However, the chemicals released, particularly during long-term water or wastewater filtration, are highly toxic to the environment and humans. Herein, an herb-inspired, green antibacterial membrane with exceptional sustainable antifouling properties was developed using aloin. The resultant membranes exhibited excellent bacterial inactivating efficiency because of the electrostatic interactions between the amine groups on the membrane and the bacterial cells, which contributed to cell deformation. The aloin molecules also significantly increased reactive oxygen species levels, causing oxidative damage to bacterial cells. Moreover, the functional decorative layer, which exhibited remarkable resistance to bacterial adhesion because of the abundant hydroxyl, carbonyl, and amino groups in aloin, endowed the as-prepared membranes with strong polarity, reducing bacterial adhesion and biofilm formation. When applied in a membrane bioreactor, the aloin-modified membranes demonstrated a >27.0% lower fouling rate than commercial microfiltration membranes. Overall, the successful fabrication strategy and material features described offer a green alternative for membrane development and provide new avenues for the design of healthcare materials such as wound dressings.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"59 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640264","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 presents a steady-state metabolic model integrating anaerobic amino acid (AA) fermentation and storage processes in fPAOs. The model identifies key metabolic interactions underlying fPAO metabolism, prioritising substrate accumulation over fermentation. This results in significant changes to ATP and reduction-oxidation (redox) flows as compared to when relying on previous AA fermentation models typically used to describe fPAO metabolism, with medium-chain-length (MCL) polyhydroxyalkanoate (PHA) formation and polyphosphate (polyP) consumption acting as important electron and energy management mechanisms, respectively. Succinate, rather than volatile fatty acids (VFAs), was identified as the more likely synergetic substrate between fermentative and conventional PAOs (cPAOs) under these conditions. Moreover, conditions favourable of VFA efflux by fPAOs may also favour a shift away from a polyP accumulation to a fermentation dominant metabolism. Further work is required to verify the role of MCL-PHA fractions, alongside the contribution of free intracellular AA accumulation as compared to polymers such as cyanophycin or polyglutamate on fPAO metabolism. This metabolic model provides a framework for better understanding the role of fPAOs and their interactions with cPAOs within EBPR processes, informing future modelling and optimisation of F-EBPR systems.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"189 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640260","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}

As climate change and anthropogenic activities alter hydrology and salinity worldwide, understanding microbial ecology and metabolism becomes increasingly important for managing aquatic ecosystems. Biogeochemical processes were investigated on sediment microbial communities during a significant flood event in the hypersaline Coorong lagoon, South Australia (the largest in the Murray-Darling Basin since 1956). Samples from six sites across a salinity gradient were collected before and during flooding in 2022. To assess changes in microbial taxonomy and metabolic function, 16S rRNA amplicon sequencing was employed alongside untargeted liquid chromatography–mass spectrometry (LC-MS) to assess changes in microbial taxonomy and metabolic function. Results showed a decrease in microbial richness and diversity during flooding, especially in hypersaline conditions. Pre-flood communities were enriched with osmolyte-degrading and methanogenic taxa, alongside osmoprotectant metabolites, such as glycine betaine and choline. Flood conditions favored taxa such as <em>Halanaerobiaceae</em> and <em>Beggiatoaceae</em>, inducing inferred metagenomic shifts indicative of sulfate and nitrogen reduction pathways, while also enriching a greater diversity of metabolites including Gly-Phe dipeptides and guanine. This study demonstrates that integrating metabolomics with microbial community analysis enhances understanding of ecosystem responses to disturbance. These findings suggest microbial communities rapidly change in response to salinity reductions while maintaining key biogeochemical functions. Such insights are valuable for ecosystem management and predictive modelling under environmental stressors such as flooding.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"197 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640120","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}

By utilizing modulators with varying pKa values-specifically benzimidazole (BI), benzoic acid (BA), and acetic acid (AA)-we synthesized defect-rich Act-UiO-66-M(X). The higher pKa of BI facilitated greater defect formation, resulting in significantly improved adsorption capacity and faster diffusion rates. Act-UiO-66-BI(8), modulated with BI, showed a higher intensity peak at g = 2.003 in ESR analysis, indicating more oxygen vacancies. Its fluoride adsorption capacity reached 93.59 mg F/g, nearly six times higher than commercial ZrO₂, with rapid kinetics—evidenced by a kinetic rate constant (k_int) of 2.64 mg/g·min^0.5 and equilibrium achieved within 10 minutes. The kinetic performance was enhanced by 270% compared to raw Act-UiO-66. Furthermore, Act-UiO-66-BI(8) demonstrated high selectivity and stability in high-salinity environments, with a K_d coefficient consistently exceeding 17,900 mL/g. The study highlights that selecting modulators based on pKa enhances defect formation, improving active site exposure and pore diffusion, as confirmed by DFT calculations and XPS analysis. The ability of Act-UiO-66-BI(8) to treat up to 1160 kg of wastewater per kg of adsorbent highlights its potential for large-scale water purification, showcasing a promising approach for developing high-performance MOF materials.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"69 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635596","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}

Metagenomic analysis presents a powerful approach to elucidate community-level metabolic differences between EBPR and S2EBPR configurations. In this study, we compared three EBPR and three S2EBPR activated sludge communities using metagenomic analysis at taxonomy, key functional pathways/genes, and polyphosphate-metabolism marker genes. Our analysis revealed larger genus-level diversity variance in S2EBPR communities, indicating distinct microbial community compositions influenced by different operational configurations. A higher diversity index in the S2EBPR than the EBPR was observed, and a higher <em>Ca.</em> Accumulibacter abundance was detected in EBPRs, whereas the fermentative candidate PAOs genera, including <em>Ca.</em> Phosphoribacter and <em>Ca.</em> Promineifilum, were more abundant in S2EBPR systems. EBPR and S2EBPR groups displayed similar gene and pathway abundance patterns related to core metabolisms essential for carbon and nitrogen metabolism. PolyP-metabolism marker gene phylogeny analysis suggested that exopolyphosphatase gene (<em>ppx</em>) showed better distinctions between EBPR and S2EBPR communities than polyphosphate kinase gene (<em>ppk</em>). This also highlighted the needs in fine-cale microdiversity analysis and finding novel <em>Ca.</em> Accumulibacter clades and species as resolved using the <em>ppk</em> gene.

The experimental results demonstrated that S(IV)/Fe(VI)-UF showed superior purification performance and UF membrane fouling mitigation than Fe(VI)-UF. S(IV)/Fe(VI)-UF achieved removals of sulfamethoxazole, DOC, and UV₂₅₄ up to 77.73%, 61.86%, and 86.33%, and was able to significantly mitigate UF membrane fouling by prolonging the transition stage and positively shifting the interfacial free energy. Innovatively, the absence of a sedimentation unit was found to adversely affect the initial stages of Fe(VI)-UF and S(IV)/Fe(VI)-UF by lowering the energy barriers, while negligibly affecting cake filtration. Additionally, the water treatment cost of S(IV)/Fe(VI) was 0.3 yuan per ton, indicating notable economic benefits and engineering potential.

This study investigates the metabolism of higher order (C_4-5) volatile fatty acids (VFAs) in F-EBPR systems using a combination of carbon isotope labelling and shotgun metagenomic sequencing analyses. Results show that butyrate (HBu) uptake leads to the formation of both typical (C_4-5) and atypical (C₆₊) polyhydroxyalkanoates (PHAs) through a combination of β-oxidation and standard condensation pathways, while the putative role of HBu oxidisers were identified relative to substrate composition in F-EBPR processes.

This pilot study was conducted in a tertiary step-feed moving bed biofilm reactor (MBBR) over 478 days, using full-scale HRAS secondary effluent as the influent. Unlike most PdNA applications that rely on the expensive supplemental carbon like methanol or glycerol, this study is the first to demonstrate that PE carbon can be utilized as a naturally available carbon source within wastewater to drive PdNA. By taking advantage of this free internal carbon source to driven PdNA, 63% to 74% savings in PE carbon consumption and ∼36% offset in glycerol consumption were achieved. Additionally, glycerol-driven PdNA further reduced both supplemental carbon and aeration energy demands by 70% and 18%. Mechanistic insights from in-situ and ex-situ batch tests revealed that the PE-driven PdNA was facilitated by an anammox-driven nitrite sink, a novel observation that allowed stable PdNA performance without nitrite accumulation. Furthermore, batch tests indicated that endogenous respiration could support PdNA. These findings highlight the potential of applying PE-driven PdNA in full-scale facilities, ushering in a new era of mainstream anammox applications in wastewater treatment, as PdNA is no longer reliant on costly external carbon addition.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"34 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631189","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}
