“…2), and closely matched those retrieved from sediments and WWTP systems. Interestingly, 34 % of sequences in cluster B showed substantial overlap with those from active sludge (Sliekers et al 2004;Figuerola and Erijman 2010;Yu et al 2011;Zhang et al 2011;Gao et al 2013Gao et al , 2014Langone et al 2014), and OTU27 (mainly including sequences from W4) was 99 % identical to Nitrosomonas europaea ATCC 19178. This revealed that bacterial amoA sequences from summer and winter were associated with genera Nitrosospira and Nitrosomonas, respectively, as Nitrosospira and Nitrosomonas are the two main AOB groups in various soil and freshwater environments, especially in aquatic environments affected heavily by anthropogenic inputs Wankel et al 2011;Luo et al 2014).…”

Ammonia oxidation, driven by ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB), plays an important role in the global nitrogen cycle. However, the population and distribution of ammonia-oxidizing microorganisms in the sediments of urban rivers with intensive anthropogenic nitrogen inputs is still unclear. In this study, we compared the diversity and abundance of AOA and AOB in Beiyun River sediments from summer to winter. AOB dominated numerically over AOA and the abundance of both the amoA genes were much higher in winter than in summer, while AOA communities were more phylogenetically diverse than AOB in this study area. Phylogenetic analysis revealed that Nitrosospira sp. was the dominant AOB in summer, with Nitrosomonas sp. dominant in winter, while no specific genus was found for AOA in present study. The main pollutants and microbial communities in the sediments deriving from Yangwa Watergate were different from other sites. Clone libraries showed that a considerable percentage of amoA sequences matched closely with those from wastewater treatment plant (WWTP) systems. The seasonal change in nitrate content was significantly and positively related to the seasonal variation in amoA abundance (P < 0.05). Total nitrogen, total organic carbon, ammonium, and pH were the main environmental factors accounting for the difference in community composition of ammonia-oxidizing microorganisms in the sediments of Beiyun River. These findings suggest that effluent inputs, water gate operation, and seasonal changes might be key factors determining the abundance and distribution of AOB and AOA in the sediments of urban rivers.

“…qPCR is accepted as a rapid technique which gives accurate information in wastewater treatment systems investigating microbial community change and nitrification performance. Applications include determination of nitrifying bacteria abundance and its behaviour in treatment plants treating domestic sewage and different types of industrial wastewaters (Figuerola et al, 2010;Geets et al, 2007).…”

“…Since profiles were very variable within and between reactors, data was not shown and further analyzed. However, in all bioreactors (regardless of pharmaceutical concentration) we have found one dominant T-RF of 219 bp, which represents Nitrosomonas europaea/eutropha lineage [25] and was very often found as the dominant AOB in WWT [26,27].…”
