Fig. 6From: 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 sodium chloride concentration on the production of alkaline proteases by strain HAL1 after incubation for 24 h at 37 °C under shaking conditions (150 rpm). Each value is a mean of three cultures and standard deviations are presented as error bars (n = 3)Back to article page
