Examination of the lipids of three species of nonphotosynthetic bacteria with extensive internal membranes revealed phosphatidyl choline (lecithin) in two species. In one of these there was an unusual accumulation of phosphatidyl N-dimethylethanolamine. (The relation between lecithin and membrane elaboration in microorganisms is discussed.)
