Sugar-containing lipids in the classification of representative Actinomadura and Nocardiopsis species.

The major sugar-containing lipids of some Actinomadura and Nocardiopis strains--recognized as an important agent of actinomycetoma -- were analyzed by thin-layer and gas-liquid chromatography. It was demonstrated that Nocardiopsis dassonvillei strains contained two characteristic glycolipids identified as monomannosyl diglyceride and monoacylated glucose. None of them was found in the representatives of Actinomadura madurae and Actinomadura pelletieri strains, which possessed phosphatidylinositol-mannosides as major sugar-containing lipids. The glycolipids of Nocardiopsis dassonvillei seem to be of value in the taxonomy. In connection with this a simple glycolipid patterns of these microorganisms, established by TLC, was presented.
