The effect of temperature and pH on recombinant β-xylosidase. (A) The optimal temperature was measured in 50 mM sodium phosphate buffer (pH 6.0) in the presence of 1 mM PNPX at various temperatures for 15 minutes. (B) The optimum pH was determined by incubating at 50°C for 15 minutes in the presence of 2 mM PNPX in sodium phosphate buffer varying pH.
