英文摘要：

The pathways for biodegradation of persistent organic pollutants （POPs） are summarized and the potential capability of ectomycorrhizal fungi （ECMF） to degrade POPs is described in this review. POPs, such as PCBs and DDT, can be metabolized through the process of dechlorination or ring cleavage, according to the microorganisms and environmental conditions. Many researches show that a lot of ectomycorrhizal fungi can degrade several POPs. The likely mechanisms by which ECMF can biodegrade POPs are suggested, and their advantages and constraints are proposed in this paper. Fig 2, Tab 2, Ref 30 .
