α-淀粉酶由几种细菌,真菌和基因改造的微生物种类产生。 α-淀粉酶是一种钙金属酶,即它依赖于金属辅因子对其活性的存在。由于淀粉水解活性和由于水解可以进行的活性,α-淀粉酶已成为至关重要的酶。一种这样的活性是由淀粉生产葡萄糖和果糖糖浆。 α-淀粉酶催化该过程的第一步。以前,淀粉通过酸水解而水解成葡萄糖。 α-淀粉酶可以从植物,动物或微生物中分离。该酶已从大麦和水稻植物中分离出来。已经发现木薯醪废水是α-淀粉酶的来源,其在广泛的pH和温度范围内具有活性[1]。

α-淀粉酶制备

1.中温 α-液化型淀粉酶系用枯草芽孢杆菌（Bacillus Subtilis)经发酵提炼精制而成。

2.采用枯草芽孢杆菌作为生产菌，以玉米粉、黄豆饼粉及无机盐为培养基，经深层培养，发酵液用酒精沉淀或硫酸铵盐析制得。
