持久性有机污染物（POPs）具有高毒性和低可降解性的特征，通过先进的生物修复技术来治理POPs污染正受到公众普遍的关注．而提高生物可利用性则可以突破原位生物修复的瓶颈；宏基因组技术可以获得大量的降解基因资源；利用生物工程手段，可以大幅度提高降解菌的能力．这3个方面是目前POPs生物修复领域的研究热点．

英文摘要：

Due to the potential toxicity and poor degradation of POPs, advanced bioremediation, a novel effectively removing technique to POPs in various contaminated environmental media including water, sediments and soils, was more and more concerned by public.. With recent advances in the field of biomolecular engineering, the capability of microorganisms to hioremediate POPs could be greatly improved. Low bioavailability, the bottleneck of in situ bioremediation, would be broken through by the study of biosurfactant and chemtaxis; Metagenome could provide us with a large amount of useful genes involved in POPs degradation which traditional culture technique couldnt do. Recently, elevation of POPs bioavailabiliity, exploration of degradation gene from non-cultured microorganism, and construction of Genomic Engineering microorganism（ GEM ）, are three hotspots in research of POPs bioremediation.
