IntroductionThe community structure of groundwater microorganisms has a significant impact on groundwater quality. However, the relationships between the microbial communities and environmental variables in groundwater of different recharge and disturbance types are not fully understood.MethodsIn this study, measurements of groundwater physicochemical parameters and 16S rDNA high-throughput sequencing technology were used to assess the interactions between hydrogeochemical conditions and microbial diversity in Longkou coastal aquifer (LK), Cele arid zone aquifer (CL), and Wuhan riverside hyporheic zone aquifer (WH). Redundancy analysis indicated that the primary chemical parameters affecting the microbial community composition were NO3–, Cl–, and HCO3–.ResultsThe species and quantity of microorganisms in the river–groundwater interaction area were considerably higher than those in areas with high salinity [Shannon: WH (6.28) > LK (4.11) > CL (3.96); Chao1: WH (4,868) > CL (1510) > LK (1,222)]. Molecular ecological network analysis demonstrated that the change in microbial interactions caused by evaporation was less than that caused by seawater invasion under high-salinity conditions [(nodes, links): LK (71,192) > CL (51,198)], whereas the scale and nodes of the microbial network were greatly expanded under low-salinity conditions [(nodes, links): WH (279,694)]. Microbial community analysis revealed that distinct differences existed in the classification levels of the different dominant microorganism species in the three aquifers.DiscussionEnvironmental physical and chemical conditions selected the dominant species according to microbial functions. Gallionellaceae, which is associated with iron oxidation, dominated in the arid zones, while Rhodocyclaceae, which is related to denitrification, led in the coastal zones, and Desulfurivibrio, which is related to sulfur conversion, prevailed in the hyporheic zones. Therefore, dominant local bacterial communities can be used as indicators of local environmental conditions.

“…Water temperature ( T ), pH, electric conductivity, oxidation–reduction potential, and total dissolved solids (TDSs) were measured in the field. The laboratory analysis was carried out within 24 h, following the standard methods suggested by the Ministry of Ecology and Environment of China, which were presented in our earlier study . The tested items included total organic carbon (TOC), ammonia nitrogen (NH 3 -N), nitrite (NO 2 – -N), nitrate (NO 3 – -N), total phosphorus (TP), and Fe, Mn, K, Mg, Ca, and Si.…”

Bacteria and microeukaryotes inhabiting urban freshwater are susceptible to environmental disturbance, particularly effluents from wastewater treatment plants (WWTPs). However, how riverine microbial community succession responds to WWTP effluent and its assembly processes remains poorly addressed. Herein, surface water samples were collected from an urban river to explore the community dynamics and assembly processes under the impact of the WWTP effluent. Physicochemical property variation (e.g., total phosphorus and nitrate concentration) caused by wastewater was more strongly correlated with the microbial community than with geographic distance. Importantly, deterministic processes increase from 34.8 to 93.3% for bacterial community assembly from upstream to downstream. Betaproteobacteria, Bacillariophyta, and Chlorophyceae exhibited essential roles in mediating the community composition against WWTP effluent discharge. In addition, bacteria tend to have a stronger interaction in wet or normal periods, while microeukaryotes may have more stable networks in dry periods. Seasonal variation caused a significant discrepancy (ANOVA P = 0.001) in community composition for both bacteria and microeukaryotes. Our work provides systematic information on how treated wastewater contributes to microbial community succession and identifies the potential keystone taxa during the microbial response in wastewater, which may lead to improved management of wastewater discharge and river health.

“…Due to the thick ice on the surface of the river, we were able to collect only 7 of 10 samples during the ice-sealed period. Figure 1 illustrates the sampling locations [33,34], and the longitude and latitude information for each point is provided in Table S1. We positioned ten sampling sites throughout a 29.5 km section of the Yitong River in the city of Changchun (43°71′ N to 43°97′ N, 125°34′ E to 125°36′ E).…”

Although reclaimed water (RW) has become a promising alternative source for alleviating water shortage in arid and semiarid regions, the ecological risks it poses to the receiving water bodies remain largely unknown. Dissolved organic matter (DOM) is crucial for affecting the quality of RW and strongly influences bacterial communities (BCs) in aquatic ecosystems. In this study, we aimed to unravel the role of DOM signatures on the spatiotemporal composition of microbial communities (MCs) in a seasonally ice-sealed urban river that had been chronically replenished by RW. We found that discharging RW resulted in elevated DOM levels in the receiving river. Notably, an increase of 10% in protein-like substances was revealed. The differences between compositional characteristics of DOM and the abundance of riverine BCs between freezing and non-freezing periods were revealed. In the freezing season, humic-like components, aromaticity, and hydrophobicity of DOM were more significant, and bacterial taxa such as Bacteriodetes and Flavobacterium were increased, while Proteobacteria was decreased. Similarly, co-occurrence network analysis revealed an enhanced interplay between DOM and BCs at the same time. However, Klebsiella pneumoniae markedly decreased during the ice-sealed period. These results suggest that variations in DOM characteristics have remarkable impacts on the dynamics of aquatic BCs, which points to the need for a DOM−oriented RW quality monitoring strategy.
