Aspergillus nidulans polysaccharide

A mutation in Aspergillus nidulans resulted in loss of both melanin and (1 - 3)-a-D-glucan (a principal cell-wall polysaccharide) and prevented the formation of cleistothecia. " The cell walls of the mutant strain contained more (1 3)-p-... 

An extracellular polysaccharide produced by Aspergillus nidulans is composed of residues of 2-amino-2-deoxy-D-galactose (70%) and o-galactose (15%). A polysaccharide isolated from the ascocarps of Cordyceps sinensis, and containing residues of D-galactose and D-mannose (1 1), has been shown to contain a backbone of (1 - 2)-linked a-D-mannopyranosyl residues with branches composed of (1 3), (1 -> 5)-, and (1 6)-linked D-galactofuranosyl residues...
