摘要
试验对从淀粉厂附近的土壤中筛选的产耐酸性α-淀粉酶的菌株发酵条件进行了考察,确定最佳发酵条件为pH4.5、碳源为可溶性淀粉、氮源为柠檬酸二氢铵、培养温度为35℃、接种量为2 mL。
Fermentative condition of the acid resistant alpha-amylase producing strain which was isolated from the soil sample was studied, the optimum conditions are as fallows., pH is 4.5,carbon resource is soluble starch, nitrogen resource is dihydroammonium citrate, culturing temperature is 35 ℃ ,inoculation quantum is 2 mL.
