Abstract
A cell extract of a polychlorophenol-degrading bacterium, Rhodococcus sp. strain CP-2, isolated from chlorophenol-contaminated soil, was shown to dechlorinate tetrachlorohydroquinone, the first intermediate in pentachlorophenol and 2,3,5,6-tetrachlorophenol degradation. Degradation of tetrachlorohydroquinone was catalyzed by a soluble enzyme(s). The reaction sequence for complete dechlorination involved hydroxylation and three reductive dechlorinations, producing 1,2,4-trihydroxybenzene. All chlorines were thus removed from the polychlorinated compound before ring cleavage.
摘要
从含氯酚污染土壤中分离到的多氯酚降解菌 Rhodococcus sp. CP-2 的细胞提取物被证明能够脱氯四氯氢醌，这是五氯酚和 2,3,5,6-四氯酚降解的第一个中间产物。四氯氢醌的降解由可溶性酶（s）催化。完全脱氯的反应序列包括羟化和三个还原脱氯，生成 1,2,4-三羟基苯。因此，在环断裂之前，多氯化合物中的所有氯都被去除了。
