MATERIALS AND METHODS
Isolation and Screening of Microorganisms producing Proteases
The soil samples were collected from Maharani Science College Campus Bangalore, were
diluted in sterile saline solution. The diluted samples were plated onto Gelatin agar plates
containing peptone (0.1% wt/vol), NaCl (0.5% wt/vol), agar (2.0% wt/vol), and gelatin (10%
vol/vol) pH-7.0. Plates were incubated at 37 °C for 24 hours. A clear zone of gelatin hydrolysis
gave an indication of protease producing organisms. Depending upon the zone of clearance, the
strain SNR01 was selected for further experimental studies. The isolated proteolytic strain was a
spore-forming gram-positive rod, identified as Bacilllus sp by slandered biochemical tests[14,15]
