Enzymatic activity and stability of endoglucanase A and endo-1,4-beta xylanase. The optimized activity and stability of the recombinant endoglucanase A and endo-1,4-beta Xylanase were determined at different temperatures and pH values. a Effects of pH on the endoglucanase A enzyme activity at 50 °C. b Effects of temperature on the endoglucanase A activity within a temperature range of 20–70 °C, at pH 6.0. c Effects of pH on the endo-1,4-beta xylanase enzyme activity at 50 °C. d Effects of temperature on the endo-1,4-beta xylanase activity within a temperature range of 20–70 °C, at pH 10.0
