[Lipid composition of Acholeplasma laidlawii cells]

Lipid composition of the cells of Acholeplasma laidlawii was studied by column and thin layer chromatography. Lipids of the cells contain phospholipids (41.3%), glycolipids (28%) and neutral lipids. Phospholipids are represented by monoacylglycerophosphoryldiglucosyldiglyceride, glycerophosphoryldiglucosyldiglyceride, phosphatidylglycerine and phosphatidic acid. Glycolipids contained diglucosyldiglyceride and monoglucosyldiglyceride. The content of cholesterine was low (1.3%) while the content of carotenoids was A442X1000/mg lipids -- 150. Lipid components of Acholeplasma laidlawii and related strains of A. laidlawii A and B are compared.
