This paper reviews pathways of aerobic and anaerobic microbiological degradation of PCP. It can be concluded that reductively dechlorination prior to ring cleavage plays a key role in mineralization of PCP.

文章通过综述好氧与氧微生物降解五氯酚的降解菌和降解途径,认为五氯酚首先通过脱氯转化为低氯代化合物后再开环,因此脱氯就成为五氯酚降解的关键步骤。

Dissimilatory Fe oxide reduction under anaerobic condition is a process which is an anaerobic respiration with Fe as the terminal electron acceptor. This anaerobic respiration showed important environmental significances. Dissimilatory Fe reducers can use diverse electron acceptors including many toxic heavy metals and metalloids such as Mn、Cr、Co insides Fe. So these toxic metals were detoxified or were immobilized reductively.

这种氧呼吸作用具有重要的环境学和地学意义,Fe还原微生物可利用除Fe以外的许多其它电子受体包括许多有毒重金属和类金属,如Mn、Cr、Co等,从而对这些有毒重金属起到还原解毒或还原固定的作用;还原过程还可促进一些有机污染物的降解; Fe氧化物的还原偶联着Si、P等元素的变化,对提高这些营养元素的有效性发挥着重要作用。
