The purified recombinant enzyme had optimal reaction conditions at pH 5.0 and 80 °C, was stable between pH 4.0 and pH 6.0. The enzyme had residual activity of 60% at 95 °C for 6 h at pH 5.0, thus has considerable potential in industrial applications. The specific activities of the enzyme to salicin, p-Nitrophenyl β-D-glucopyranoside, p-nitrophenyl β-D-xylopyranoside and p-nitrophenyl α-D-glucopyranoside were: 57500 U/mg, 1632 U/mg, 109 U/mg, and 39 U/mg, respectively, the specificity of salicin was the highest, p-nitrophenyl β-D-glucopyranoside followed, no activities to xylan and arabinofuranoside.
