Abstract: A protease from a new isolate of Bacillus sp. APR-4 with optimum activity at pH 9.0 and 65-70°C was found stable in 5% detergents (Farishta®, Fena®) at 50°C and also in 500 mg/l of sodium hypochlorite. It retained 78% activity even after 24 hrs of incubation with detergents (Farishta®, Fena®) at 30°C. The protein stains (egg yolk) were removed within 10 min from test fabric (cotton) in 100 U/ml enzyme at pH 9.0 with 1% detergent (Farishta®) and it took 30 min to remove blood stains with 100 U/ml enzyme only.
