Fig. 14From: Optimization, partial purification, and characterization of a novel high molecular weight alkaline protease produced by Halobacillus sp. HAL1 using fish wastes as a substrateEffect of pH on the activity of HAL1 protease. The effect of pH was evaluated by assaying protease activity at different pH between 4 and 11. The error bars show the standard deviation of three replicatesBack to article page
