蚕蛹壳几丁质降解菌的分离筛选及其产酶条件优化
Isolation and Screening of Silkworm Puparium Chitin Degradation Strains and the Optimization of Chitinase-produce Conditions
摘要
Abstract
[Objective] The aim of this study was to optimize the conditions of chitinase-produce strains. [ Method] A kind of screened chitinase-produce strain G-254 was habituated cultured, and then the single factor experiment was carried out to explore the effects of different carbon source, nitrogen source and inorganic salt on the activity of produced chitinase; the response surface test was used to determine the optimal conditions for chitinase production. [ Result] The optimal conditions for chitinase production were: 8% of glucose, 5% of beef extract and 0.07% of MgSO4, and the activity of chitinase reached the maximal value (6.86 U) under these conditions. [ Conclusion ] The study improved the activity of chitinase produced by strain G-254 and provided good foundation for industrial production.关键词
