In this study, we used the static chamber method, combined with 16S rRNA-based, metagenomic sequencing and binning techniques, to investigate the emission patterns of greenhouse gases (GHGs), with a particular focus on CH₄, in mangroves subjected to different levels of effluents. The results showed that the effluent input decreased the mineral protection of sediment carbon (C) pools and increased C loss by more than double. In particular, high effluent input increased CH₄ emissions by 243.3%. Random forest analysis revealed that changes in methanogens were an important factor in explaining the variation of CH₄ emissions. Amplicon data showed that the proportion of methylotrophic methanogens increased after effluent input, and metagenomic binning further attributed this change to the adaptability of methylotrophic methanogens to the substances transporting by the effluent. The enhanced hypoxia in sediments resulting from effluent input promoted the transition of methanotrophic communities from aerobic to anaerobic types, and made anaerobic oxidation of CH₄ more reliant on sulfur reduction rather than nitrate reduction. The PLS model further revealed that the nutrients brought by effluent input stimulated an increase in DOC content which induced an imbalance between CH₄ production and oxidation in sediments by facilitating methanogens but inhibiting methanotrophs, ultimately resulting in an increase in CH₄ fluxes. These findings underscore the significance of mangroves receiving effluent input as critical consequent reactors, highlighting the necessity to consider effects of high nutrient enrichment by aquaculture effluent input on GHG emissions and blue C potential in mangroves.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"27 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143695704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a sustainable strategy involving the transformation of diatomite into a water purification catalyst consisting of nano-size pore enrichment and silico-oxygen bonding (Si/C@BD) was proposed. Results indicated that the pollutants with electron-donating groups can be quickly degraded by the Si/C@BD via amplified electron transfer process (ETP) under very low peroxymonosulfate (PMS) usage. Such “low-oxidant-consumption” Fenton-like chemistry can be also applied to other catalytic systems derived from a series of silicon-based materials. In addition, a pilot-scale device (54 L) based on ETP pathway was constructed, which provided a universal strategy to prevent direct contact of treated wastewater with oxidation additives, thereby solving the bottleneck of secondary pollution caused by sulfate dissolution associated with PMS oxidation systems. In addition, the Si/C@BD/PMS system exhibited the superior environmental significance and feasibility based on the quantitative analysis via the life cycle assessment (LCA).

The spatial and temporal diversity patterns and mechanisms governing these microbial communities are not yet well understood. Our study revealed that microbial richness decreased rapidly during the initial freezing period. However, it began to increase during the deep freezing period due to the role of cold-resistant microorganisms. Meanwhile, the diversity of microorganisms showed a trend that was in line with the lake water- groundwater changes in temperature. <em>Achromobacter</em> and <em>Crenothrix</em> have been designated as biomarkers for the initial freezing period and deep freezing period, respectively. In these phases, factors such as dispersal limitation (26.8%-47.6%) and drift (15.1%-45.2%), along with other random factors, are the primary drivers of bacterial community assembly. Physical properties (pH, T, DO, EC, Eh) have been identified as the predominant factors (r=0.75, p&lt;0.01) affecting the progression of community succession in hyporheic systems throughout the freeze-thaw cycles. Conversely, nutrient properties (r=0.36, p&lt;0.01) and the presence of heavy metals (r=0.18, p&lt;0.01) play lesser roles, influencing community composition according to partial least squares path modeling.

However, the electron transfer mechanism of the core redox reaction and its evolutionary origins are still not thoroughly identified. In this study, a preliminary analysis was conducted for such interaction based on the 64 anammox bacterial genomes representing 12 genera available currently. The results suggested that enzymes involved in anammox reaction share the similar catalytic and electron transfer modes in different lineages, while the electron-carrying proteins shuttled between membrane and soluble enzymes are very different. A comparatively simple electronic shuttle protein system was encoded in the early-branching groundwater lineages Candidatus (Ca.) Avalokitesvara and <em>Ca</em>. Tripitaka, which was replaced by a sophisticated electron carrier scheme in the late-branching marine and terrestrial groups within family <em>Ca</em>. Brocadiaceae. Remarkably, the increasing availability of nitrite after Great Oxidation Event (GOE) potentially drove the adaptive evolution of the core redox systems by successively recruiting the nitrite reductase (NIR) for nitrite balance, a stable complex of two small cytochrome <em>c</em> proteins (NaxL and NaxS homologues) for electron transfer to HZS, as well as optimizing the structure of nitrite oxidoreductase gamma (NxrC) for electron conservation. In particular, a tubule-inducing nitrite oxidoreductase subunit (NxrT homologue) was further formed for electron transformation after the Neoproterozoic Oxygenation Event (NOE). Finally, based on two full-scale anammox-based wastewater treatment systems (WWTPs), we identified core gene transcriptional activities affecting the abundance of the family Ca. Brocadiaceae and their association with environmental factors. Overall, our study not only provides key information for understanding the dynamic patterns and evolutionary mechanisms of the anammox reactions and the associated electron transfers in conjunction with major geological events, but also provides new insights for future enrichment and effective applications.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"30 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results reveal that &gt;20 % of the sites exhibit relatively high long-term average salinity levels compared to the irrigation water threshold, primary in arid or semi-arid regions experiencing intensified human activities.

Winter salinity levels and their rate of increase surpass those of other seasons. Anthropogenic drivers, particularly population density and agricultural water use, emerge as key contributors to rising salinity, in conjunction with hydroclimatic variables.

Although the molecular mechanisms governing plasmid replication, maintenance, and transfer have been extensively studied, the specific impacts of urbanization-induced pollution on plasmid ecology, diversity, and associated ARGs in tropical regions remain underexplored. This study investigates these dynamics in a tropical aquatic ecosystem, providing novel insights into how pollution shapes plasmid composition and function. In contrast to the observed decrease in chromosomal diversity, we demonstrate that pollution associated with urbanization increases the diversity and taxonomic composition of plasmids within a bacterial community (plasmidome). We analyzed eighteen water and sediment metagenomes, capturing a gradient of pollution and ARG contamination along a tropical urban river. Plasmid and chromosomal diversity profiles were found to be anti-correlated. Plasmid species enrichment along the pollution gradient led to significant compositional differences in water samples, where differentially abundant species suggest plasmid maintenance within specific taxonomic classes. Additionally, the diversity and abundance of ARGs related to the plasmidome increased concomitantly with the intensity of fecal and chemical pollution. These findings highlight the critical need for targeted plasmidome studies to better understand plasmids' environmental spread, as their dynamics are independent of chromosomal patterns. This research is crucial for understanding the consequences of bacterial evolution, particularly in the context of environmental and public health.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"21 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the metabolic dynamics of photogranules to varying nutrient and light conditions in wastewater treatment systems remains poorly studied. However, understanding how quickly the photogranule metabolism changes, and whether this change is temporary or permanent is important for the optimal use of photogranules. Here, an NMR-based metabolomics approach was applied to investigate the temporal dynamics of photogranule metabolism in the presence or absence of acetate and with or without light.Our findings revealed that under carbon-limited conditions, photogranules relied on alternative carbon sources, such as N-acetylneuraminate (a constituent of EPS) and amino acids like hypotaurine and L-alanine. This adaptation affected key metabolic pathways, including glycolysis, taurine and hypotaurine metabolism, and the tricarboxylic acid cycle. When acetate was provided, both heterotrophic and phototrophic activities were maintained. Notably, the history of carbon supply influenced how photogranules responded to light shifts. Metabolic indicators showed that the lag in carbon addition altered fatty acid metabolism and carbon fixation, leading to shifts in amino acid concentrations and distinct metabolic profiles when the light was turned off. Thus, NMR metabolomics identified metabolic changes, induced by contrasting carbon conditions, lasting for several hours, and significantly affecting the photogranule response to light fluctuations. These results suggest that the history of carbon supplementation may shape metabolic responses of photogranules to other environmental changes or stressors.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"12 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the impact of biochar addition on the removal of organic micropollutants (OMPs) in field-scale biofilters operating under real-world conditions for the first time. The research comprised four vegetated biofilter facilities (3−5 years old), two without and two with 2.1 <em>wt.</em>% (10 <em>vol.</em>%) biochar amendment. Stormwater and filter material samples from various locations after four years of operation were analyzed for a wide range of common and emerging OMPs found in urban runoff. Unlike hydrophobic OMPs (hydrocarbons, polychlorinated biphenyls, and di(2-ethylhexyl) phthalate), the investigated biofilters demonstrated low, or inconsistent, removal of hydrophilic and slow-adsorbing OMPs like bisphenol A, monobutyltin, and per-fluoroalkyl substances (PFASs). Although the physiochemical properties of biochar were well-adapted to pollutant removal, biochar amendment did not significantly improve OMP removal when compared with the status quo. This can be attributed to several field conditions and suboptimal design interfering with the biochar's sorption capacity, namely, the large particle size (D₅₀ ∼4 mm) and low quantity of biochar, high levels of competing agents (i.e., dissolved oxygen carbon (DOC) and cations), co-contaminants in stormwater, limited contact time, biochar pore blockage (e.g., by DOC molecules and sediments/minerals), diminished biochar surface porosity, and sometimes increased removal uncertainty due to low influent concentrations. Our findings demonstrated the complexities associated with applying biochar for stormwater treatment. Further research on biochar-specific biofilter designs is needed to optimize the sorption potential of this material under field conditions.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"183 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143695691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
