Abstract: The advances in the researches on impact of easily degradable organic matter on refracfory organic pollutants biodegradation around the world are reviewed in terms of growth metabolism，cometabolism and changing the bioavailability of the refractory organic pollutants through reaction with easily degradable organic matter. In light of the knowledge of microbiology and bioavailability of refractory organic pollutants，research topics to be done are proposed.

摘要： 基于生长代谢、共代谢原理及易降解有机物与难降解有机物存在形式与形态的影响而改变其生物可利用性等角度，综述了易降解有机物对难降解污染物生物降解影响的研究进展，并基于微生物生态学及污染物生物可利用性的知识，探讨了有待深入研究的问题。
