## Abstract The effect of some medium components, viscous substances and metabolic inhibitors, on catalase production by mutant __Aspergillus niger__ has been studied in shake culture. Altering the composition of the basal medium, particularly substituting NaNO~3~ for KNO~3~, and peptone for yeast
In the present study, the extracellular protease activity in a strain of the filamentous fungus Aspergillus niger was investigated and mutant strains deficient in the production of extracellular proteases were isolated. The major protease, which is responsible for 80-85% of the total activity, is as
