Figure 5From: Characterization of a new oxidant-stable serine protease isolated by functional metagenomics Effects of various additives on the proteolytic activity of SBcas3.3. SBcas3.3 was pre-incubated at 30°C for 30 min with each additive before activity measurement at pH 9 and 50°C with azocasein as substrate. *p<0.05 (vs control condition). Error bars represent standard errors of the means of triplicate assays.Back to article page
