Traditional static linear calibration fails to separately quantify three distinct inhibitory pathways, including physical shielding of electroactive biofilms by HA, intracellular cytotoxicity induced by free Cu, and additional signal attenuation derived from insoluble HA-Cu chelated precipitates. In this study, a dual‑functional constructed wetland‑microbial fuel cell (CW‑MFC) system was developed for real‑time water quality sensing and synchronous pollutant remediation. A three-parameter hierarchical Bayesian inversion framework incorporating three independent weighting coefficients (γ_HA, γ_Cu and γ_HA-Cu) was established to mathematically decouple multi‑source signal drift under HA-Cu combined contamination. With real‑time Bayesian drift compensation, the concentration‑domain root‑mean‑square error (RMSE) was reduced to 8.77 ± 0.71 mg/L for HA and 0.78 ± 0.06 mg/L for Cu under HA-Cu pollutant conditions. The integrated CW‑MFC system achieved over 85 % chemical oxygen demand (COD) removal, demonstrating its dual capacity for self‑powered real‑time water quality monitoring and decentralized water purification.

This study compared the performance of a conventional aerated algal-bacterial biofilm reactor (CAABR) and a membrane-aerated algal-bacterial biofilm reactor (MAABR) for AMD treatment. Six reactors with different influent COD concentrations (400 ± 11.41, 1400 ± 19.07, and 2800 ± 18.37 mg/L) were operated for 80 days, and pollutant removal, biofilm properties, and microbial community dynamics were systematically analyzed. Results showed that the MAABRs and CAABRs exhibited broadly comparable sulfate-removal performance, whereas the MAABRs maintained greater aqueous DIC availability and more stable heavy-metal removal under shock loading. Kinetic analysis revealed a transition from algal assimilation (first-order) to SRB-mediated reduction (zero-order) as COD increased, confirming that COD/SO₄^2- ratios regulate pathway dominance. Multiscale biofilm characterization and EPS fluorescence analysis demonstrated that membrane aeration improved CO₂/O₂ mass transfer, enhanced algal biomass, and maintained higher EPS secretion under stress. High-throughput sequencing revealed the simultaneous enrichment of Pseudomonas and the sulfate-reducing genus Desulfosporosinus, indicating that the MAABR supported the coexistence of functionally distinct microbial populations.

To enable direct starch utilization, a strain capable of both amylase secretion and BC production was constructed. A sterilization-free fermentation process using raw SPW without an external carbon source was subsequently established and scaled from 120 mL to a 6 L working volume in a 10 L fermenter. Within 24 h, the process produced 871 ± 13 g/L wet SPW-derived BC (SPW-BC), while reducing wastewater volume, suspended solids, starch, and chemical oxygen demand by 87.17%, 98.09%, 84.60%, and 61.25%, respectively.

SPW-BC also enhanced soil nutrient availability and promoted lettuce growth, with the seedling vigor index reaching 0.69 ± 0.08.

The control reactor showed pronounced deterioration at 4.0-5.0 g COD/L/d, and its operation was terminated at 6.0 g COD/L/d. In contrast, the magnetite-amended reactor maintained methane yields near 300 mL CH₄/g COD_added through 6.0 g COD/L/d and remained operational at 8.0 g COD/L/d. At 6.0 g COD/L/d, total residual organic acids reached 2,675 ± 338 mg COD/L in the control reactor but only 709 ± 35 mg COD/L in the magnetite-amended reactor. Propionate in the magnetite-amended reactor remained below 89 mg COD/L during the higher loading stages. The persistent distribution of Fe-bearing material within the granule matrix, consistent with magnetite retention, coincided with sustained granule size, more coherent EPS-associated spectral responses, a smaller increase in humic- and fulvic-like fluorescence, stronger electrochemical responsiveness, and higher electron transport system activity. Metagenomic profiles further showed that methanogenic taxa and genes related to EPS biosynthesis, redox metabolism, and methanogenesis persisted to higher OLRs in the magnetite-amended reactor. Acetate accumulation at the highest OLR indicated that magnetite delayed rather than prevented the eventual limitation in acetate conversion.

Targeted genetic manipulation revealed that MpSir overexpression increased AD yield by 13.28% (to 83.24%), and MpKat knockout improved yield by 8.86%, while MpKat overexpression decreased yield by 8.69%. Reducing global acylation levels alleviated oxidative stress, elevated NAD⁺/NADH ratios, enhanced phytosterol tolerance, and improved cell viability. In repeated-batch fermentation, the MpSir-overexpressing strain achieved an average AD yield of 76.5% with a 51% reduction in fermentation time compared to the wild type.

This study selected polylactic acid microplastics (PLA-MPs) as model biodegradable microplastics to investigate their effects on nitrous oxide (N₂O) emissions from a mainstream biological nitrogen removal system. Long-term exposure to PLA-MPs at environmentally relevant level (0.5 mg/L) increased the N₂O emission factor by 28.9%, and inhibited maximum nitrification and denitrification activities by 13.4%-20.9% and 4.9%-16.7%, respectively, while the nitrate reduction rate increased by 9.9%. Under elevated stress (5 mg/L), the N₂O emissions increased by 32.4%, but the extent of maximum activity inhibition was comparable to that at 0.5 mg/L. Isotopic analysis revealed that PLA-MPs promoted the NH₂OH oxidation pathway and consequently enhanced the N₂O-producing capacity of nitrifiers, while nitrite accumulation during nitrification remained largely unaffected. During denitrification, however, PLA-MPs disrupted the balance of nitrogen oxide reduction steps, leading to elevated accumulation of both nitrite and N₂O. PLA‑MPs altered the composition and structure of extracellular polymeric substances, which was accompanied by increased sludge particle size and hydrophobicity. Concurrently, shifts in the relative abundances of key microorganisms and enzyme-encoding genes involved in electron transfer, electron consumption, and metal transmembrane transport were observed.
