Abstract: Protease production by thermophilic Bacillus sp strain SMIA-2 cultivated in liquid cultures containing trisodium citrate reached a maximum in 9h, with levels of 1.93U/mg protein. The microorganism utilized several carbon sources for the production of protease. Starch was the best substrate, followed by trisodium citrate, citric acid and sucrose. Among the various organic and inorganic nitrogen sources, ammonium nitrate was found to be the best. Studies on the protease characterization revealed that the optimum… Show more

“…Protease from a thermophilic Bacillus sp too has exhibited a reduction in enzyme activity at temperatures more than 60°C (16). Lipase produced by a B.licheniformis MTCC 6824 had 45°C as optimum temperature, as reported by Chakraborty and Paul Raj (3).…”

“…During last several years, few haloalkaliphilic bacteria have been studied for their ability to secrete alkaline protease (5,13,16,(26)(27)(28); however, alkaliphilic actinomycetes are relatively less explored in this context.…”

“…Moreover, the activity and stability of this enzyme under extreme conditions of pH and temperature are good characteristics required in biotechnological application of proteolytic enzymes. Though heavy metal ions such as Cu 2+ and Pb 2+ have been reported to inhibit the activity of alkaline protease (NASCIMENTO & MARTINS, 2004), this was not the case for the protease in this study. Our results indicate that this protease may fi nd application in the analytical, leather, and detergent industries.…”
