Veratryl alcohol could stimulate the oxidation of PR catalyzed by LiP, especially at higher molar ratios of H2O2 to PR, however, PR inhibited the LiP catalyzed oxidation of VA.

藜芦醇对LiP催化氧化PR的反应有促进作用，尤其是当H202与PR的摩尔比较高时这种促进作用更为明显；然而PR对LiP催化氧化VA的反应却有抑制作用。

The steady state kinetics of the lignin peroxidase catalyzed oxidation of veratryl alcohol by H2O2 in a sodium bis(2-ethylhexyl) sulfosuccinate/isooctane/toluene/water reverse micellar medium was studied and a comparison with the corresponding aqueous medium was made to understand the effect of the reverse micellar medium on the catalytic mechanism and kinetic parameters.

为了理解木素过氧化物酶在反胶束介质中的催化性能与动力学行为，本文以LiP催化过氧化氢氧化藜芦醇反应为模型反应，研究了2-乙基己基琥珀酸磺酸钠/异辛烷/甲苯/水反胶束中上述模型反应的稳态动力学并与水介质做了比较。

The optimal parameters for catalytic reaction of LiP or MnP on theelectrode in electrochemical enzyme sensor are obtained,which are pH of4.2,H_2O_2 concentration reaching 0.1875 mM,0.25 mM hydroquinone and 6mM veratryl alcohol.In the optimal reaction system,LiP and MnP aredetermined exactly by the sensor.

实验确定了电化学酶传感器裸玻碳电极对LiP、MnP体系的催化反应的响应最为灵敏且电流变化较大的最适pH值(pH4.2)、H_2O_2(0.1875 mM)、对苯二酚(0.25 mM)、藜芦醇(6 mM)含量等参数，在该反应条件下传感器能准确测定LiP、MnP。

Nitraria tangutorum, Zygophyllum xanthoxylum, Reaumuria soongorica, Ammopiptanthus mongolicus, Atraphaxis bracteata, Haloxylon ammodendron, Ceratoides latens, which are widely distributed in the Alashan arid desert area were selected for study.
