The mode of degradation of glycol chitin and chitin by two enzyme fractions separated from Aspergillus niger was investigated. One of the enzyme rapidly cleaved the endo-β-glucosaminidic bonds in the polysaccharide chain, forming chitodextrin and oligosac-charides, while the other produced monosaccharide as a main product in the degradation. The successive action of the two enzymes was also examined. Intermediate products in the enzymatic degradation were surveyed using paper and column chromatography. Also, the over-all pattern of degradation of glycol chitin and chitin by the chitinase system of Aspergillus niger was discussed.
