| 1. A method of recovering arachidonic acid-containing lipids, comprising
culturing microorganisms of the genus Mortierella sect. schmuckeri in a fermentation medium,
harvesting the microorganisms,
recovering lipids from the microorganisms, and
removing impurities from the recovered lipids, whereby arachidonic acid-containing lipids are recovered; wherein said Mortierella sect. schmuckeri produces at least about 0.70 grams of arachidonic acid per liter per day when grown under appropriate fermentation conditions.
