摘　　要：介绍了共代谢作用的内涵、分类以及能够进行共代谢作用的部分微生物,较为详细地阐述了共代谢作用过程的机制,包括关键酶的作用,竞争性抑制作用、毒性效应以及微生物的自我解毒和恢复机能,能量调节和还原力供应等方面。综合分析了共代谢作用过程的动力学特征及相关模型。对利用微生物共代谢作用进行难生物降解污染物去除的关键因素作了深入的分析。The connotation, classification of co-m etabolism and a portion of microbes capable of co-metabolically degrading the biorefractory pollutants were described. The function mechanism of co-metabolism was expatiated, including the action of key enzyme, competitive inhibition, toxicity effect, detoxification, recovery of microbes, energy regulation and reductant supply. Kinetic characteristics and related models of co-metabolism process were analyzed in detail. Meanwhile, transformation or degradati important in the practice application were also on of pollutants by co-metabolism style and the influence factors being analyzed in depth.
