This work reports the production of a novel alkaline protease from the fungus Aspergillus niger. The protease was purified from the culture supernatant to homogeneity using ammonium sulfate precipitation, Sephadex G-150 gel filtration and DEAE-sepharose ion exchange chromatography with a 13.9-fold increase in specific activity. The molecular weight of the enzyme was estimated to be 32 kDa on SD...
