Studies on α-amylase formation by <i>Bacillus subtilis</i>

Abstract

The synthesis of cx-amylase (x-1,4-glucan 4-gluc- anhydrolase, EC 3.2.1.1) by cultures of BacilUqm 8ubtil8 has been studied by several groups of workers, who have defined the basic conditions required for the formation of high yields of the enzyme (Hagihara, 1951, 1954; Fukumoto, Yama- moto, Tsuru & Ichikawa, 1957b; Fukumoto, Yamamoto & Tsuru, 1957a). For oc-amylase pro- duction a carbohydrate source is required and this
