Process for production of fatty acids having high degree of unsaturation.

摘要

A process for the production of a mixture of highly unsaturated fatty acids comprising the steps of (1) culturing a microorganism belonging to the genus Mortierella and capable of synthesizing highly unsaturated fatty acids, (2) preparing intact cells or products derived from the cells having an ability to synthesize highly unsaturated fatty acids from a precursor thereof, (3) converting the precursor to the highly unsaturated fatty acids in the presence of the intact cells or a product derived from the cells to obtain a reaction mixturecontaining the highly unsatured fatty acids, and (4) recovering a mixture of the highly unsaturated fatty acids from the reaction mixture; and a process for the production of a highly unsaturated fatty acid comprising the steps of (1) culturing a microorganism belonging to the genus Mortierella and capable of synthesizing highly unsaturated fatty acids, (2) preparing intact cells or products derived from the cells having an ability to synthesize highly unsaturated fatty acids from a precursor thereof, (3) converting the precursor to the highly unsaturated fatty acids in the presence of the intact cells or a product derived from the cells to obtain a reaction mixture, (4) recovering a mixture of the highly unsaturated fatty acids from the reaction mixture containing the highly unsatured fatty acids, and (5) isolating an individual highly unsaturated fatty acid.
