Figure 2. ii).
Temperature and pH effects on endoglucanase, β-glucosidase and xylanase of Bacillus licheniformis JK7 activity (A and C) their stability (B and D). Enzyme activity of the culture supernatants was determined at 24 h. All assays were performed in triplicate. The data points and error bars indicate the average values and standard errors. a,b,c,d,e,f,g Indicates a significantly (p<0.05) different activity influenced by temperature or pH in the same enzyme group. x,y,z Indicates a significantly (p<0.05) different activity between different enzymes within same temperature or pH. 1 NS means not significant.
