.g. Molecular Cloning: A Laboratory Manual, J. Sambrook, et al., eds., Fourth Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 2012, or Current Protocols in Molecular Biology, F. M. Ausubel, et al., eds., John Wiley & Sons, Inc., New York.
It should be appreciated that the genes associated with invention can be obtained from a variety of sources. It should be further appreciated that any of the nucleic acids and/or polypeptides described herein can be codon-optimized and expressed recombinantly in a codon-optimized form.
As one of ordinary skill in the art would be aware, homologous genes for enzymes described herein could be obtained from other species and could be identified by homology searches, for example through a protein BLAST search, available at the National Center for Biotechnology Information (NCBI) internet site (ncbi.nlm.nih.gov). Genes associated with the invention can be PCR amplified from DNA from any source of DNA which contains the given gene. In some embodiments, genes associated with the invention are synthetic. Any means of obtaining a gene encoding the enzymes associated with the invention are compatible with the instant invention.
In general, homologs and alleles typically will share at least 75% nucleotide identity and/or at least 80% amino acid identity to the sequences of nucleic acids and polypeptides, respectively, in some instances will share at least 90% nucleotide identity and/or at least 90% amino acid identity and in still other instances will share at least 95% nucleotide identity and/or at least 95% or 99% amino acid identity. The homology can be calculated using various, publicly available software tools developed by NCBI (Bethesda, Md.) that can be obtained through the NCBI internet site. Exemplary tools include the BLAST software, also available at the NCBI internet site (www.ncbi.nlm.nih.gov). Pairwise and ClustalW alignments (BLOSUM30 matrix setting) as well as Kyte-Doolittle hydropathic analysis can be obtained using the MacVector sequence analysis software (Oxford Molecular Group). Watson-Crick complements of the foregoing nucleic acids also are embraced by the invention.
The invention also includes degenerate nucleic acids which include alternative codons to those present in the native materials. For example, serine residues are encoded by the codons TCA, AGT, TCC, TCG, TCT and AGC. Each of the six codons is equivalent for the purposes of encoding a serine residue. Thus, it will be apparent to one of ordinary skill in the art that any of the serine-encoding nucleotide triplets may be employed to direct the protein synthesis apparatus, in vitro or in vivo, to incorporate a serine residue into an elongating polypeptide. Similarly, nucleotide sequence triplets which encode other amino acid residues include, but are not limited to: CCA, CCC, CCG and CCT (proline codons); CGA, CGC, CGG, CGT, AGA and AGG (arginine codons); ACA, ACC, ACG and ACT (threonine codons); AAC and AAT (asparagine codons); and ATA, ATC and ATT (isoleucine codons). Other amino acid residues may be encoded similarly by multiple nucleotide sequences. Thus, the invention embraces degenerate nucleic acids that differ from the biologically isolated nucleic acids in codon sequence due to the degeneracy of the genetic code. The invention also embraces codon optimization to suit optimal codon usage of a host cell.
The invention also provides modified nucleic acid molecules which include additions, substitutions and deletions of one or more nucleotides. In preferred embodiments, these modified nucleic acid molecules and/or the polypeptides they encode retain at least one activity or function of the unmodified nucleic acid molecule and/or the polypeptides, such as enzymatic activity. In certain embodiments, the modified nucleic acid molecules encode modified polypeptides, preferably polypeptides having conservative amino acid substitutions as are described elsewhere herein. The modified nucleic acid molecules are structurally related to the unmodified nucleic acid molecules and in preferred embodiments are sufficiently structurally related to the unmodified nucleic acid molecules so that the modified and unmodified nucleic acid molecules hybridize under stringent conditions known to one of skill in the art.
For example, modified nucleic acid molecules which encode polypeptides having single amino acid changes can be prepared. Each of these nucleic acid molecules can have one, two or three nucleotide substitutions exclusive of nucleotide changes corresponding to the degeneracy of the genetic code as described herein. Likewise, modified nucleic acid molecules which encode polypeptides having two amino acid changes can be prepared which have, e.g., 2-6 nucleotide changes. Numerous modified nucleic acid molecules like these will be readily envisioned by one of skill in the art, including for example, substitutions of nucleotides in codons encoding amino acids 2 and 3, 2 and 4, 2 and 5, 2 and 6, and so on. In the foregoing example, each combination of two amino acids is included in the set of modified nucleic acid molecules, as well as all nucleotide substitutions which code for the amino acid substitutions. Additional nucleic acid molecules that encode polypeptides having additional substitutions (i.e., 3 or more), additions or deletions (e.g., by introduction of a stop codon or a splice site(s)) also can be prepared and are embraced by the invention as readily envisioned by one of ordinary skill in the art. Any of the foregoing nucleic acids or polypeptides can be tested by routine experimentation for retention of structural relation or activity to the nucleic acids and/or polypeptides disclosed herein.
The invention embraces variants of polypeptides. As used herein, a “variant” of a polypeptide is a polypeptide which contains one or more modifications to the primary amino acid sequence of the polypeptide. Modifications which create a variant can be made to a polypeptide, for example to: 1) reduce or eliminate an activity of a polypeptide; 2) enhance a property of a polypeptide; 3) provide a novel activity or property to a polypeptide, such as addition of an antigenic epitope or addition of a detectable moiety; or 4) provide equivalent or better binding between molecules (e.g., an enzymatic substrate). Modifications to a polypeptide are typically made to the nucleic acid which encodes the polypeptide, and can include deletions, point mutations, truncations, amino acid substitutions and additions of amino acids or non-amino acid moieties. Alternatively, modifications can be made directly to the polypeptide, such as by cleavage, addition of a linker molecule, addition of a detectable moiety, such as biotin, addition of a fatty acid, and the like. Modifications also embrace fusion proteins comprising all or part of the amino acid sequence. One of skill in the art will be familiar with methods for predicting the effect on protein conformation of a change in protein sequence, and can thus “design” a variant of a polypeptide according to known methods. One example of such a method is described by Dahiyat and Mayo in Science 278:82 87, 1997, whereby proteins can be designed de novo. The method can be applied to a known protein to vary only a portion of the polypeptide sequence. By applying the computational methods of Dahiyat and Mayo, specific variants of a polypeptide can be proposed and tested to determine whether the variant retains a desired conformation.
In general, variants include polypeptides which are modified specifically to alter a feature of the polypeptide unrelated to its desired physiological activity. For example, cysteine residues can be substituted or deleted to prevent unwanted disulfide linkages. Similarly, certain amino acids can be changed to enhance expression of a polypeptide by eliminating proteolysis by proteases in an expression system (e.g., dibasic amino acid residues in yeast expression systems in which KEX2 protease activity is present).
Mutations of a nucleic acid which encode a polypeptide preferably preserve the amino acid reading frame of the coding sequence, and preferably do not create regions in the nucleic acid which are likely to hybridize to form secondary structures, such a hairpins or loops, which can be deleterious to expression of the variant polypeptide.
Mutations can be made by selecting an amino acid substitution, or by random mutagenesis of a selected site in a nucleic acid which encodes the polypeptide. Variant polypeptides are then expressed and tested for one or more activities to determine which mutation provides a variant polypeptide with the desired properties. Further mutations can be made to variants (or to non-variant polypeptides) which are silent as to the amino acid sequence of the polypeptide, but which provide preferred codons for translation in a particular host. The preferred codons for translation of a nucleic acid in, e.g., E. coli, are well known to those of ordinary skill in the art. Still other mutations can be made to the noncoding sequences of a gene or cDNA clone to enhance expression of the polypeptide. The activity of variant polypeptides can be tested by cloning the gene encoding the variant polypeptide into a bacterial or mammalian expression vector, introducing the vector into an appropriate host cell, expressing the variant polypeptide, and testing for a functional capability of the polypeptides as disclosed herein.
The skilled artisan will also realize that conservative amino acid substitutions may be made in polypeptides to provide functionally equivalent variants of the foregoing polypeptides, i.e., the variants retain the functional capabilities of the polypeptides. As used herein, a “conservative amino acid substitution” refers to an amino acid substitution which does not alter the relative charge or size characteristics of the protein in which the amino acid substitution is made. Variants can be prepared according to methods for altering polypeptide sequence known to one of ordinary skill in the art such as are found in references which compile such methods, e.g. Molecular Cloning: A Laboratory Manual, J. Sambrook, et al., eds., Fourth Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 2012, or Current Protocols in Molecular Biology, F. M. Ausubel, et al., eds., John Wiley & Sons, Inc., New York. Exemplary functionally equivalent variants of polypeptides include conservative amino acid substitutions in the amino acid sequences of proteins disclosed herein. Conservative substitutions of amino acids include substitutions made amongst amino acids within the following groups: (a) M, I, L, V; (b) F, Y, W; (c) K, R, H; (d) A, G; (e) S, T; (f) Q, N; and (g) E, D.
In general, it is preferred that fewer than all of the amino acids are changed when preparing variant polypeptides. Where particular amino acid residues are known to confer function, such amino acids will in some embodiments not be replaced, or alternatively, will in some embodiments be replaced by conservative amino acid substitutions. In some embodiments, preferably, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 residues can be changed when preparing variant polypeptides. In some embodiments, it is generally preferred that the fewest number of substitutions is made. Thus, one method for generating variant polypeptides is to substitute all other amino acids for a particular single amino acid, then assay activity of the variant, then repeat the process with one or more of the polypeptides having the best activity.
Conservative amino-acid substitutions in the amino acid sequence of a polypeptide to produce functionally equivalent variants of the polypeptide typically are made by alteration of a nucleic acid encoding the polypeptide. Such substitutions can be made by a variety of methods known to one of ordinary skill in the art. For example, amino acid substitutions may be made by PCR-directed mutation, site-directed mutagenesis according to the method of Kunkel (Kunkel, Proc. Nat. Acad. Sci. U.S.A. 82: 488-492, 1985), or by chemical synthesis of a gene encoding a polypeptide.
It should be appreciated that some cells compatible with the invention may express an endogenous copy of one or more of the genes associated with the invention as well as a recombinant copy. In some embodiments if a cell has an endogenous copy of one or more of the genes associated with the invention then the methods will not necessarily require adding a recombinant copy of the gene(s) that are endogenously expressed. In some embodiments the cell may endogenously express one or more enzymes from the pathways described herein.
In some embodiments, one or more of the genes associated with the invention is expressed in a recombinant expression vector. As used herein, a “vector” may be any of a number of nucleic acids into which a desired sequence or sequences may be inserted by restriction and ligation for transport between different genetic environments or for expression in a host cell. Vectors are typically composed of DNA although RNA vectors are also available. Vectors include, but are not limited to: plasmids, fosmids, phagemids, virus genomes and artificial chromosomes.
A cloning vector is one which is able to replicate autonomously or integrated in the genome in a host cell, and which is further characterized by one or more endonuclease restriction sites at which the vector may be cut in a determinable fashion and into which a desired DNA sequence may be ligated such that the new recombinant vector retains its ability to replicate in the host cell. In the case of plasmids, replication of the desired sequence may occur many times as the plasmid increases in copy number within the host cell such as a host bacterium or just a single time per host before the host reproduces by mitosis. In the case of phage, replication may occur actively during a lytic phase or passively during a lysogenic phase.
An expression vector is one into which a desired DNA sequence may be inserted by restriction and ligation such that it is operably joined to regulatory sequences and may be expressed as an RNA transcript. Vectors may further contain one or more marker sequences suitable for use in the identification of cells which have or have not been transformed or transfected with the vector. Markers include, for example, genes encoding proteins which increase or decrease either resistance or sensitivity to antibiotics or other compounds, genes which encode enzymes whose activities are detectable by standard assays known in the art (e.g., β-galactosidase, luciferase or alkaline phosphatase), and genes which visibly affect the phenotype of transformed or transfected cells, hosts, colonies or plaques (e.g., green fluorescent protein). Preferred vectors are those capable of autonomous replication and expression of the structural gene products present in the DNA segments to which they are operably joined.
As used herein, a coding sequence and regulatory sequences are said to be “operably” joined when they are covalently linked in such a way as to place the expression or transcription of the coding sequence under the influence or control of the regulatory sequences. If it is desired that the coding sequences be translated into a functional protein, two DNA sequences are said to be operably joined if induction of a promoter in the 5′ regulatory sequences results in the transcription of the coding sequence and if the nature of the linkage between the two DNA sequences does not (1) result in the introduction of a frame-shift mutation, (2) interfere with the ability of the promoter region to direct the transcription of the coding sequences, or (3) interfere with the ability of the corresponding RNA transcript to be translated into a protein. Thus, a promoter region would be operably joined to a coding sequence if the promoter region were capable of effecting transcription of that DNA sequence such that the resulting transcript can be translated into the desired protein or polypeptide.
When a nucleic acid molecule encoding an enzyme associated with aspects of the invention is expressed in a cell, a variety of transcription control sequences (e.g., promoter/enhancer sequences) can be used to direct its expression. The promoter can be a native promoter, i.e., the promoter of the gene in its endogenous context, which provides normal regulation of expression of the gene. In some embodiments the promoter can be constitutive, i.e., the promoter is unregulated allowing for continual transcription of its associated gene.

EXAMPLES

Example 1: Production of Amino Acids from Feedstock Consisting of a Syngas, or Components Thereof

Cupriavidus necator (also known as Ralstonia eutropha) strains DSM 531 and DSM541 were cultured using a H₂/CO₂/O₂gas mixture and mineral salt fermentation medium. The culture was grown for 96 hrs in 20 ml MSM medium (1 L Medium A: 9 g Na2HPO412H2O, 1.5 g H2PO4, 1.0 g NH4Cl and 0.2 g MgSO47H2O per 1 L; 10 ml Medium B: 50 mg Ferric ammonium citrate and 100 mg CaCl2 per 100 ml; 10 ml Medium C: 5 g NaHCO3 per 100 ml; and 1 ml Trace Mineral Solution: 100 mg ZnSO47H2O, 30 mg MnCl24H2O, 300 mg H3BO3, 200 mg COCl26H2O, 10 mg CuCl22H2O, 20 mg NiCl26H2O and 30 mg Na2MoO42H2O per 1 L) in a serum bottle supplemented with 66.7% H2, 9.5% CO2, 5% 02 and 18.8% N2 at 30° C. and 200 rpm.
For lysine detection in the growth media, 1 ml of the cells (O.D=0.1) were separated by centrifugation (10,000 rpm, 5 min at room temperature) and the supernatant (200 μl) was further filtrated (0.22μ). Samples of the supernatants were collected and analyzed for secretion of amino-containing compounds, such as amino acids including lysine, tyrosine, and phenylalanine, as shown in Table 2. It was observed that C. necator strain DSM541 secreted higher concentrations of lysine, tyrosine, and phenylalanine into the medium compared to C. necator strain DSM531. The analyses were performed on 200 μl of sterile filtered fermentation medium. Compounds were isolated and derivatized using a clean-up and derivatization kit (e.g. EZ-FaaST (Phenomenex) followed by liquid chromatography-mass spectrometry to separate and identify compounds that had been secreted by the bacterial strains into the medium (Table 2). The levels of lysine found in the media from DSM 541 were 125 fold higher than DSM 531. (FIG. 5).

Example 2: Production of Amino Acids from Feedstock Consisting of a Syngas, or Components Thereof, Using an Engineered Microorganism

Bacterial strains can be genetically modified to increase production of amino-containing molecules such as lysine. Ralstonia eutropha N-1 strain DSM 13513 can be engineered to express exogenous genes or up-regulate native genes coding for enzymes involved in lysine biosynthesis such as aspartate kinase (EC 2.7.2.4, see, for example, SEQ ID NO:1) (Kalinowski et al., 1991), dihydrodipicolinate synthase (EC 4.2.1.52, see, for example, SEQ ID NO:2), (Patek et al., 1997) or in lysine secretion such as lysine exporter (Vrljic et al., 1996) (see, for example, SEQ ID NO:3). In some embodiments, increased lysine production is obtained by down-regulation of enzymes in the citric acid cycle, such as succinyl-CoA synthase (EC 6.2.1.4, see, for example, alpha subunit SEQ ID NO:4 and beta subunit SEQ ID NO:5) (Johnson et al., 1998).
Aromatic amino acids are synthesized through the Shikimate pathway. Bacterial strains are engineered to produce increased quantifies of the aromatic amino acids phenylalanine and tyrosine by over-expressing enzymes in this pathway, such as chorismate synthase (EC 4.2.3.5, SEQ ID NO:6).
Rhodococcus opacus PD630 produces a chorismate synthase for the production of aromatic amino acids (Holder et al., 2011). Basic Local Alignment Search Tool (BLAST) of the protein sequence of the chorismate synthase from Rhodococcus opacus PD360 against the NCBI nr database (All non-redundant GenBank CDS translations+PDB+SwissProt+PIR+PRF excluding environmental samples from WGS projects) reveals multiple protein sequences with high homology. As described herein, homologous proteins can be used for practice of the invention.
To generate a bacterial strain that produces increased quantities of amino acids, expression vectors are constructed. The aspartate kinase, dihydrodipicolinate synthase, and chorismate synthase genes from the Ralstonia eutropha are amplified from the R. eutropha genome using the primer pairs provided by SEQ ID NO:11 and 12, 13 and 14, and 19 and 20, respectively. The genes can also be synthesized. The cloned genes are inserted into a pBBR1 MCS-derived broad host-range vector. In some embodiments, all genes are regulated by a single promoter to yield a single, polycistronic mRNA transcript. Gene expression can be modulated by placing the over-expressed genes under control of the heterologous araBAD promoter or the native rbc promoter (RuBisCO carboxylase/oxygenase promoter). Plasmid manipulation is performed in E. coli.
Plasmids prepared as described above are transformed into Ralstonia eutropha using electroporation (11.5 kV/cm, 25 μF, 5 ms). For plasmid containing an inducible promoter, the inducer molecule will be added to the culture at mid-log phase. In embodiments in which the plasmid contains the rbc promoter, the genes are expressed constitutively.
The genetically modified Ralstonia eutropha is grown to high cell density using a gas-based feedstock such as syngas. Bacterial cells and fermentation supernatant are separated by centrifugation at 10,000 rpm for 10 minutes. To lyse the bacterial cells, pellets are washed twice with 10 mM Tris pH 8.0 containing 10 mM EDTA (TE buffer) and resuspended in TE buffer containing 10% SDS followed by tip sonication (3×30 sec, 30% duty cycle, power level 7). Supernatant is filtered through a 0.2 micron filter. The identification and quantity of free amino acids in the cell extract and in the supernatant (secreted) are determined after purification and derivatization using a clean-up and derivatization kit (e.g., EZ-faast kit (Phenomenex, Torrance, Calif.) followed by High Performance Liquid Chromatography coupled to Mass Spectrometry (HPLC-MS).
Total bacterial protein is isolated by salt precipitation using high concentrations of (NH₄)₂SO₄followed by dialysis. The isolated bacterial protein is hydrolyzed by treatment with HO, and the amino acid composition is determined following separation and quantitation by Ion-Exchange Chromatography. Results of these experiments are expected to show production of amino acids from feedstock consisting of a syngas or components thereof using overexpression in a chemoautotrophic production strain that can be grown to high cell density using a gas-based feedstock.

2.1 Enhanced Production of Lysine

Cupriavidus necator wild type (DSM 531) and the mutant strain that does not form poly-β-hydroxy-butyrate (DSM 541), were grown under chemoautotrophic conditions for 96 hrs in 20 ml MSM medium (1 L Medium A: 9 g Na₂HPO₄12H₂O, 1.5 g H₂PO₄, 1.0 g NH₄Cl and 0.2 g MgSO₄7H₂O per 1 L; 10 ml Medium B: 50 mg Ferric ammonium citrate and 100 mg CaCl₂per 100 ml; 10 ml Medium C: 5 g NaHCO₃per 100 ml; and 1 ml Trace Mineral Solution: 100 mg ZnSO₄7H₂O, 30 mg MnCl₂4H₂O, 300 mg H₃BO₃, 200 mg COCl₂6H₂O, 10 mg CuCl₂2H₂O, 20 mg NiCl₂6H₂O and 30 mg Na₂MoO₄2H₂O per 1 L) in a serum bottle supplemented with 66.7% H₂, 9.5% CO₂, 5% O₂and 18.8% N₂at 30° C. and 200 rpm.
For lysine detection in the growth media, 1 ml of the cells (O.D=0.1) were separated by centrifugation (10,000 rpm, 5 min at room temperature) and the supernatant (200μ1) was further filtrated (0.22μ). The compounds were isolated from the supernatant and derivatized using EZ-FaaST and analyzed by LC-MS. The levels of lysine found in the media from DSM 541 were 125 fold higher than DSM 531. (FIG. 5)

Example 3: Production of Putrescine from Feedstock Consisting of a Syngas, or Components Thereof

Cupriavidus Necator (also known as Ralstonia eutropha) strains DSM 531 and DSM541 were grown on an H₂/CO₂/O₂gas mixture and mineral salt fermentation medium (1 L Medium A: 9 g Na2HPO412H2O, 1.5 g H2PO4, 1.0 g NH4Cl and 0.2 g MgSO47H2O per 1 L; 10 ml Medium B: 50 mg Ferric ammonium citrate and 100 mg CaCl2 per 100 ml; 10 ml Medium C: 5 g NaHCO3 per 100 ml; and 1 ml Trace Mineral Solution: 100 mg ZnSO47H2O, 30 mg MnCl24H2O, 300 mg H3BO3, 200 mg COCl26H2O, 10 mg CuCl22H2O, 20 mg NiCl26H2O and 30 mg Na2MoO42H2O per 1 L) for 96 hours in 20 ml medium in a serum bottle supplemented with 66.7% H2, 9.5% CO2, 5% 02 and 18.8% N2 at 30° C. and 200 rpm.
For putresine detection in the growth media, 1 ml of the cells (O.D=0.1) were separated by centrifugation (10,000 rpm, 5 min at room temperature) and the supernatant was further filtrated (0.22μ). Samples of the supernatant were collected and analyzed for secretion of putrescine into the aqueous broth, as shown in Table 2. It was observed that C. necator strain DSM531 secreted higher concentrations of putrescine into the medium compared to C. necator strain DSM541. The analyses were performed on 200 μl of sterile filtered fermentation broth. Compounds were isolated and derivatized using a clean-up and derivatization kit (e.g., EZ-FaaST (Phenomenex) followed by liquid chromatography-mass spectrometry to separate and identify the compounds that had been secreted by the bacterial strains into the medium (Table 2).

Example 4: Production of Putrescine from Feedstock Consisting of a Syngas, or Components Thereof, Using an Engineered Microorganism

Bacterial strains such as Ralstonia eutropha N-1 strain DSM 13513 can be genetically engineered to increase production of putrescine. Biochemical synthesis of putrescine is achieved by enzymatic degradation of arginine by arginase (EC 3.5.3.1, SEQ ID NO:7), followed by enzymatic decarboxylation of ornithine in a reaction catalyzed by ornithine decarboxylase (EC 4.1.1.17, SEQ ID NO:8). Corynebacterium glutamicum produces an exemplary ornithine decarboxylase that can be used for the production of putrescine (Schneider and Wendisch, 2010).
To generate a bacterial strain that produces increased quantities of putrescine, expression vectors are constructed. The arginase and ornithine decarboxylase genes from Ralstonia eutropha are amplified from the R. eutropha genome using the cloning primer pairs provided by SEQ ID NO 17 and 18, and 21 and 22, respectively. Alternatively, the arginase and ornithine genes can be synthesized. The genes are inserted into a pBBR1 MCS-derived broad host-range vector. In some embodiments, all genes are regulated by a single promoter to yield a single, polycistronic mRNA transcript. Gene expression can be modulated by placing the over-expressed genes under control of the heterologous araBAD promoter or the native rbc promoter (RuBisCO carboxylase/oxygenase promoter). Plasmid manipulation is performed in E. coli.
Plasmids prepared as described above are transformed into Ralstonia eutropha using electroporation (11.5 kV/cm, 25 μF, 5 ms). For plasmids containing an inducible promoter, the inducer molecule is added to the culture at mid-log phase. In embodiments in which the plasmid contains the rbc promoter, the genes are expressed constitutively.
The genetically modified Ralstonia eutropha is grown to high cell densities using a gas-based feedstock such as syngas. Bacterial cells and fermentation supernatant are separated by centrifugation at 10; 000 rpm for 10 minutes. The recovered supernatant is filtered through a 0.2 micron filter. Production and secretion of putrescine are evaluated. The supernatant is also acidified to pH 2 to precipitate soluble proteins; the precipitate is removed by centrifugation.
The pellet of bacterial cells is washed with 0.1 M HCl in 0.25/0.75 water/methanol to recover co-precipitated putrescine hydrochloride. Putrescine purity is assessed by NMR and quantified by pH titration.

Example 5: Production of Caprolactam from Feedstock Consisting of a Syngas, or Components Thereof, Using an Engineered Microorganism

Bacterial strains such as Ralstonia eutropha N-1 strain DSM 13513 can be genetically engineered for the production of caprolactam by expressing genes involved in the biosynthetic pathway. Biochemical synthesis of caprolactam is achieved by enzymatic conversion of lysine through the metabolic pathway: lysine→6-aminohex-2-enoic acid→6-aminocaproic acid→caprolactam. Carbon nitrogen lyase (EC 4.3.1.-) activity converts lysine into 6-aminohex-2-enoic acid (Raemarkers-Franken et al., 2011), which can then be converted into 6-aminocaproic acid using enzymes with α-β-enoate reductase (EC 1.3.1.-) activity, for example enzymes from species such as Acremonium, Clostridium, Moorella and Ochrobactrum (Raemarkers-Franken et al., 2009). An enzyme with amidohydrolase (EC 3.5.2.-) activity (Burgard et al., 2010) catalyzes the conversion of 6-aminocaproic acid to caprolactam.
In some embodiments, an enzyme with tyrosine phenol lyase activity (EC 4.1.99.2, SEQ ID NO:9) can convert tyrosine into phenol, which can then be chemically converted into benzene and caprolactam. Erwinia herbicola produces an exemplary tyrosine phenol lyase that can be used for the production of phenol (Mikami et al., 2000).
Alternatively, phenol can be chemically converted to cyclohexanone which can then be converted to caprolactam.
As an additional alternative, purified lysine can be used for the chemical synthesis of caprolactam (see, for example U.S. Pat. No. 7,399,855 B2 and U.S. Patent Publication US 2010/0145003 A1; Frost 2008; Frost 2010)].
To generate a bacterial strain that produces increased quantities of caprolactam, expression vectors are constructed. Genes for the biosynthesis of caprolactam can be amplified from the genomes of appropriate microorganisms or be synthesized. The genes can be inserted into a pBBR1 MCS-derived broad host-range vector. In some embodiments, all genes are regulated by a single promoter to yield a single, polycistronic mRNA transcript. Gene expression can be modulated by placing the over-expressed genes under control of the heterologous araBAD promoter or the native rbc promoter (RuBisCO carboxylase/oxygenase promoter). Plasmid manipulation is performed in E. coli.
Plasmids prepared as described above can be transformed into Ralstonia eutropha using electroporation (11.5 kV/cm, 25 μF, 5 ms). For plasmids containing an inducible promoter, the inducer molecule can be added to the culture at mid-log phase. In embodiments in which the plasmid contains the rbc promoter, the genes are expressed constitutively.
The genetically modified Ralstonia eutropha is grown to a high cell density using a gas-based feedstock such as syngas. Bacterial cells and fermentation supernatant are separated by centrifugation at 10; 000 rpm for 10 minutes. The recovered supernatant is filtered through a 0.2 micron filter. Production and secretion of lysine, benzene, and caprolactam are evaluated by high-performance liquid chromatography-mass spectrometry or by gas chromatography coupled to mass spectrometry.
Secreted lysine can be purified by running the supernatant through a commercially available ion-exchange resin (e.g., DOWEX (Dow, Pittsburgh, Calif.)).

Example 6: Production of Styrene from Feedstock Consisting of a Syngas, or Components Thereof, Using an Engineered Microorganism

Bacterial strains such as the Cupriavidus necator strain that produces amino acids described in Example 1 can be genetically engineered for the production of styrene.
Styrene can be produced from the aromatic amino acid phenylalanine through the following metabolic pathway: phenylalanine cinnamic acid styrene. Phenylalanine ammonium lyase (EC 4.3.1.24) activity catalyzes the conversion of phenylalanine into cinnamic acid, which can be further converted into styrene through a decarboxylation step. Streptomyces maritimus produces an exemplary phenylalanine ammonium lyase that can be used for the production of cinnamic acid (Piel et al., 2000). Exemplary enzymes that are compatible with the decarboxylation step include those belonging to a family of oxalate decarboxylases (EC 4.1.1.2), for example an oxalate decarboxylase from Rhodococcus jostii RHA1 that can produce styrene ([McLeod et al., 2006)S. In some embodiments, in order to further increase production of styrene, the endogenous styrene degradation pathway can be minimized by down-regulation of the styrene monooxygenase complex (Mooney et al., 2006).
To generate a bacterial strain that produces increased quantities of styrene, expression vectors are constructed. Genes for the biosynthesis of styrene can be amplified from the genomes of appropriate microorganisms or be synthesized. The genes can be inserted into a pBBR1 MCS-derived broad host-range vector. In some embodiments, all genes can be regulated by a single promoter to yield a single, polycistronic mRNA transcript. Gene expression can in some embodiments be modulated by placing the over-expressed genes under control of the heterologous araBAD promoter or the native rbc promoter (RuBisCO carboxylase/oxygenase promoter). Plasmid manipulation is performed in E. coli.
Plasmids prepared as described above can be transformed into Ralstonia eutropha using electroporation (11.5 kV/cm, 25 μF, 5 ms). For plasmids containing an inducible promoter, the inducer molecule can be added to the culture at mid-log phase. In embodiments in which the plasmid contains the rbc promoter, the genes are expressed constitutively.
The genetically modified Ralstonia eutropha is grown to a high cell density using a gas-based feedstock such as syngas. Bacterial cells and fermentation supernatant are separated by centrifugation at 10,000 rpm for 10 minutes. The recovered supernatant is filtered through a 0.2 micron filter. Production and secretion of styrene are evaluated.

Example 7: Production of 1,3-Butanediol from Feedstock Consisting of a Syngas, or Components Thereof

Cupriavidus necator (also known as Ralstonia eutropha) strain DSM541 was cultured using a H₂/CO₂/O₂gas mixture and mineral salt fermentation medium (1 L Medium A: 9 g Na2HPO412H2O, 1.5 g H2PO4, 1.0 g NH4Cl and 0.2 g MgSO47H2O per 1 L; 10 ml Medium B: 50 mg Ferric ammonium citrate and 100 mg CaCl2 per 100 ml; 10 ml Medium C: 5 g NaHCO3 per 100 ml; and 1 ml Trace Mineral Solution: 100 mg ZnSO47H2O, 30 mg MnCl24H2O, 300 mg H3BO3, 200 mg COCl26H2O, 10 mg CuCl22H2O, 20 mg NiCl26H2O and 30 mg Na2MoO42H2O per 1 L). Samples of the supernatant were collected and analyzed for the secretion of 1,3-butanediol by gas chromatography-mass spectrometry (GC-MS), as shown in FIGS. 1A and 1B.

GC-MS

For butanediol analysis, samples were injected manually using a SPME syringe (SPME fiber assembly Polydimethylsiloxane, Sigma Aldrich). Reactor broth samples were placed in 2 mL GC vials with a septum top. The SPME was injected into the samples for 30 seconds and then placed into the GC injector for 5 seconds. Compounds were detected on an Agilent 6890N GC/MS (Agilent, Santa Clara, Calif.) on a HP1 60 m column×0.25 mm ID. The injector temperature was 250° C. and was run in split mote (8:1) with an initial GC temperature of 60° C., ramp at 5° C./min to a final temp of 100° C. which was held for 5 minutes. Peak ID was accomplished through a NIST08 library search and comparison with 1,4-Butanediol standard material. Butanediol standards were prepared by adding known quantities of standard to fresh media and injecting with the same method as the broth samples.

Example 8: Production of 1,3-Butadiene from Feedstock Consisting of a Syngas, or Components Thereof, Using an Engineered Microorganism

Cupriavidus necator strain DSM541 can grow on a carbon-containing gas such as syngas, producer gas, CO2, carbon monoxide and mixtures of the same containing hydrogen gas, to produce polymers of 3-hydroxybutyrate (poly-3-hydroxybutyrate, P3HB). During fermentative growth, P3HB can be degraded, and 3-hydroxybutyrate and 1,3-butanediol are produced. C. necator strains can be genetically engineered to produce increased quantities of butadiene by introducing an exogenous oleate hydratase enzyme (EC 4.2.1.53, SEQ ID NO:10).
To generate a bacterial strain that produces increased quantities of 1,3-butadiene, expression vectors are constructed. A gene encoding an oleate hydratase can be amplified from the genomes of an appropriate microorganism or be synthesized. The gene can be inserted into a pBBR1 MCS-derived broad host-range vector. Gene expression can in some embodiments be modulated by placing the over-expressed genes under control of the heterologous araBAD promoter or the native rbc promoter (RuBisCO carboxylase/oxygenase promoter). Plasmid manipulation is performed in E. coli.
Plasmids prepared as described above can be transformed into Ralstonia eutropha using electroporation (11.5 kV/cm, 25 μF, 5 ms). For plasmids containing an inducible promoter, the inducer molecule can be added to the culture at mid-log phase. In embodiments in which the plasmid contains the rbc promoter, the genes are expressed constitutively.
The genetically modified Ralstonia eutropha is grown to a high cell density using a gas-based feedstock such as syngas. Bacterial cells and fermentation supernatant are separated by centrifugation at 10; 000 rpm for 10 minutes. The recovered supernatant is filtered through a 0.2 micron filter. Production and secretion of butadiene are evaluated.

Samples were injected using an automatic injector, injector temperature was 250° C. and was run in split mote (8:1) with an initial GC temperature of 40° C., ramp at 4° C./min to a final temp of 100° C., then a ramp of 10° C./min to 225° C., finally a 20° C./min ramp to 312 C. Peak ID was accomplished through a NIST08 library.

Example 9: Production of Omega-7 Fatty Acids from Feedstock Consisting of a Syngas, or Components Thereof

Rhodococcus opacus strain DSM 43205 was cultured using a H₂/CO₂/O₂gas mixture and mineral salt fermentation medium. The cell mass was separated from the supernatant of the culture by centrifugation. The supernatant was discarded and a chloroform/methanol (C/M) extraction was performed on the biomass pellet. Lipids were applied to Silica-60 columns, and different lipid groups were separated and eluted from the column with organic solvents including hexane, chloroform, isopropanol, methanol and acetone. Mild alkaline methylation was performed to methylate non-fatty acid lipids and acid methylation was performed to methylate fatty acids. Fatty acid methyl esters (FAMEs) were analyzed by gas chromatography-mass spectrometry (GC-MS). The GC-MS analysis revealed that Rhodococcus opacus strain DSM 43205 cultured with the gas mixture produced triacylglycerols, which contained high amounts of omega-7 fatty acids, including palmitoleic acid (C16:1, also known as 9-hexadecenoic acid) and vaccenic acid (C18:1, also known as 11-octadecenoic acid) as shown in FIG. 4. Analysis of the biomass showed 40% lipid content; further analysis of the lipid content showed 13% C16:1 omega 7 fatty acid (palmitoleic acid) and 21% C18:1 omega 7 fatty acid (vaccenic acid). Table 1 provides the lipid content and growth conditions for the samples presented in FIG. 4.

GC-MS

For FAME analysis, compounds were detected on an Agilent 6890N GC/MS (Agilent, Santa Clara, Calif.) on a HP1 60 m column×0.25 mm ID. Samples were placed in GC vial inserts with a final volume in hexane of 50 uL. Samples were injected using an automatic injector, the injector temperature was 250° C. and was run in split mote (8:1) with an initial GC temperature of 100° C., ramp at 10° C./min to a final temp of 150° C., then a ramp of 3° C./min to 250° C., finally a 10° C./min ramp to 312° C. which is held for 7 min. Peak ID was accomplished through a NIST08 library and comparison to known standards (Supelco 37 Component FAME Mix). Quantification was accomplished through an external standard added to each sample prior to injection (methyl undecanoate) and extraction efficiency was quantified by an internal standard (1,2-dinonadecanoyl-sn-glycero-3-phosphocholine).

Example 10: Production of Omega-7 Fatty Acids from Feedstock Consisting of a Syngas, or Components Thereof

As demonstrated in Example 9 and FIG. 4, Rhodococcus opacus strain DSM 43205 can grow on a carbon-containing gas such as syngas, producer gas, CO₂, carbon monoxide and mixtures of the same containing hydrogen gas; and/or C1 compounds, to produce and accumulate lipids, including triacylglycerols, which contain high amounts of omega-7 fatty acids, including palmitoleic acid (C16:1) and vaccenic acid (C18:1).
Production of omega-7 fatty acids is further enhanced by culturing Rhodococcus opacus strain DSM 43205 to a high cell density using a gas feedstock, turning off the input of nitrogen nutrient (ammonium) and/or phosphorous nutrient (phosphate) to facilitate the accumulation of lipids including triacylglycerols. The cells are harvested by spinning at 10000 rpm for 10 minutes and the wet mass is applied to a lyophilizer overnight to obtain dry cell material. The lipids are extracted by adding methanol to the dry cell material and incubating at 60° C. for 30 minutes followed by the addition of 2 volumes of chloroform and shaking at 40° C. for 30 minutes. The extract is spun at 1500 rpm for 5 minutes and supernatant containing the lipids is recovered. The lipids are applied to Silica-60 columns and the different lipid groups are separated and eluted from the column with organic solvents including hexane, chloroform, isopropanol, methanol and acetone. The different lipid fractions are analyzed by gas chromatography-mass spectrometry.

Cupriavidus Necator (also known as Ralstonia eutropha) strain DSM531 was cultured using a H2/CO2/O2 gas mixture and mineral salt fermentation medium (1 L Medium A: 9 g Na2HPO412H2O, 1.5 g H2PO4, 1.0 g NH4Cl and 0.2 g MgSO47H2O per 1 L; 10 ml Medium B: 50 mg Ferric ammonium citrate and 100 mg CaCl2 per 100 ml; 10 ml Medium C: 5 g NaHCO3 per 100 ml; and 1 ml Trace Mineral Solution: 100 mg ZnSO47H2O, 30 mg MnCl24H2O, 300 mg H3BO3, 200 mg COCl26H2O, 10 mg CuCl22H2O, 20 mg NiCl26H2O and 30 mg Na2MoO42H2O per 1 L) and found to produce and accumulate biopolymers including PHBs.
Strain DSM531 was grown to high cell density using a gas feedstock (up to optical density between 60 to 130 at 650 nm). Cells were harvested by spinning at 10000 rpm for 10 minutes. Wet mass was applied to a lyophilizer overnight to obtain dry cell material. Biopolymers were extracted by adding chloroform to the dry cell material and incubating at 60 degrees Celsius for 4 hours. Extract was spun at 1500 rpm for 5 minutes and supernatant containing the extracted biopolymers was recovered. Supernatant was concentrated under nitrogen and biopolymers was precipitated and recovered by adding concentrated supernatant to 4 volumes of ice-cold methanol and spinning at 1500 rpm for 5 minutes (FIG. 2). Recovered biopolymers were re-dissolved in chloroform. Monomer production was facilitated by adding methanol and sulfuric acid and incubation at 100 degrees Celsius for 2 hours. Following the addition of water to create a 2-phase extraction system, the monomeric methyl-ester was isolated in the organic phase and analyzed by GC/MS (FIG. 3A-3D).
