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.

For vortex-liquid phase,the E-J relation could be described according to the Kim-Anderson model:U=U0(1-J/JC).While for vortex-glass phase,the electric field decays verydramatically with decreasing current density,so it is difficult to be observed with theinstrument has limited precision.In the intermediate current region,the E-Jrelations of the both phases could be fitted in terms of a phenomenological model:U=(U0/μ)[μ-1],it was concluded that the sign of μ-value changes fromnegative to positive when the temperature decreases lower than the glass-transitiontemperature Tg,meanwhile,the activation energy U enhances dramatically.Whilein the large current region,Zeldov's logarithmic model was suitable for fitthing theE-J curves of the both phase.Moreover,there was no abrupt change of U or thecharacteristic current density IC.However,the effective radius of vortex line variesremarkably around Tg.

It is shown that the reaction U+CO→CUO with a long-lived intermediate complex has no threshold energy, which agrees with the potenlial surface. When the collision energy is greater than 418.4 kJ/mol, the intercharge reaction increases, until the CUO molecule will decompose into U, C, O completely, and these reactions have threshold energy.
