Alkaline proteases from a native bacillus sp alkaline strain

The effect of four nitrogen sources on the enzymatic activity of alkaline proteases, secreted by a native strain of Alkalophilic Bacillus sp, grown at different concentrations of LMF (Fermented Corn Liqueur) was evaluated. The growth of the strain is not affected by the inoculation pH of 7.0; 8.5 an...
