The enzymatic characteristics of CDW-xyl-8 and CDW-xyl-16. A The optimal temperature of CDW-xyl-8; B The optimal pH of CDW-xyl-8; C The optimal temperature of CDW-xyl-16; D The optimal pH of CDW-xyl-16. The pH conditions of the dark grey data dots were provided by disodium phosphate–citrate buffer (200 mM, pH 3.0–6.0), the pH conditions of the red data dots were provided by Tris–HCl buffer (100 mM, pH 6.0–9.0), and the pH conditions of the blue data dots were provided by glycine–NaOH buffer (100 mM, pH 9.0–10.0) in B and D. The values represent the mean values of triplicate experiments, and the error bar indicates the standard deviation
