The present invention relates to a method for producing a medium chain diamine and, more specifically, to a method for producing a medium chain diamine from an alcohol or alkane derived from a fatty acid, by culturing a recombinant microorganism from which a fatty aldehyde dehydrogenase gene in a ω-oxidative metabolic pathway and a β-oxidative metabolic pathway related gene have been deleted, and also into which a ω-transaminase gene has been introduced. The recombinant microorganism disclosed in the present invention can prevent the additional oxidation and β-oxidation metabolism of fatty aldehyde and can produce a medium chain diamine with a high yield by introducing an amine group to the terminus thereof.

The present invention relates to pheromone production, desaturated fatty alcohols or aldehydes or acetates using recombinant yeasts expressing acyl-CoA oxidase to shorten fatty acyl-CoA by two carbons, deleting endogenous acyl-CoA oxidase, express desaturase to introduce at least one double bond, acyl-CoA-reductase to convert fatty acyl-CoA into fatty alcohol. Further, acetyltransferase can be used to convert to desaturated acyl fatty acetate, alcohol dehydrogenase or fatty acyl oxidase to convert to desaturated fatty aldehyde.

A process of producing methacrylic acid and/or derivatives thereof including the following steps: (a) biologically converting isobutyryl-CoA into methacrylyl-CoA by the action of an oxidase; and (b) converting methacrylyl-CoA into methacrylic acid and/or derivatives thereof. The invention also extends to microorganisms adapted to conduct the steps of the process.

The present invention relates to a long-chain dibasic acid with low content of long-chain dibasic acid impurity of shorter carbon chain, to the preparation of a long-chain dibasic acid producing strain by directed evolution of POX gene and homologous recombination, and to the production of a long-chain dibasic acid with low content of long-chain dibasic acid impurity of shorter carbon chain by using the strain. The present invention also relates to a strain containing a mutated promoter, wherein, when a long-chain dibasic acid is produced by fermentation of this strain, the content of the acid impurity of shorter carbon chain in the fermentation product is significantly reduced.

Strains of yeasts are provided containing the genes for the production of cannabinoids from fatty acids. The enzymes that mediate cannabinoid production are localized to the cytosol, peroxisome or different compartments within the secretory pathway (e.g., endoplasmic reticulum, Golgi, vacuole) to ensure efficient production. The engineered microorganisms produce cannabinoids in a controlled fermentation process.

The present invention provides a mutant algal microorganism that has a mutation that causes attenuated expression of TrifuncB and/or TrifuncA and as a result produces more lipids than a control algal microorganism. The mutant algal microorganism can further include a mutation in a gene encoding a peroxisomal beta-oxidation pathway protein, such as an ACO1 or PXA1 gene, or a glyoxylate pathway protein, such as an ICL1 gene, that results in attenuated expression and further increased lipid production. Furthermore, provided herein are methods of producing lipids using the mutant algal microorganisms and methods of making the mutant microorganisms.

The present invention provides for a genetically modified host cell or bacterium capable of producing an organic molecule, wherein the bacterium is capable of using hydrogen sulfide as an electron donor, carbon dioxide (CO.sub.2) as a carbon source, and/or nitrate as an electron acceptor. The present invention is useful in the wastewater treatment industry, in particular in municipal wastewater treatment plants (WWTP).

The present invention relates to a method for producing dioic acids from a substrate containing hydrocarbons or fatty acids using a Candida infanticola strain, and to a Candida infanticola microorganism used therefor. The present invention reduces the cost increase resulting from the fluctuation in the international oil price and the burden of environmental pollution, which are caused by the use of fossil fuels, and thus can be utilized in various industrial fields using DDDA as a raw material.
