摘　　要：利用微生物共代谢降解有机污染物因其高效性和独特性而受到广泛地关注,但是目前实验室研究主要以好氧共代谢和厌氧共代谢研究为主,对于兼性微生物共代谢作用及其机制研究较少。本文综合介绍了好氧微生物、厌氧微生物以及兼性微生物共代谢处理印染废水中难降解污染物的情况,着重回顾了国内外兼性微生物共代谢处理印染废水的研究进展。综合分析文献结果表明,在兼氧条件下,只要提供适合的共代谢基质,兼性微生物可以对多种不同类型的染料、助剂等进行有效地降解,同时兼性微生物共代谢具有不需要大量能源动力,不产生大量臭气物质等优点。分析认为今后可加强兼性微生物共代谢相关机理研究,进一步提高兼性微生物共代谢处理污染物的效率,促使其深入发展。最后展望了兼性微生物共代谢技术机理的研究方向,以期筛选出菌群中优势功能菌种,进行蛋白质差异表达、蛋白质组学方面的研究,并不断优化印染废水污染物共代谢处理微生物群落结构比例来促进功能菌群的处理效果,为今后解决印染废水生物治理问题提供更多借鉴和参考。The use of microbial co-metabolism degradation of organic pollutants in wastewater has drawn more and more attention because of its high efficiency and uniqueness.At present,majority of laboratory researches were on aerobic co-metabolism and anaerobic co-metabolism.There were few studies on the co-metabolism of facultative microorganisms.In this paper,aerobic microorganisms,anaerobic microorganisms and facultative microorganisms co-metabolize the refractory pollutants in printing and dyeing wastewater were introduced.The results showed that at the aerobic,anaerobic,and facultative conditions,different target pollutants has their own most appropriate co-substrates.The domestic and overseas research progresses of facultative metabolic treatment of printing and dyeing wastewater were the main focus for this paper.Under the facultative condition,facultative microorganisms were able to effectively degrade various different types of dyes,additives etc.,as long as providing suitable co-substrates.At the same time,facultative microbial co-metabolism had the advantages of not requiring of a lot of energy and not producing of large amount of odorous substances.The results suggested that further studies on the mechanism are needed in the future,and the efficiency of microbial co-metabolism can be further improved.Finally,the research on the mechanism of facultative microbial co-metabolism needs to be conducted to screen out the dominant bacteria in functional strains,to carry on the differentially expressed proteins and proteomics research.Constantly optimizing the proportion of microbial community structure in dyeing wastewater will promote the treatment effect of functional flora and provide more insight for the solution of printing and dyeing wastewater biotreatment in future.
