Figure 6From: Optimization of physical factors affecting the production of thermo-stable organic solvent-tolerant protease from a newly isolated halo tolerant Bacillus subtilis strain RandEffect of agitation rate on protease production. Culture media were incubated at 37°C with different shaking rates (0, 50, 100, 150, 200 and 250 rpm) for 24 h. Protease activity at 200 rpm was considered as 100%.Back to article page
