摘要:

通过构建克隆文库,对反应器类型和污泥形态对厌氧氨氧化(anammox)细菌的群落结构的影响进行探索. 研究发现,反应器类型对anammox细菌群落结构影响不大,但其种泥来源对功能细菌的群落结构有一定影响. 污泥形态对anammox细菌群落结构有着重要影响,絮体污泥中的anammox细菌以Candidatus Kuenenia为主;聚集态污泥中的anammox细菌则以Candidatus Brocadia为优势菌;在同时存在絮体污泥和生物膜的复合式反应器中,不同污泥形态中anammox细菌在接触时会发生迁移,但其优势菌种不发生变化.

关键词: 厌氧氨氧化细菌, 颗粒污泥, 絮体污泥, 生物膜污泥, PCR-Clone

Abstract:

In this study, all the dominant anammox bacteria were distributed over two genera, Candidatus Brocadia and Kuenenia, in four anammox reactors. It was shown that sludge morphology played an important role in the bacterial community structure of anammox bacteria. More than 36 percents of anammox bacteria in granular sludge and biofilm belonged to Candidatus Brocadia, while in flocculent sludge the domninant anammmox bacteria was Candidatus Kuenenia. Anammox bacteria in different sludge morphologies would migrate in the same reactor, but the dominant species remained.

Key words: anammox bacteria, granular, flocculent, biofilm, PCR-clone
