Effect of substrate specificity on the chitosanase activity^a

Substrate	Relative activity (%)
Colloidal chitosanb	100
Glycol chitosanc	113
Flaked chitosand	35
Carboxymethylchitosan	6
Colloidal chitin	0
Ethyleneglycol chitin	0
Carboxymethyl chitin	0
Cellulose	0

^aRelative activity determined with colloidal chitosan is indicated as the standard. Chitosan and chitin-related compounds were used as the substrates of purified enzyme. 

^b80% deacetylated chitosan was used. 

^c90% deacetylated chitosan was used. 

^d100% deacetylated chitosan was used.
