This study is concerned with the co-production of alkaline proteases and thermostable α-amylase by some feather-degrading Bacillus strains: B. mojavensis A21, B. licheniformis NH1, B. subtilis A26, B. amyloliquefaciens An6 and B. pumilus A1. All strains produced both enzymes, except B. pumilus A1, which did not exhibit amylolytic activity. The best enzyme(More)
An alkaline chymotrypsin from the intestine of striped seabream (Lithognathus mormyrus) was purified by precipitation with ammonium sulfate, Sephadex G-100 gel filtration, Mono Q-Sepharose anion-exchange chromatography, ultrafiltration, second Sephadex G-100 gel filtration, and a second Mono Q-Sepharose anion-exchange chromatography with a 80-fold increase(More)
