摘　　要：利用土壤真菌和植物的结合体菌根真菌修复土壤,尤其是修复有机污染的根际土壤.正作为一个新的研究方向开始受到广泛关注。菌根真菌作为土壤真菌的一种,与放线菌和细菌等微生物相比,对土壤中有机污染具有更大的忍耐能力.并且能将许多持久性有机污染物(POPs)做为碳源来获取能量。文章通过总结近20年菌根真菌与土壤有机污染物关系的研究,列出了43种能分解POPs的菌根真菌,并探讨了菌根真菌通过直接分解和共代谢的方式降解土壤有机污染物的可能性,为进一步研究菌根真菌生物降解土壤中持久性有机污染物,利用菌根植物生物修复有机污染土壤提供信息。Owing to its persistence in the environment and potential harmfulness to human health, more and more attention has been paid to the persistence organic pollutants (POPs) in soil, and using rhizosphere microorganisms to remedy soil organic pollution is becoming a kind of new research field. Compared with other microbes such as bacteria and actinomycete, mycorrhizal fungi have higher tolerance to POPs in soil. Having reviewed the last 20 years of researches on the relationship between mycorrhizal fungi/plant and organic pollution, we listed 43 strains of mycorrhizal fungi which have the ability to degrade POPs in their growth environment. Furthermore, mechanism of mycorrhizal fungi to degrade POPs with direct-degradation and co-metabolism has been discussed.
