Abstract:

考察了以污水处理厂的好氧污泥作为接种污泥,以S0作为电子供体培养驯化硫自养高氯酸盐还原菌的过程,并利用PCR-DGGE技术对不同阶段的污泥样品进行群落分析。结果表明,接种污泥在经过短暂的适应期后能具有较高的还原ClO4-的性能,随着驯化时间的延长,降解速率显著提高。培养驯化过程中微生物种群结构发生了演替变化,菌种Dechloromonassp.CL、Quadrisphaeragranulorum、Comamonadaceaebacterium32-4、Acidovoraxcaeni、filamentousbacteriumPlant1Iso8、CandidatusNitrospiradefluvii存在整个驯化培养阶段。随着培养驯化时间的延长,菌种BacteroidetesbacteriumS22-33、Herbaspirillumhuttiense逐渐消失,出现新菌种Methyloversatilisuniversalis、betaproteobacteriumHTCC379、betaproteobacteriumCDB21和Clostridiumbifermentans,并逐渐成为优势菌种。
