γ-环状糊精葡萄糖基转移酶产生菌32-3-10产酶条件及酶促反应条件的研究

Studes on γ-CGTase from Bacillus 32-3-10

筛选到一株芽胞杆菌 32 - 3- 10 ,它所产γ -环状糊精葡萄糖基转移酶可以淀粉为底物生成γ -环状糊精 ,对其产酶条件及酶促反应条件进行了研究。

A strain of bacterium which could produce enzyme(γ-CGTase) forming γ-cyclodextrin(γ-CD) was isolated from soil in Xinjing province. The enzyme could act on starch to produce cyclodextrins(CD),with a proportion of α-CD∶β-CD∶γ-CD=46∶5∶49.
