Isolation and identification of galactosyl glucosyl diglyceride from saccharopolyspora hirsuta

The major glycolipid component from saccharopolyspora hirsute [N626] was isolated and investigated. Acid hydrolysis of the isolated lipid yielded, glucose, galactose, glycerol and a mixture of fatty acids. Analysis of the latter by gaschromatography showed that they consisted largely of palmitic, stearic and oleic acids
