【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。
[Abstract]:The biodegradation of organic pollutants by microbial co-metabolism has attracted wide attention due to its high efficiency and uniqueness. However, the present laboratory studies mainly focus on aerobic co-metabolism and anaerobic co-metabolism. There are few studies on the co-metabolism of facultative microorganisms and its mechanism. In this paper, the co-metabolism of aerobic, anaerobic and facultative microorganisms in the treatment of refractory pollutants in printing and dyeing wastewater was introduced, and the research progress of facultative microorganism co-metabolism in treatment of printing and dyeing wastewater at home and abroad was emphatically reviewed. The results of comprehensive analysis show that facultative microorganisms can effectively degrade many kinds of dyes, auxiliaries and so on under the condition of facultative oxygen, so long as the suitable co-metabolic matrix is provided, and the facultative microorganism can effectively degrade many kinds of dyes and auxiliaries. At the same time, facultative microbial co-metabolism has the advantages of not requiring a large amount of energy power and producing a large amount of odorous substances. It is concluded that the study on the mechanism of facultative microorganism co-metabolism can be strengthened in the future to further improve the efficiency of facultative microorganism co-metabolism treatment of pollutants and promote its further development. Finally, the research direction of the mechanism of facultative microorganism co-metabolism is prospected, in order to screen the dominant functional bacteria in the microflora, to carry on the protein differential expression, the proteomics research. In order to promote the treatment effect of functional flora, the proportion of microbial community structure in co-metabolic treatment of printing and dyeing wastewater was optimized, which provided more reference and reference for solving the problem of biological treatment of printing and dyeing wastewater in the future.
