Title:
HIGHLY UNSATURATED FATTY ACID AND PRODUCTION OF LIPID CONTAINING THE ACID
Document Type and Number:
Japanese Patent JP3354608
Kind Code:
B2
Abstract:
PURPOSE: To produce a highly unsaturated fatty acid and a lipid containing the acid in high efficiency by using a microbial strain belonging to the subgenus Mortierella, genus Mortierella.
CONSTITUTION: A highly unsaturated fatty acid and a lipid containing the acid are produced by the aerobic culture of a microbial strain belonging to the subgenus Mortierella, genus Mortierella in a liquid medium. In the above process, the dissolved oxygen concentration in the culture liquid is maintained to 5-28ppm. The production of the highly unsaturated fatty acid is increased to about 1.2-1.8 times by the use of the oxygen-feeding condition of the present invention compared with conventional fermentation condition.
