Oil and fat content ones or dokosahekisaen acid content ratio in the oil and fat the method of increasing

摘要

Topic: Offer the oil and fat where dokosahekisaen acid content ratio increases.Solution expedient: sutoramenopairu possessing highly unsaturated fatty acid production talent, it features that it cultures with the nutrient medium which contains the substance which obstructs the fatty acid unsaturated conversion enzyme, the highly unsaturated fatty acid which is obtained by the production method and the said method of the highly unsaturated fatty acid, the oil and fat where especially dokosahekisaen acid content ratio increases. sutoramenopairu, it features that it cultures with the nutrient medium which contains the substance which obstructs the fatty acid unsaturated conversion enzyme, sutoramenopairu where the highly unsaturated fatty acid production talent which is obtained by the reinforcement method and the said method of highly unsaturated fatty acid production talent of sutoramenopairu was reinforced. Especially, it is the microbe where said sutoramenopairu is classified into the rabirinchiyura cord, production method of the said highly unsaturated fatty acid, reinforcement method of the said highly unsaturated fatty acid production talent, and sutoramenopairu where the said highly unsaturated fatty acid production talent was reinforced.
