Effects of temperature and pH on the β-glucosidases D2-BGL and Novozyme 188 (N188). D2-BGL and N188 retained more than 80% of enzyme activity after 4-h incubation at 55 °C (a), and the optimal temperature was 70 °C (b). Relative activity remained > 80% at pH 4–8 after 24-h incubation at 4 °C (c), and the optimal pH was < 5 (d). Enzyme assays were performed in triplicate with pNPG as substrate, and error bars represent the standard deviation
