749Mg/ml and 0.778u/ml, respectively. 5. Study on the viscosity changes of reaction solution and analysis of enzymatic hydrolysis products by TLC, HPLC showed that ChiB was an endo-type cleavage enzyme. It decreased viscosity of reaction solution, hydrolyzed β-(1, 4) glucosidic bond of chitosan, acted on GlcN-GlcN, GlcN-GlcNAc and/or GlcNAc-GlcN glucosidic bond. It did not act on GlcNAc-GlcNAc glucosidic bond. Hydrolysis products of chitosan were composed of chitotriose, chitotetraose and chitopentose.
