“…AOA and AOB diversity and abundance in the sediments of Beiyun River Diversity estimates based on clone libraries of amoA genes in this study were within the same range of that in the sediments of estuaries (Wankel et al 2011;Zheng et al 2013;Chen et al 2014) and freshwater lakes (Liu et al 2015), while these indices were generally higher than that reported in the sediments of eutrophic lake (Zeng et al 2012;Zhao et al 2013Zhao et al , 2014. Archaeal amoA sequences from the eight samples showed higher Shannon diversity than bacterial amoA, which was in agreement with the results in previous studies Zheng et al 2013).…”

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.

“…The important roles of sediment microbes in energy and matter transformation in aquatic environments have been reported previously (Boyle-Yarwood et al 2008;Glissman et al 2004;Schmalenberger et al 2008;Tamaki et al 2005). Some studies about the sediment microbes have been performed on the functional microorganisms, such as the methanogens (Antony et al 2012), the Miscellaneous Crenarchaeotic Group , and the ammoniaoxidizing bacteria (Zhao et al 2013). Others dealt with the diversity shift of microorganisms against the changes of environment factors (Blöthe et al 2008;Hoostal and Bouzat 2008;Wang et al 2011), and also the spatial and temporal variations of sediment bacteria (Bai et al 2012 Nam et al 2008;Qu et al 2008;Szabó et al 2011).…”

To investigate the temporal variation of the sediment prokaryote communities and their relation with the rapid increase of algae population in Taihu, a shallow eutrophic freshwater Lake, water and surface sediments were sampled from seven sites in different stages of algal bloom. The physicochemical characterization revealed positive correlations among the nutrient (N, P) parameters in the water and sediments, as well as TN/TP ratio 30.79 in average in water and 0.13 in sediments, demonstrating that P content was the limit factor for bloom in Taihu and sediment was an important nutrient resource for the water body. T-RFLP analysis of 16S rRNA genes revealed a diversity decrease of sediment prokaryotic communities along the bloom. The bacterial communities in sediments were more sensitive and shaped by the temporal changes, while archaea were more sensitive to the trophic level. The pyrosequencing data showed clear spatial and temporal changes in diversity of sediment bacteria. Betaproteobacteria was the most abundant group in all the samples, following by Delta-, Gama- and Alpha-proteobacteria, Acidobacteria, Chlorobi, Chloroflexi etc. At the genus level, Thiobacillus and Sulfuricurvum were the most dominant groups in the sediments, and the increase of Thiobacillus abundance in February might be used as bioindicator for the subsequent bloom. In addition, NO3 (-)-N was evidenced to be the main factor to regulate the bacterial community structure in the sediments. These results offered some novel and important data for the evaluation and predict the algal bloom in Taihu and can be reference for other shallow fresh water lakes.

“…The distribution of sediment ammonia-oxidizing archaeal and bacterial populations has been investigated in a variety of freshwater ecosystems, such as river (Reis et al 2015;Sonthiphand et al 2013;Sun et al 2013;Xie et al 2014), reservoir , lake (Bollmann et al 2014;Hou et al 2013;Liu et al 2015;Mukherjee et al 2016;Zhao et al 2013Zhao et al , 2014, wetland (Liu et al 2014a;Wang et al 2013;Yang et al 2014), and pond (Lu et al 2015), yet the relative importance of AOA and AOB to nitrification process in freshwater sediments remains under debate. Several previous studies indicated that AOA amoA gene abundance was usually greater than AOB in lake sediments (Herrmann et al 2009;Hou et al 2013;Zhao et al 2014), while the numerical dominance of AOB over AOA amoA gene abundance was observed in sediments of many freshwater lakes on the Yunnan Plateau (Liu et al 2015).…”

Both ammonia-oxidizing archaea (AOA) and bacteria (AOB) can play important roles in the microbial oxidation of ammonia nitrogen in freshwater lake, but information on spatiotemporal variation in water column and sediment community structure is still limited. Additionally, the drivers of the differences between sediment and water assemblages are still unclear. The present study investigated the variation of AOA and AOB communities in both water columns and sediments of eutrophic freshwater Dianchi Lake. The abundance, diversity, and structure of both planktonic and sediment ammonia-oxidizing microorganisms in Dianchi Lake showed the evident changes with sampling site and time. In both water columns and sediments, AOB amoA gene generally outnumbered AOA, and the AOB/AOA ratio was much higher in summer than in autumn. The total AOA amoA abundance was relatively great in autumn, while sediment AOB was relatively abundant in summer. Sediment AOA amoA abundance was likely correlated with ammonia nitrogen (rs = 0.963). The AOB/AOA ratio in lake sediment was positively correlated with total phosphorus (rs = 0.835), while pH, dissolved organic carbon, and ammonia nitrogen might be the key driving forces for the AOB/AOA ratio in lake water. Sediment AOA and AOB diversity was correlated with nitrate nitrogen (rs = -0.786) and total organic carbon (rs = 0.769), respectively, while planktonic AOB diversity was correlated with ammonia nitrogen (rs = 0.854). Surface water and sediment in the same location had a distinctively different microbial community structure. In addition, sediment AOB community structure was influenced by total phosphorus, while total phosphorus might be a key determinant of planktonic AOB community structure.
