Effect of: a) nitrogen and b) carbon (0.5% m/V) sources, and c) amounts of NaCl on the activity of protease from Bacillus luteus H11. The study was evaluated by incubating bacterial culture for 72 h under optimal growth conditions: 30 °C, pH=9, and 5% NaCl (a and b), 30 °C and pH=9 (c). Each value represents mean±S.D., N=3
