Studies on the Structure of Polysaccharide from Trichophyton mentagrophytes

Abstract

An alkali-soluble polysaccharide, designated as S-Iaw, has been isolated from the mycelia of Trichophyton mentagrophytes. It gave a single peak on high-speed liquid chromatography. The only component sugar was D-mannose, and its molecular weight was found to be about 24000. Methylation, periodate oxidation, and acetolysis studies suggested that S-Iaw is composed of repeating units of O-(2-O-α-D-mannopyranosyl)-6-O-α-D-mannopyranosyl-α-D-mannopyranose.
