Abstract: | Abstract A lipoglycan has been extracted from cells of Propionibacterium freudenreichii by the standard procedures used to isolate lipoteichoic acids from Gram-positive bacteria. The polymer was purified by chromatography and shown to contain mannose, inositol, glycerol, fatty acids and phosphate. The presence of the components of phosphatidylinositol suggests the lipoglycan may be a mannan anchored to the membrane by a covalently linked phosphatidylinositol although alternative structures cannot be excluded. |
