Studies on the cell wall of Schizophyllum commune. Permethylation and enzymic hydrolysis.

Two polysaccharide fractions S-glucan were isolated from the cell walls of Schizophyllumcommune. S-Glucan is primarily a linear 1,3-alpha-glucan with occasional 1,6-alphalinkages as shown by permethylation and partial acid hydrolysis. The glucan fraction also contains a small amount of xylose. The R-glucan fraction is a mixture of two polysaccharides, chitin and a highly branched glucan with linear 1,6-beta and 1,3-beta segments and 1,6-beta branching. This conclusion is based on permethylation studies and enzymic hydrolyses.
