Polar Lipid Composition in the Classification of Some Actinomadura Species

Abstract
The polar lipids of A. dassonvillei, A. madurae and A. pelletieri were analyzed by 2-dimensional TLC. A. madurae and A. pelletieri had a simple pattern consisting essentially of diphosphatidylglycerol, phosphatidylinositol and monoacyl phosphatidylinositol dimannoside, but A. dassonvillei strains contained diphosphatidylglycerol, phosphatidylglycerol, a lipid which co-chromatographed with phosphatidylcholine and a chromatographically mobile unknown phospholipid. Two A. dassonvillei strains had substantial proportions of uncharacterized glycolipids and phosphoglycolipids. Low proportions of lipids co-chromatographing with, and having the same staining reactions as, phosphatidylethanolamine, phosphatidylinositol and diacyl phosphatidylinositol dimannoside were detected in several strains of A. dassonvillei.
