The impact of water level change on the abundance and diversity of ammonia oxidizing bacteria(AOB) and ammonia oxidizing archaea(AOA) in water-fluctuating zone
South-to-North Water Diversion directly lead to the rise of water level of the Miyun reservoir,which would change the abundance and the diversity of ammonia oxidizing microorganism,and then affect the nitrogen cycling in water-fluctuating zone.The impact of water level change on the abundance and diversity of ammonia oxidizing bacteria(AOB) and ammonia oxidizing archaea(AOA) in water-fluctuating zone were analyzed in this study.Quantitative Real-time PCR results show that the copy numbers of AOA and AOB var...

1引言(Introduction)氨氧化过程是硝化作用的第一步反应并且是限速步骤,在整个氮循环中发挥着重要的作用(Troelstra et al.,1990;Kowalchuk et al.,2001).2005年前,学者们认为氨氧化细菌(Ammonia-oxidizingbacteria,AOB)是唯一驱动氨氧化过程的微生物(Head et al.,1993).但从氨
