Lipid component, extracted from dried cells of Torulopsis utilis was examined by means of chromatography. It was found that lipid content in dried cells was 3% and this lipid consisted mainly of phospholipid (84%), which was largely composed of lecithin, phosphatidylethanolamine and lysolecithin, however neutral lipids are formed mainly of free fatty acid, triglyceride and sterol.
Analysis of the fatty acid composition of the isolated lipid fractions by gas-liquid chromatography showed that acid neutral lipids and phospholipids contained mainly linoleic acid, oleic acid and palmitic acid, while free fatty acid fraction had a very low content of linoleic acid. The lysolecithin fraction contained considerably larger amounts of linoleic acid than the other lipid fractions.
