Abstract

The composition of cell membranes and mycelia ofStreptomyces levoris, producer of the polyene antibiotic levorin, was studied. The membrane protein/lipid ratio was shown to be constant during growth of the microorganism. The membrane protein was found to be heterogeneous and to have a low molecular weight. The lipid component of the membranes consisted mainly of polar lipids—phosphatidyl ethanolamine, diphosphatidyl glycerol, and phosphatidyl inositol mannoside being predominant. During growth, the phospholipid content of the polar lipid fraction decreased, apparently due to replacement of phospholipids by phosphorus-free analogs.
