不同氮源对苏云金芽胞杆菌产几丁质酶的影响
Effects of nitrogen sources on the chitinase synthetized by Bacillus thuringiensis
摘要
Abstract
Effects of nitrogen sources on the chitinase synthetized by Bacillus thuringiensis were studied in shake flasks. The results showed that the chitinase activity in LB medium was higher than that in nutrient broth medium, with the highest enzyme activity of 1368.72 and 103.39 U, respectively. The enzyme exhibited higher activity in enzyme production medium added with 1% casein. When adding four lands of amino adds (glutamine, asparagine, praline, methionine), the chitinase activities decreased by 32.5% , 33.7% , 80.6% and 82.6% compared to the control, respectively.关键词
