Abstract
A bacterial strain was isolated from dhal industry red gram waste and identified as Bacillus. A thermostable extracellular amylase was partially purified from the strain. Optimum temperature and pH for the enzyme were found to be 60 degrees C and 6.5, respectively. The maximum amylase production was achieved with maltose as carbon source. Among the nitrogen sources, peptone and yeast extract produced maximum amylase.
摘要
从木豆加工业的红芸豆废料中分离出一株细菌菌株，并鉴定为芽孢杆菌属。从该菌株中部分纯化出一种耐热性胞外淀粉酶。发现该酶的最适温度和pH分别为60℃和6.5。以麦芽糖作为碳源时淀粉酶产量最高。在氮源中，蛋白胨和酵母提取物产生的淀粉酶最多。
