PURPOSE:To obtain a large amount of the titled lipid component in high safety, from which gamma-linolenic acid is isolated and purified easily, by cultivating a mold belonging to the genus Thamnidium, capable of producing lipid having high gamma- linolenic content in a medium having a high carbon content, collecting the component from the culture. CONSTITUTION:A mold (preferably Thamnidium elegans) belonging to the genus Thamnidium, capable of producing lipid having high gamma-linolenic acid content, is cultivated in a medium (preferably 3-30wt% liquid medium of organic carbon source) having high carbon source concentration at preferably a slightly acidic - neutral pH at 15-30 deg.C for 4-15 days, and the aimed lipid is obtained from the mold. gamma-Linolenic acid content is >=20wt% based on fatty acid composition.
