Production of alkaline proteinase by a new bacterial strain, Bacillus PE-11

A new strain of Bacillus sp., Bacillus PE-11 isolated and identified in our laboratory was found to be a potential producer of alkaline proteinase. The production of proteinase was studied in thirteen different reported media to select the optimal production medium. In all the reported media, the medium XII of composition: glucose, 0.2%; peptone, 1.5%; salt solution, 5% (MgSO4. 7H2O, 0.5%; KH2PO4, 0.5%; FeSO4. 7H2O, 0.01%; distilled water make up to 100 ml.) is found to have the highest inducing effect on enzyme production.
