摘要:
A process for the production of 8,11-eicosadienoic acid or a lipid containing 8,11-eicosadienoic acid comprising the steps of, culturing a microorganism having an ability to produce an omega 9 type polyunsaturated fatty acid in a medium supplemented with a .DELTA.5 desaturase inhibitor, or adding a .DELTA.5 desaturase inhibitor to a medium in which said microorganism has been cultured and further culturing the microorganism to produce 8,11-eicosadienoic acid, or a lipid containing 8,11-eicosadienoic acid, and recovering the 8,11-eicosadienoic acid, or the lipid containing 8,11-eicosadienoic acid.

摘要:
A method of breeding a lipid-producing strain belonging to the genus Mortierella. According to the method of breeding a lipid-producing strain which involves an expression-inhibiting step of inhibiting the expression of a specific gene in the lipid-producing strain as described above, a lipid-producing strain belonging to the genus Mortierella can be efficiently and effectively bred.
摘要:
There are provided microorganisms having a property of producing a lipid containing unsaturated fatty acids as constituent fatty acids and extracellularly secreting the produced lipid encapsulated in lipid vesicles, methods of screening said microorganisms, as well as methods of efficiently producing a fatty acid-containing lipid using said microorganisms. Furthermore, there are provided lipid vesicles encapsulating a lipid containing unsaturated fatty acids, and foods, cosmetics, and animal feeds comprising said lipid vesicles added thereto. Artificially treated microorganisms or microorganisms collected from nature are grown on a solid medium, and microbial strains that form lipid vesicles at the periphery of the colonies and/or microbial strains that, when cultured in a transparent liquid medium, make the culture liquid cloudy are selected. The microorganisms obtained are cultured, lipid-containing lipid vesicles secreted in the culture liquid, are separated from the culture liquid, and the lipid is separated and purified.
摘要:
The present invention discloses a process for producing lipid containing omega-9 highly unsaturated fatty acid by culturing in a medium a mutant strain obtained by mutation on a microorganism having the ability to produce arachidonic acid belonging to the genus Mortierella and so forth, in which .DELTA.12 desaturation activity is decreased or lost, but at least one of .DELTA.5 desaturation activity, .DELTA.6 desaturation activity and chain length elongation activity is elevated. Moreover, the present invention also discloses a process for producing omega-9 highly unsaturated fatty acid by collecting omega-9 highly unsaturated fatty acid from the culture or lipid described above.
