摘要
利用紫外线照射法、硫酸二乙酯(DES)法6、0Co-γ射线辐照法对蜡样芽孢杆菌(Bacillus cereus)SKS4进行复合诱变处理,筛选到了1株产异甘露聚糖酶的蜡样芽孢杆菌SKS4360,使其发酵液酶活从1004 U/mL提高到2026.6 U/mL,而且其酶活力表现稳定。
Bacillus cereus strain SKS4 was induced by ultraviolet radiation,DES and ^60Co-γ ray,and a strain SKS4360 with high activity of isomerous mannanase was screened out.The enzyme activity of SKS4360 in the fermentation solution was increased from 1004 U/mL to 2026.6 U/mL,and it was stable in different generations.
