Description

[Technical field]

[0001] The present invention relates to a microorganism capable of producing a monoterpenoid and a method for producing a monoterpenoid using the microorganism. [Background technology]

[0002] Monoterpenoids are compounds whose basic structure consists of two isoprene (2-methyl-1,3-butadiene) units. Monoterpenoids include linear (acyclic) and ring-containing (monocyclic, polycyclic) monoterpenoids, and some have various functional groups due to modifications such as oxidation and rearrangement reactions. Monoterpenoids are known to have various physiological activities and functions, such as limonene, perillyl alcohol, perillyl aldehyde, and perillic acid. These have attracted attention as ingredients that exhibit fragrances, food additives, antibacterial, anticancer, and antioxidant effects. In addition, methyl perillate can be derived into cumic acid, terephthalic acid, and other compounds through chemical synthesis reactions under mild conditions, and is attracting attention as an aromatic compound derivative. On the other hand, a method for producing perillyl alcohol from glucose has been reported (Non-Patent Document 1: Jorge Alonso-Gutierrez et al., Metabolic Engineering 19 (2013) 33-41).

[Diagram 2] FIG. 2 is a graph showing the results of measuring the amount of methyl perillate produced in the microorganism of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The present invention will be described in detail below. The following embodiments are merely illustrative for explaining the present invention, and are not intended to limit the present invention to these embodiments. The present invention can be embodied in various forms without departing from the gist of the present invention.

[0010] 1. overview Monoterpenoids include limonene, perillyl alcohol, perillyl aldehyde, and perillic acid, which are attracting attention as ingredients that exhibit fragrances, food additives, antibacterial, anticancer, and antioxidant properties, etc. In addition, methyl perillate can be derived into cumic acid, terephthalic acid, etc. through chemical synthesis reactions under mild conditions, and is attracting attention as an aromatic compound derivative. However, aromatic compounds such as cumic acid and terephthalic acid are not easy to chemically synthesize due to their complex structures, and extracting these compounds from natural resources has been inefficient because the compounds are only present in trace amounts in plants, etc. Therefore, there is a need to establish technology that enables the efficient production of various isoprenoids or monoterpenoids that can be derived from these aromatic compounds. A method for producing perillyl alcohol from glucose has been reported (Jorge Alonso-Gutierrez et al., Metabolic Engineering 19 (2013) 33-41), but this report makes no mention of the production of perillyl aldehyde, perillic acid, or methyl perillate. In light of these circumstances, the present inventors have succeeded in efficiently producing monoterpenoids from organic raw materials by using microorganisms that have been modified to enhance the activity or expression of enzymes such as limonene synthase (LS), limonene-7-hydroxylase (L7H), perillyl alcohol dehydrogenase (POHDH), perillyl aldehyde dehydrogenase (PAldDH), and perillic acid-O-methyltransferase (PAOMT), thereby completing the present invention. The present invention makes it possible to provide a microorganism having a seamless production pathway from glucose to methyl perillate, and by enhancing the activity or expression of each enzyme involved in this pathway, it becomes possible to efficiently produce monoterpenoids such as methyl perillate from organic raw materials. The microorganism of the present invention and the method for producing a monoterpenoid using said microorganism are extremely useful in that they enable efficient production of a monoterpenoid from an organic raw material in a single system.

[0011] 2. Microorganisms capable of producing monoterpenoids (1) Monoterpenoids Monoterpenoids are compounds whose basic structure consists of two isoprene (2-methyl-1,3-butadiene) units. Monoterpenoids are either linear (acyclic) or contain rings (monocyclic, polycyclic), and some have various functional groups due to modifications such as oxidation and rearrangement reactions. In the present invention, examples of monoterpenoids include monoterpenoids having a limonene skeleton, and examples of monoterpenoids having a limonene skeleton include, but are not limited to, limonene, perillyl alcohol, perillyl aldehyde, perillic acid, methyl perillate, and γ-terpinene.

[0012] (2) Monoterpenoid production In the present invention, "production" of a monoterpenoid means that an organism (e.g., a microorganism) produces a monoterpenoid, and in this specification, "production" can be used interchangeably with "production" or "generation." Those skilled in the art can evaluate whether or not a monoterpenoid has been produced by known methods, for example, by separating an organic layer from a test sample (e.g., a culture solution of a microorganism) by liquid-liquid extraction and analyzing the organic layer using a gas chromatography mass spectrometer or the like. For example, if the gas chromatography analysis shows that a peak of the target monoterpenoid contained in the test sample appears at the same position as the peak of the target monoterpenoid (e.g., methyl perillate) contained in the preparation, it can be seen that the target monoterpenoid has been produced in the test sample. However, in the present invention, the method of measuring the amount of production or detecting the production of a monoterpenoid can be appropriately adopted by those skilled in the art and is not limited to the above-mentioned method.

[0013] (3) microorganisms In the present invention, a microorganism capable of producing a monoterpenoid means a microorganism that has been modified so as to efficiently produce a monoterpenoid. In the present invention, such microorganisms include, but are not limited to, the following microorganisms: (a) limonene synthase (LS), (b) limonene-7-hydroxylase (L7H), and (c) at least one enzyme selected from the group consisting of perillyl alcohol dehydrogenase (POHDH), perillyl aldehyde dehydrogenase (PAldDH), and perillic acid-O-methyltransferase (PAOMT); A microorganism modified to enhance the activity or expression of.

[0014] In the present invention, limonene synthase (LS) is an enzyme that catalyzes a reaction in which geranyl pyrophosphate (GPP) is cyclized to synthesize limonene. In the present invention, limonene-7-hydroxylase (L7H) is an enzyme that catalyzes the reaction of hydroxylating the carbon atom at position 7 of limonene to produce perillyl alcohol. As the limonene-7-hydroxylase (L7H), any enzyme that catalyzes the reaction of hydroxylating the carbon atom at position 7 of limonene to produce perillyl alcohol can be used without any particular limitation, and p-cymene monooxygenase (CymAab) can also be used. CymAab is an enzyme that catalyzes the reaction of hydroxylating the carbon atom at position 7 of p-cymene to produce 4-isopropylbenzyl alcohol, but it may also recognize limonene as a substrate and have L7H activity. Therefore, CymAab can also be used in the reaction of producing perillyl alcohol from limonene. This enzyme is composed of a hydroxylase subunit (CymAa) and a reductase subunit (CymAb). Therefore, in this specification, L7H may be referred to as "CymAab", and the subunits may be referred to as "CymAa" and "CymAb", respectively. In the present invention, perillyl alcohol dehydrogenase (POHDH) is an enzyme that catalyzes the reaction of oxidizing (dehydrogenating) perillyl alcohol to produce perillyl aldehyde. As perillyl alcohol dehydrogenase (POHDH), any enzyme that catalyzes the reaction of oxidizing (dehydrogenating) perillyl alcohol to produce perillyl aldehyde can be used without any particular limitation, and 4-isopropylbenzyl alcohol dehydrogenase (CymB) can also be used. CymB catalyzes the reaction of oxidizing (dehydrogenating) 4-isopropylbenzyl alcohol to produce 4-isopropylbenzaldehyde, while also recognizing perillyl alcohol as a substrate and may have POHDH activity. Therefore, CymB can also be used in the reaction of producing perillyl aldehyde from perillyl alcohol. In this way, CymB can have POHDH activity, and therefore POHDH may be referred to as "CymB" in this specification. In the present invention, perillyl aldehyde dehydrogenase (PAldDH) is an enzyme that catalyzes the reaction of oxidizing perillyl aldehyde to produce perillic acid. As perillyl aldehyde dehydrogenase (PAldDH), any enzyme that catalyzes the reaction of oxidizing perillyl aldehyde to produce perillic acid can be used without particular limitation, and 4-isopropylbenzaldehyde dehydrogenase (CymC) can also be used. CymC catalyzes the reaction of oxidizing 4-isopropylbenzaldehyde to produce cumic acid, while also recognizing perillyl aldehyde as a substrate and may have PAldDH activity. Therefore, CymC can also be used in the reaction of producing perillic acid from perillyl aldehyde. In this way, CymC can have PAldDH activity, and therefore, in this specification, PAldDH may be referred to as "CymC". In the present invention, perillic acid-O-methyltransferase (PAOMT) is an enzyme that catalyzes a reaction in which a methyl group is transferred (methylated) to the hydroxyl group (-OH) of perillic acid to produce methyl perillate.

[0015] In the present invention, a microorganism that has been modified to enhance the activity or expression of geranyl pyrophosphate synthase (GPPS) and / or neryl pyrophosphate synthase (NPPS) in addition to the above enzymes (a) to (c) can be used.

[0016] Furthermore, in the present invention, in addition to the enzymes (a) to (c) above, (i) GPPS and / or NPPS, and / or (ii) at least one enzyme selected from the group consisting of acetyl-CoA acetyltransferase (AtoB), 3-hydroxy-3-methylglutaryl-CoA synthase (HMGS), 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR), mevalonate kinase (MVK), phosphomevalonate kinase (PMK), diphosphomevalonate decarboxylase (MVD), and isopentyl diphosphate isomerase (IDI). Microorganisms that have been modified to enhance the activity or expression of can be used.

[0017] Furthermore, in the present invention, in addition to the above enzymes (a) to (c), the following enzymes (i) to (iii): (i) GPPS and / or NPPS; (ii) at least one enzyme selected from the group consisting of AtoB, HMGS, HMGR, MVK, PMK, MVD, and IDI; and (iii) at least one enzyme selected from the group consisting of 1-deoxy-D-xylulose 5-phosphate synthase (Dxs), 1-deoxy-D-xylulose 5-phosphate reductoisomerase (Dxr), 2-C-methyl-D-erythritol 4-phosphate cytidyltransferase (IspD), 4-diphosphocytidyl-2-C-methyl-D-erythritol kinase (IspE), 2-C-methyl-D-erythritol 2,4-cyclodiphosphate synthase (IspF), 1-hydroxy-2-methyl-2-butenyl 4-diphosphate synthase (IspG), and 1-hydroxy-2-methyl-2-butenyl 4-diphosphate reductase (IspH). A microorganism that has been modified so as to enhance the activity or expression of at least one enzyme selected from the group consisting of:

[0018] Furthermore, in the present invention, in addition to the above enzymes (a) to (c), the following enzymes (i) to (iii): (i) GPPS and / or NPPS; (ii) at least one enzyme selected from the group consisting of AtoB, HMGS, HMGR, MVK, PMK, MVD, and IDI; and (iii) at least one enzyme selected from the group consisting of Dxs, Dxr, IspD, IspE, IspF, IspG and IspH and / or (iv) Microorganisms can be used that have been modified to reduce the activity or expression of phosphoglucose isomerase (Pgi) and / or citrate synthase (GltA).

[0019] Furthermore, in the present invention, a microorganism modified to enhance the activity or expression of an enzyme (MvaE) having both AtoB and HMGR activities, instead of enhancing the activity or expression of AtoB and HMGR as described in (ii) above, can also be used. 3-Hydroxy-3-methylglutaryl-CoA synthase derived from a microorganism having MvaE is sometimes called MvaS, and HMGS is sometimes referred to as "MvaS" in this specification.

[0020] As used herein, "modified to enhance activity or expression" of an enzyme means that the activity or expression of the enzyme is enhanced by, for example, 5% or more, 10% or more, 15% or more, 20% or more, 25% or more, 30% or more, 35% or more, 40% or more, 45% or more, 50% or more, 55% or more, 60% or more, 65% or more, 70% or more, 75% or more, 80% or more, 85% or more, 90% or more, 95% or more, or 100% or more, compared to the activity or expression of the enzyme in a non-modified cell (a cell that has not been modified). Whether the activity or expression of the enzyme is enhanced can be evaluated by measuring the expression level of the enzyme in a modified cell and examining whether the expression level is increased compared to that in a non-modified cell.

[0021] As used herein, "modified to reduce activity or expression" of an enzyme means that the activity or expression of the enzyme has been modified to be reduced, for example, by 5% or more, 10% or more, 15% or more, 20% or more, 25% or more, 30% or more, 35% or more, 40% or more, 45% or more, 50% or more, 55% or more, 60% or more, 65% or more, 70% or more, 75% or more, 80% or more, 85% or more, 90% or more, 95% or more, 99% or more, or 100% compared to the activity or expression of the enzyme in a non-modified cell (a cell that has not been modified) ("100% reduction" can also be rephrased as "eliminated"). Whether the activity or expression of the enzyme is reduced can be assessed by measuring the expression level of the enzyme in the modified cells and determining whether the expression level is reduced or the expression of the enzyme is eliminated compared to unmodified cells. Furthermore, a cell in which the gene for a certain enzyme has been disrupted can be evaluated as a cell that has been "modified so that the activity or expression" of that enzyme is reduced (eliminated).

[0022] Examples of microorganisms modified to enhance the activity or expression of the above enzymes (a) to (c) include: (a) DNA encoding limonene synthase (LS) (b) DNA encoding limonene-7-hydroxylase (L7H), and (c) DNA encoding at least one enzyme selected from the group consisting of perillyl alcohol dehydrogenase (POHDH), perillyl aldehyde dehydrogenase (PAldDH), and perillic acid-O-methyltransferase (PAOMT). Microorganisms including

[0023] Examples of microorganisms that have been modified to enhance the activity or expression of GPPS, NPPS, AtoB, HMGS, HMGR, MVK, PMK, MVD, IDI, Dxs, Dxr, IspD, IspE, IspF, IspG, and IspH include microorganisms containing DNA encoding each of GPPS, NPPS, AtoB, HMGS, HMGR, MVK, PMK, MVD, IDI, Dxs, Dxr, IspD, IspE, IspF, IspG, and IspH. Examples of microorganisms that have been modified to reduce the activity or expression of Pgi and / or GltA include microorganisms that have been modified by a method of destroying the nucleic acids that encode these enzymes on the chromosome of the microorganism, a method of replacing the promoters of the nucleic acids that encode these enzymes with weaker promoters, a method of modifying expression regulatory sequences such as the promoters and ribosome binding sequences (SD sequences) of the nucleic acids that encode these enzymes so as to reduce the expression levels, a method of suppressing translation by expressing antisense RNA to inhibit ribosome binding to target mRNA, a method of suppressing transcription by CRISPR interference, and a method of reducing the activity per enzyme molecule by introducing mutations into the nucleic acids (DNA, RNA, etc.) that encode these enzymes. In the present invention, a "modified microorganism" and a microorganism containing DNA encoding each enzyme can also be referred to as a "transformant."

[0024] The DNAs encoding LS, L7H (CymAab), POHDH (CymB), PAldDH (CymC), PAOMT, GPPS, NPPS, AtoB, HMGS, HMGR, MVK, PMK, MVD, IDI, Dxs, Dxr, IspD, IspE, IspF, IspG, and IspH can be prepared by obtaining information on their nucleotide sequences from a known database, such as NCBI (https: / / www.ncbi.nlm.nih.gov / nucleotide / ), and using known genetic engineering techniques. In addition, if a known construct (e.g., pJBEI6409) containing a portion of the above DNA is already available, such a construct can also be used.

However, the base sequences of the DNAs encoding the above-mentioned enzymes and the amino acid sequences of the above-mentioned enzymes in the present invention are not limited to these. As described above, a person skilled in the art can appropriately optimize (such as codon optimization) a desired base sequence based on the information of these base sequences or amino acid sequences.

[0025] In the present invention, a vector containing the DNA encoding each enzyme can be used to genetically introduce the DNA into a microorganism. Examples of such vectors include a plasmid vector and a virus vector. Those skilled in the art can appropriately select the type of vector depending on the type and purpose of the host microorganism. The vector of the present invention can contain, in addition to the DNA encoding the above enzymes, cis elements such as a promoter and an enhancer, a splicing signal, a polyA addition signal, a ribosome binding sequence (SD sequence), a selection marker gene, a reporter gene, and the like, and these can also be modified. The vector of the present invention is not limited as long as it can express the enzyme used in the present invention in a host microorganism, and for example, a vector capable of expressing two or more enzyme genes can be used. In the case of a plasmid vector, such a vector includes, but is not limited to, the pBBRA-1.1e vector, the pUCSp-2 vector, and the pUCAp-2 vector.

[0026] In the present invention, a vector can contain DNA encoding one or more enzymes. For example, one vector can contain, but is not limited to, DNA encoding CymAab (CymAa and CymAb), DNA encoding CymB and CymC, DNA encoding CymAab (CymAa and CymAb), DNA encoding AtoB, HMGS and HMGR, DNA encoding MVK, PMK, MVD and IDI, DNA encoding GPPS and LS, DNA encoding AtoB, HMGS, HMGR, MVK, PMK, MVD, IDI, GPPS and LS, etc.

[0027] In the present invention, for example, by introducing a DNA encoding LS into a microorganism, the activity or expression of LS in the microorganism can be enhanced. This can improve the production of limonene from an organic raw material such as glucose. Furthermore, by introducing a DNA encoding GPPS in addition to LS into a microorganism, the activity or expression of GPPS in the microorganism can be enhanced, and this can further improve the production of limonene from an organic raw material such as glucose. Specifically, in a microorganism, for example, acetyl CoA is supplied from glucose, and isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) are produced from the supplied acetyl CoA via the methylerythritol phosphate pathway (2-C-methyl-D-erythritol 4-phosphate pathway: MEP pathway) and / or the mevalonate pathway (MVA pathway). Geranyl diphosphate (GPP) is produced from the produced IPP and DMAPP by the action of GPPS, and limonene is produced from GPP by the action of LS. That is, in the present invention, in a microorganism containing DNA encoding LS or DNA encoding LS and GPPS, it is possible to improve the production of limonene from an organic raw material such as glucose. Note that in the present invention, enhancement of the activity or expression of GPPS is selective and not essential.

[0028] Furthermore, in the present invention, by introducing a DNA encoding L7H(CymAab) into a microorganism, the activity or expression of L7H(CymAab) in the microorganism can be enhanced, thereby improving the production of perillyl alcohol from limonene. That is, in the present invention, the production of perillyl alcohol from limonene can be improved in a microorganism containing a DNA encoding L7H(CymAab).

[0029] Furthermore, in the present invention, by introducing a DNA encoding POHDH (CymB) into a microorganism, the activity or expression of POHDH (CymB) in the microorganism can be enhanced, thereby improving the production of perillyl aldehyde from perillyl alcohol. That is, in the present invention, the production of perillyl aldehyde from perillyl alcohol can be improved in a microorganism containing a DNA encoding POHDH (CymB).

[0030] Furthermore, in the present invention, by introducing DNA encoding PAldDH (CymC) into a microorganism, the activity or expression of PAldDH (CymC) in the microorganism can be enhanced, thereby improving the production of perillic acid from perillic aldehyde. That is, in the present invention, the production of perillic acid from perillic aldehyde can be improved in a microorganism containing DNA encoding PAldDH (CymC).

[0031] Furthermore, in the present invention, by introducing a DNA encoding PAOMT into a microorganism, the activity or expression of PAOMT in the microorganism can be enhanced, thereby improving the production of methyl perillate from perillic acid. That is, in the present invention, the production of methyl perillate from perillic acid can be improved in a microorganism containing a DNA encoding PAOMT.

[0032] The DNA encoding LS, the DNA encoding L7H (CymAab), the DNA encoding POHDH (CymB), the DNA encoding PAldDH (CymC), and the DNA encoding PAOMT can be combined and introduced into one type of microorganism. This allows for improved production of methyl perillate from organic raw materials such as glucose in a single system. In other words, the present invention allows for the introduction of a seamless production pathway from glucose to methyl perillate into a microorganism, and by enhancing the activity or expression of each enzyme involved in this pathway, it becomes possible to efficiently produce monoterpenoids such as methyl perillate from organic raw materials.

[0033] Thus, in the present invention, for example, by introducing DNA encoding each of the above enzymes into a microorganism, a microorganism modified to enhance the activity or expression of the enzyme can be produced. Methods for introducing DNA into a microorganism are known, and a person skilled in the art can use known gene introduction methods depending on the type of microorganism and DNA. Examples of such methods include a method of introducing a nucleic acid encoding an enzyme into a vector and transforming a microorganism with the vector system, a method of introducing an expression cassette containing a nucleic acid encoding an enzyme into the chromosome of a microorganism, a method of replacing a promoter of a nucleic acid encoding an enzyme with a stronger promoter, a method of modifying an expression regulatory sequence such as a promoter or a ribosome binding sequence (SD sequence) of a nucleic acid encoding an enzyme so as to increase the expression level, and a method of increasing the activity per molecule of an enzyme by introducing a mutation into a nucleic acid encoding an enzyme. In the present invention, a microorganism modified to reduce the activity or expression of Pgi and / or GltA can be prepared using known techniques. Examples of such techniques include a technique for destroying the nucleic acid encoding these enzymes on the chromosome of a microorganism, a technique for replacing the promoter of the nucleic acid encoding these enzymes with a weaker promoter, a technique for modifying the expression regulatory sequence such as the promoter or ribosome binding sequence (SD sequence) of the nucleic acid encoding these enzymes so as to reduce the expression level, a technique for suppressing translation by expressing antisense RNA to inhibit ribosome binding to target mRNA, a technique for suppressing transcription by CRISPR interference, and a technique for reducing the activity per enzyme molecule by introducing a mutation into the nucleic acid (DNA, RNA, etc.) encoding these enzymes.

[0034] In the present invention, a tag can be fused to an enzyme protein. That is, in the present invention, a DNA encoding a fusion protein of a tag and an enzyme can be used. Examples of tags that can be used in the present invention include, but are not limited to, tags that promote solubilization to improve the soluble expression of an enzyme, and tags for purification (e.g., His tags). Examples of tags that promote solubilization of an enzyme include, but are not limited to, Sumo, Fh8, GST, and the like. By fusing a tag that promotes solubilization of an enzyme to an enzyme (e.g., PAOMT), the soluble expression of the enzyme is promoted, and as a result, the production amount of monoterpenoids such as methyl perillate can be improved.

[0035] The microorganisms used in the present invention are not limited as long as they can express the enzymes used in the present invention, and examples thereof include Escherichia coli, coryneform bacteria, Bacillus bacteria, Pantoea bacteria, Enterobacter bacteria, Pseudomonas bacteria, Streptomyces bacteria, Actinomyces bacteria, filamentous fungi, yeast, etc. Those skilled in the art can appropriately select expression vectors so that the enzymes of the present invention can be expressed in these microorganisms, and can also optimize the codons of DNA encoding the enzymes according to the types of these microorganisms.

[0036] Furthermore, those skilled in the art can appropriately set the culture conditions (temperature, time, medium composition, etc.) of the microorganisms used in the present invention and the reaction conditions (temperature, reaction time, pH, etc.) of the enzymes used in the present invention depending on the type of microorganism.

[0037] 3. Method for producing monoterpenoids (1) Monoterpenoids As stated in “2(1)” above. (2) Method for producing monoterpenoids In the present invention, the method for producing monoterpenoids includes a step of reacting an organic raw material with the microorganism described above in "2.(3) Microorganisms." In the present invention, "acting an organic raw material with a microorganism" means culturing the microorganism in the presence of the organic raw material. In the present invention, the term "organic raw material" refers to a carbon source or nitrogen source that can be assimilated and grown by microorganisms. Examples of carbon sources include, but are not limited to, sugars, alcohols, and organic acids, and examples of nitrogen sources include, but are not limited to, organic nitrogen compounds.

[0038] Furthermore, the method for producing a monoterpenoid of the present invention may include, for example, the following steps. (a) preparing and culturing a microorganism comprising at least one DNA selected from (i) a DNA encoding LS, (ii) a DNA encoding L7H, and (iii) a DNA encoding at least one enzyme selected from the group consisting of POHDH, PAldDH, and PAOMT; (b) adding an organic raw material to the culture solution of the microorganism obtained in the step (a) and further culturing the mixture;

[0039] The microorganism in the above step (a) may further contain DNA encoding GPPS and / or NPPS. The microorganism in the above step (a) may further contain DNA encoding at least one enzyme selected from the group consisting of AtoB, HMGS, HMGR, MVK, PMK, MVD and IDI. The microorganism in step (a) may further contain DNA encoding at least one enzyme selected from the group consisting of Dxs, Dxr, IspD, IspE, IspF, IspG and IspH. The microorganism in step (a) may further include a sequence modification on the chromosome that reduces the activity or expression of Pgi and / or GltA, for example, a deletion or mutation in the Pgi and / or GltA gene or its promoter sequence on the chromosome. The microorganism in step (a) may further include an RNA or protein that suppresses the expression of Pgi and / or GltA, for example, an antisense RNA complementary to a ribosome binding sequence, Cas9 (dCas9) lacking nuclease activity, a guide RNA targeting the Pgi and / or GltA gene, etc.

[0040] Furthermore, the production method of the present invention may further include a step of recovering the produced monoterpenoid. Furthermore, the production method of the present invention may further include a step of purifying the produced monoterpenoid. Those skilled in the art can recover and purify the produced monoterpenoid by known methods suited to the physical properties of the monoterpenoid, such as distillation, membrane dehydration, desalting using ion exchange resins, crystallization, column chromatography, and the like.

[0041] In the present invention, when Escherichia coli is used as the microorganism, the method for producing monoterpenoids can be carried out, for example, as follows, but is not limited thereto. First, a transformant is prepared by introducing DNA encoding each enzyme into the host Escherichia coli, and the transformant is cultured overnight at about 37° C. in a known culture medium (e.g., LB medium). Next, when the monoterpenoid to be produced is perillic acid, the grown transformant is suspended in a minimal medium (e.g., M9 medium) containing an organic source (e.g., glucose) and incubated at about 37°C until an appropriate OD 600The transformants are cultured until the enzyme activity or expression reaches a certain value, and then expression of the enzyme genes is induced using IPTG or the like. The transformants in which the activity or expression of each enzyme has been enhanced are contacted with the organic raw material, and then cultured at about 37° C. for an appropriate period of time (e.g., 24 hours). The minimal medium may contain known antibiotics. On the other hand, when the monoterpenoid to be produced is methyl perillate, the grown transformant is suspended in Terrific Broth (TB medium) containing an organic source (e.g., glucose) and incubated at about 37°C until an appropriate OD 600 The transformants are cultured until the enzyme activity or expression reaches a certain value, and then expression of the enzyme genes is induced using IPTG or the like. The transformants in which the activity or expression of each enzyme has been enhanced are contacted with the organic raw material, and then cultured at about 20° C. for an appropriate period of time (e.g., 48 hours). The TB medium may contain known antibiotics. Next, the obtained culture liquid is mixed with an organic solvent (e.g., ethyl acetate) to perform liquid-liquid extraction, and the organic layer containing the extract is analyzed by a known method, for example, gas chromatography. As a result of the gas chromatography analysis, the presence or absence of a peak exhibited by the target monoterpenoid is confirmed, and if a peak is present, it indicates that the target monoterpenoid has been produced. The production amount of the monoterpenoid can be calculated by creating a calibration curve using a commercially available monoterpenoid.

[0042] 4. Method for producing aromatic compounds In the present invention, aromatic compounds can be produced using monoterpenoids (e.g., methyl perillate) produced by the method for producing monoterpenoids of the present invention. That is, the present invention provides a method for producing aromatic compounds, comprising: (a) a step of producing a monoterpenoid by the method for producing monoterpenoids of the present invention; and (b) a step of converting the monoterpenoid obtained in step (a) into an aromatic compound. In the present invention, the aromatic compound means an aromatic compound produced via an intermediate from a monoterpenoid (for example, methyl perillate). Those skilled in the art can produce aromatic compounds by using monoterpenoids as intermediates according to known methods. In addition, those skilled in the art can appropriately set the production conditions (Esmer Jongedijk, et al., ChemistryOpen 2018, 7, 201-203). Aromatic compounds that can be produced via monoterpenoids as intermediates include, but are not limited to, for example, methyl cumate, cumic acid, terephthalic acid, cumic acid methyl ester, and the like. The methyl perillate produced by the monoterpenoid production method of the present invention can then be converted into cumic acid and further into terephthalic acid by known chemical synthesis reactions (Esmer Jongedijk, et al., ChemistryOpen. 2018 Feb; 7(2): 201-203.).

When the OD600 reached 0.6 to 1.0, IPTG solution was added to a final concentration of 0.1 mM, and cultured with shaking for an additional 24 hours.

[0059] 1 mL of the resulting culture solution was mixed with 1 mL of ethyl acetate using a vortex mixer, and liquid-liquid extraction was performed. 1 μL of the ethyl acetate layer was used for analysis using a gas chromatography mass spectrometer (Shimadzu Corporation GCMS-TQ8040 NX, autosampler AOC-20i Plus). The carrier gas was helium, the column was Agilent HP-5MS (inner diameter 0.25 mm, length 30 m, film thickness 0.5 μm), and the column oven temperature was set to 50 ° C.
