Rehabilitaion of groundwater contaminated by chloroethene using membrane immobilized peroxidase

为了加速地下氯乙烯污染的生物修复，对酶的利用特别是过氧化物酶及其相关酶进行了研究。四氯乙烯、三氯乙烯、顺-1，2-二氯乙烯和氯乙烯作为氯化乙烯化合物。商品辣根过氧化物酶在各自的最佳条件下用于氯化乙烯的分解，但没有发现这些化合物有明显的降解作用。木质素过氧化物酶和锰过氧化物酶对氯化乙烯也没有影响。被测的漆酶和过氧化氢酶不与这些化合物反应。

In order to accelerate bioremediation of chlorinated ethene contaminated subsurface, enzyme utilization especially peroxidases and relatives was studied. Tetrachloroethylene, trichloroethylene, cis-1,2-dichloroethylen, and vinyl chloride were used as chlorinated ethene compounds. Commercially available horseradish peroxidases were used for decomposition of chlorinated ethene under respective optimal conditions but obvious degradation of these compounds were not recognized. Lignin peroxidase and manganese peroxidase also represented no effect on chlorinated ethene. Laccase and catalase tested did not react with these compounds.
