Isolation of a Water-soluble Polysaccharide from the Mycelium of Penicillium chrysogenum (Studies on Fungal Polysaccharides. V)

Abstract

Main water-soluble intracellular polysaccharide of P. chrysogenum is a galactomannan consists of D-galactose and D-mannose in an approximate ratio of 2 : 3 with trace of D-glucose. Assay of formic acid and formaldehyde released by periodate oxidation and that of Smith type degradation products showed that the polysaccharide has a linear structure and contains 1→2 main linkage with 1→3 linkage also 1→4 linked galactopyranose or 1→5 or 1→6 linked galactofuranose residue.
