Exemplary embodiments provided herein include genetically engineering microorganisms, such as yeast or bacteria, to produce cannabinoids by inserting genes that produce the appropriate enzymes for the metabolic production of a desired compound.

The invention provides non-naturally occurring microbial organisms containing a fatty alcohol, fatty aldehyde or fatty acid pathway, wherein the microbial organisms selectively produce a fatty alcohol, fatty aldehyde or fatty acid of a specified length. Also provided are non-naturally occurring microbial organisms having a fatty alcohol, fatty aldehyde or fatty acid pathway, wherein the microbial organisms further include an acetyl-CoA pathway. In some aspects, the microbial organisms of the invention have select gene disruptions or enzyme attenuations that increase production of fatty alcohols, fatty aldehydes or fatty acids. The invention additionally provides methods of using the above microbial organisms to produce a fatty alcohol, a fatty aldehyde or a fatty acid.

Described is a method for the production of isobutene from 3-methylcrotonyl-CoA comprising the steps of: (a) enzymatically converting 3-methylcrotonyl-CoA into 3-methylbutyric acid; and (b) further enzymatically converting the thus produced 3-methylbutyric acid into isobutene.

The conversion of 3-methylcrotonyl-CoA into 3-methylbutyric acid can be achieved by first enzymatically converting 3-methylcrotonyl-CoA into 3-methyl butyryl-CoA and further enzymatically converting the thus produced 3-methylbutyryl-CoA into 3-methylbutyric acid. Alternatively, the conversion of 3-methylcrotonyl-CoA into 3-methylbutyric acid can be achieved by first enzymatically converting 3-methylcrotonyl-CoA into 3-methylcrotonic acid and then further enzymatically converting the thus produced 3-methylcrotonic acid into 3-methylbutyric acid.

Exemplary embodiments provided herein include genetically engineering microorganisms, such as yeast or bacteria, to produce cannabinoids by inserting genes that produce the appropriate enzymes for the metabolic production of a desired compound.

Provided herein are methods, compositions, and non-naturally occurring microbial organism for preparing compounds such as1-butanol, butyric acid, succinic acid, 1,4-butanediol, 1-pentanol, pentanoic acid, glutaric acid, 1,5-pentanediol, 1-hexanol, hexanoic acid, adipic acid, 1,6-hexanediol, 6-hydroxy hexanoic acid, ?-Caprolactone, 6-amino-hexanoic acid, ?-Caprolactam, hexamethylenediamine, linear fatty acids and linear fatty alcohols that are between 7-25 carbons long, linear alkanes and linear ?-alkenes that are between 6-24 carbons long, sebacic acid and dodecanedioic acid comprising: a) converting a C.sub.N aldehyde and pyruvate to a C.sub.N+3 ?-hydroxyketone intermediate through an aldol addition; and b) converting the C.sub.N+3 ?-hydroxyketone intermediate to the compounds through enzymatic steps, or a combination of enzymatic and chemical steps.

Microorganisms are genetically engineered to continuously produce fatty acids, fatty alcohols, cultured protein, or any combination thereof by microbial fermentation, particularly by microbial fermentation of a gaseous substrate. The microorganisms are C1-fixing. The production of fatty acids, fatty alcohols, and cultured proteins can be improved. This can be improved by varying promoters or nutrient limiting means.

The present invention relates to a recombinant organism or microorganism having a decreased pool of crotonic acid compared to the organism or microorganism from which it is derived due to at least one of: (i) an increased conversion of crotonyl-CoA into butyryl-CoA; and/or an increased conversion of butyryl-CoA into butyric acid; (ii) an increased conversion of crotonyl-CoA into 3-hydroxybutyryl-CoA; and/or an increased conversion of 3-hydroxybutyryl-CoA into 3-hydroxybutyric acid; (iii) an increased conversion of crotonic acid into crotonyl-CoA; (iv) an increased conversion of crotonyl-[acyl-carrier protein] into butyryl [acyl-carrier-protein]; (v) a decreased conversion of crotonyl-CoA into crotonic acid; and/or (vi) a decreased conversion of crotonyl-[acyl-carrier protein] into crotonic acid. Moreover, the present invention relates to the use of such a recombinant organism or microorganism for the production of alkenes with the enzyme ferulic acid decarboxylase. Further, the present invention relates to a method for the production of isobutene or butadiene by culturing such a recombinant organism or microorganism in a suitable culture medium under suitable conditions.

Microorganisms are genetically engineered to continuously produce fatty acids, fatty alcohols, cultured protein, or any combination thereof by microbial fermentation, particularly by microbial fermentation of a gaseous substrate. The microorganisms are C1-fixing. The production of fatty acids, fatty alcohols, and cultured proteins can be improved. This can be improved through the expression of 3-hydroxyacyl-ACP:CoA transacylases.
