摘要
从土壤样本中分离出一株产α-淀粉酶的菌株,经形态学初步鉴定为热红短芽孢杆菌。对该菌株产酶条件进行了优化,确定其最佳碳源为麸皮,最佳氮源为明胶,最佳p H值为10,最佳初始装液量为60 m L。
Anα-amylase-producing strain was screened and isolated from soil samples. The strain was prelimi-narily identified as B.thermonber by morphologic taxonomy. The lipase fermentation condition for the strain was optimized by studying on effect of nitrogen sources ,carbon sources and other influence factors. The optimum carbon and nitrogen source was bran and gelatin. The optimum pH was 10 and the best amount was 60 mL.
