A lipoteichoic acid and a membrane glycolipid were isolated from Bacillus licheniformis 6346 MH-1. The fatty acid composition of the two preparations were similar. Most of the fatty acids were of the branched chain type. The glycolipid was shown to be a diacyl derivative of O-beta-D-glucopyranosyl-(1 leads to 6)-O-beta-D-glucopyranosyl-(1 leads to 3)-glycerol. The lipoteichoic acid contained lipid, polyglycerol phosphate, and glucosamine. The lipid was released by treatment with hydrofluoric acid and by hydrolysis in dilute acid and was shown to have a structure identical with that of the membrane glycolipid.
