The Comparison of the Effect of the Depolymerization of Chitosan by Four Enzymes

ZHOU Sun ying 1,YU Ping 2,CHEN Sheng 2,LI Zhu lai 1 (1 The pharmacology department of Fujian Midical University,Fuzhou 350004;2 Boichemistry lab, Int of Polym, Fujian Teachers Univ, Fuzhou 350007)  
OBJECTIVE To compare the effect of the depolymerization of chitosan by enzymes including lipase, lysozyme, cellulase, pepsin METHODS By derteming the reducing sugar concentration in chitosan solution, the optimum condition for enzymatic hydrolysis of chitosan were investigated and the hydrolytic velocity of chitosan by four enzymes were evaluated RESULTS The hydrolysis rate of pepsin was the fastest and that of lysozyme was the slowest CONCLUSION By degrating chitosan, the most effective enzyme was pepsin among four anzymes
