DIHOMO-GAMMA-LINOLENIC ACID-CONTAINING MICROBIAL OIL AND DIHOMO-GAMMA-LINOLENIC ACID-CONTAINING MICROBIAL BIOMASS

摘要

A microbial oil comprising dihomo-?-linolenic acid as a constituent fatty acid of an oil, the microbial oil has a content, in terms of a weight ratio of arachidonic acid relative to dihomo-?-linolenic acid (arachidonic acid/dihomo-?-linolenic acid) of less than 1/13. Preferably, the microbial oil has a triglyceride content of greater than or equal to 70% by weight, and a saturated fatty acid content of less than or equal to 40% by weight. Moreover, a lower alcohol ester of dihomo-?-linolenic acid or a free fatty acid of dihomo-?-linolenic acid obtained from the microbial oil is provided.
