【摘要】：微生物菌群一直是活性污泥研究過程中的關鍵問題,近年來通過分子生物學等研究手段已經(jīng)發(fā)現(xiàn)動膠菌是活性污泥微生物菌群中的優(yōu)勢細菌.本文以活性污泥微生物菌群為出發(fā)點,重點梳理了動膠菌屬分類學研究歷史和現(xiàn)狀,并建議在前期命名過程中出現(xiàn)的垂(懸)絲狀動膠菌和生枝動膠菌ATCC 19623株及ATCC 25935株不應再作為動膠菌屬細菌對待.同時介紹了動膠菌屬細菌的基本特性及其在活性污泥法處理廢水中降解有機物、除磷脫氮和吸附重金屬離子等方面的應用,以及動膠菌胞外多聚物的組成和動膠菌優(yōu)良菌株的選育.我們及合作者最近分析了兩個喜樹脂動膠菌的基因組并鑒定出參與菌膠團形成的一個大型基因簇,也實現(xiàn)了基因定點敲除等遺傳操作.今后研究應重點關注動膠菌分子遺傳學、功能基因組學及胞外多聚物生物合成和菌膠團形成機理、化學結(jié)構(gòu)和性質(zhì).
[Abstract]:Microbial flora is the key problem in the research process of activated sludge. In recent years, it has been found that GerB is the dominant bacteria in the microbial flora of activated sludge by means of molecular biology. This paper focuses on the history and present status of the taxonomy of the genus gerbie, and suggests that the microbial flora of activated sludge is the starting point. The vertical (suspended) filamentous germs, 19623 strains of ATCC and 25935 strains of ATCC should not be treated as germs, and the basic characteristics of the bacteria of the genus geriti and the degradation of organic compounds in the wastewater treatment by activated sludge process, phosphorus removal and adsorption of heavy metal ions were also introduced. As well as the composition of the extracellular polymeric substances and the breeding of fine strains of the bacteria, we and the collaborators have recently analyzed the genome of two strains of the gum resin and identified a large gene cluster involved in the formation of bacterial micelles, and also the genetic manipulation of fixed gene knockout. The future research should focus on the molecular genetics of the bacteria. Studies, functional genomics, extracellular polymeric biosynthesis, bacterial micelles formation mechanism, chemical structure and properties.
