“…Overall, our results are in good agreement with a previous study, wherein the microbial communities of sludge and membrane biofilm of 10 full scale MBRs were compared (Jo et al, 2016). Although, there are differences in the relative abundance of bacterial groups in the sludge and the biofilm, the microbial community is largely similar in both samples.…”

“…Also, they have the ability to spread rapidly to form monolayers of cells on the surfaces, which can develop into multicellular mushroom shaped structures (Tsang et al, 2006). Furthermore, Flavobacteriia that contribute in flocs and biofilm formation were double in the biofilm community as compared to the sludge (Jo et al, 2016) (E-supplementary data of this work can be found in online version of the paper). Proteobacteria, Bacteroidetes, Actinobacteria, Planctomycetes and Chloroflexi were found to be the dominant bacterial phyla in both sludge and membrane biofilm communities (Jo et al, 2016;Lim et al, 2012;Ziegler et al, 2016).…”

“…The species in this genus could also be isolated from diseased fish, domestic drain conduits, and potable dental lines [26]. Recently, Jo et al [27] reported that it could be abundantly present in full-scale membrane bioreactors. These results suggested that this genus probably prefers biofilm environments and may contribute to biofilmformation.…”

The oxidation ditch (OD) is one of the most widely used processes for treating municipal wastewater. However, the microbial communities in the OD systems have not been well characterized, and little information about the shift of bacterial community during the startup process of the OD systems is available. In this study, we investigated the bacterial community changes during the startup period (over 100 days) of a full-scale OD. The results showed that the bacterial community dramatically changed during the startup period. Similar to the activated sludge samples in other studies, Proteobacteria (accounting for 26.3%-48.4%) was the most dominant bacterial phylum in the OD system, but its relative abundance declined nearly 40% during the startup process. It was also found that Planctomycetes proliferated greatly (from 4.79% to 13.5%) and finally replaced Bacteroidetes as the second abundant phylum in the OD system. Specifically, some bacteria affiliated with genus exhibited remarkable decreasing trends, whereas bacterial species belonging to the OD1 candidate division and Saprospiraceae family were found to increase during the startup process. Despite of the bacterial community shift, the organic matter, nitrogen, and phosphorus in the effluent were always in low concentrations, suggesting the functional redundancy of the bacterial community. Moreover, by comparing with the bacterial community in other municipal wastewater treatment bioreactors, some potentially novel bacterial species were found to be present in the OD system. Collectively, this study improved our understandings of the bacterial community structure and microbial ecology during the startup of a full-scale wastewater treatment bioreactor.

“…Furthermore, very little is known about differences (if any) in viral composition between common wastewater treatment process variations, particularly between systems that use suspended versus attached bacterial growth for secondary treatment. Differences could result from the fact that WWTPs using biofilm and suspended growth forms of secondary treatment can contain microbial communities that collectively achieve similar outcomes for nutrient removal, but relative abundances of specific bacterial taxa tend to vary across different types of WWTPs (Wagner and Loy, 2002;Jo et al, 2016). Some viruses correspond to specific host taxa, thus the bacterial community composition may influence viral community structure, and simultaneously, viruses can influence bacterial communities by causing bacterial mortality (Fuhrman and Schwalbach, 2003).…”

Summary Wastewater treatment plants (WWTPs) contain high density and diversity of viruses which can significantly impact microbial communities in aquatic systems. While previous studies have investigated viruses in WWTP samples that have been specifically concentrated for viruses and filtered to exclude bacteria, little is known about viral communities associated with bacterial communities throughout wastewater treatment systems. Additionally, differences in viral composition between attached and suspended growth wastewater treatment bioprocesses are not well characterized. Here, shotgun metagenomics was used to analyse wastewater and biomass from transects through two full‐scale WWTPs for viral composition and associations with bacterial hosts. One WWTP used a suspended growth activated sludge bioreactor and the other used a biofilm reactor (trickling filter). Myoviridae, Podoviridae and Siphoviridae were the dominant viral families throughout both WWTPs, which are all from the order Caudovirales. Beta diversity analysis of viral sequences showed that samples clustered significantly both by plant and by specific sampling location. For each WWTP, the overall bacterial community structure was significantly different than community structure of bacterial taxa associated with viral sequences. These findings highlight viral community composition in transects through different WWTPs and provide context for dsDNA viral sequences in bacterial communities from these systems.
