Abstract

In the present study, alkaline protease producing thermophilic Bacillus cohniiU3 strain was isolation from Unnai hot spring, India. The maximum production of protease (344 U/mL) was reported after 72 h of inoculation at 50°C in shake flask culture using the gelatin casein medium. The protease was found to remain active up to 96 h and production was growth dependent. The activity of parital purified protease was reported in abroad range of pH ranging from 4.0 to 11.0 with an optimum of 9.0 pH; Enzymes was indicated the highest activity at 50°C temperature. Salt independent catalysis and activity with a broad range of substrate concentration is the key feature of the protease. Thermos table nature, the stability in alkaline pH and stability in high salt concentration for 45 min were outstanding features of protease. The enzyme was stable in the presence of various organic solvents like Dimethyl Sulphoxide (DMSO), Methanol, Butanol, n-Hexane, Benzene at 25% (v/v) concentration. A good compatibility of the enzyme with most commercial detergents indicated its application in detergent industry. The remarkable dehairing in goat hide and destaining of blood spot in 2 h using 10 U/mL of protease assure that it could be a potential candidate for leather and detergent industries.
