Abstract
The cell of Fusarium oxysporum was digested with commercial Bacillus chitosanase. The chitosanase produced low molecular weight heterooligosaccharides consisting of GlcN and GlcNAc from the cell wall. A main component of the digestion products was identified as 2-amino-2-deoxy-beta-D-glucopyranosyl- (1-->4)-2-acetamido-2-deoxy-D-glucopyranose. The chitosanase appeared to be more effective than Streptomyces griseus chitinase for cell wall digestion. Moreover, maltose was unexpectedly found in the digestion products, indicating that the cell wall contains alpha-1,4-linked glucan chain as a polysaccharide component.Keywords
