摘要：

The present study is concerned with the selection of economically available agricultural starchy substrate for the production of alpha amylase by Bacillus licheniformis. Different agricultural starchy substrates such as soluble starch, hordium, pearl millet, rice, corn, gram and wheat starch were tested for the production of alpha amylase by parental and its mutant derivatives. The production of alpha amylase was 10-folds better by the mutant strain B. licheniformis GCUCM-30 than the parental strain when pearl millet starch at 1.5% level and nutrient broth concentrations at the level of 0.25% was supplemented to the fermentation medium.
