Study of optimum condition for alkaline protease production from local isolate of Aspergillus niger

الملخص EN

Extracellular alkaline protease production by Aspergillus niger was studied with the presence of different carbon and nitrogen sources availability in batch culture condition.A.

niger showed better protease production in the presence of organic nitrogen sources compare to inorganic nitrogen sources in the medium, which consist of 1 % glucose as carbon source, 1.5 % casein hydrolysate as nitrogen source and 1 % Nacl at initial pH = 10 on rotary shaker incubator 140 rpm at 40 º C for 5 days.
