Physical barriers like head works, dams barrages are main cause of fragmentation and declining of freshwater fish population in natural habitat. Present study focused on RAPD marker technique to assess the genetic variability among and between the populations of endangered sperata sarwari (Singharee) inhabited in the Indus drainage system of Punjab. Total eight populations (80 speciemen) of S. sarwari were collected from the up and downstream of four Rivers (Chenab, Jhelum, Ravi and Indus) of Punjab. Genomic DNA isolated from muscle tissue of adipose side and ten RAPD marker were used, which produced 50 scorable bands with average band ranging from 250–1050 bp which used for further genetic analysis of S. sarwari. Downstream Indus population of S. sarwari showed highest values of observed alleles (na), effected alleles (ne), Nei’s diversity (h), Shannon index (I) and polymorphism which indicated that downstream Indus population was more genetically variant. The genetic variability (0.5124) and genetic flow (0.4758) among the eight population S. sawari was observed. The up and downstream population showed the highest genetic distance (0.5738) and lowest genetic similarities (0.5634) which indicated complete isolation of Ravi population from other six population. Dendrogram showed that up and downstream Ravi population was completely isolated from the other six up and down stream population of S. sarwai. Overall results indicated that the presence of high fragmentation in River Ravi caused the destruction of habitat and decline in population of S. sarwai in the River Ravi. © 2021, CC BY.

Fenton process is one of the widely used advanced oxidation processes, but its application is mainly limited by its narrow working pH range (pH 2.0-4.0). In this work, we observed the unexpected degradation of tetracyclines (TCs) in the Fenton process under near-neutral pH conditions without introducing extra energy or chemicals. We found that TCs could be effectively degraded in the Fenton process at pH 5.0-7.0, although other organic contaminants, such as phenol and acetaminophen, were hardly degraded under the same conditions. Multiple lines of evidence, including UV-spectra, H NMR spectra, calculation of complexation constants, and analysis of transformation products, revealed that the complexation of Fe(II) with TCs played a crucial role in driving the degradation of TCs in this process and that the BCD ring of TCs was the key structure. Moreover, the degradation of TCs was attributed to the Fe(Ⅱ)-TCs complex-induced electron transfer between HO and TCs during this process under near-neutral pH conditions. Additionally, the degradation of TCs in this process was not sensitive to interference from the water matrix. The findings of this study provide new insight into the development of wastewater treatment technologies based on the properties of organic contaminants.

Enhancement in denitrification rate with reduced intermediates accumulation has been a great challenge for nitrogen removal from wastewater. In this paper, it was found that the denitrification performance of two denitrifiers, Paracoccus denitrificans and Pseudomonas denitrificans, were both improved in the presence of Shewanella oneidensis MR-1. Data showed the introducing of S. oneidensis MR-1 promoted nitrate reduction rate by 40.3%–50.0% in Par. denitrificans reactors. Meanwhile, it also increased nitrite and nitrous oxide reduction rates by 32.5%–111.0% and 68.8%–694.0% respectively in Pse. denitrificans reactors. Further investigation illustrated S. oneidensis MR-1 generally increased the electron competition capability of nitrogen oxide (NOx) reductases in varying degrees. As the electron distribution to the downstream NOx reductases increased more than that of the upstream ones, it led to reduced intermediates accumulation. Finally, the effectiveness of S. oneidensis MR-1 on augment denitrification performance was also validated in carbon-limited condition. © 2020 Elsevier Ltd

The CO2 bioelectromethanosynthesis technology holds tremendous potential to solve the energy crisis and mitigate the greenhouse effect. However, membrane contamination in MEC (microbial electrolytic cells) reactors is still crucial for long-term economic performance. This study presents a breakthrough solution by introducing a biogas circulation unit in the cathode chamber. This not only effectively prevented membrane fouling, but also resulted in a remarkable increase in the cathodic methane production rate from 0.4 mL/L.d to an impressive 8.5 mL/L.d. The design offered other benefits such as improved mass transfer, homogenized catholyte, and reduced concentration polarization. The syntrophic and symbiotic relationship between various microorganisms in the anodic and cathodic compartments, including anodic Firmicutes (65.29%), Bacteroidetes (25.90%), Proteobacteria (6.08%) and cathodic Methanobacterium (65.58%) to a robust microenvironment that enabled simultaneous organic degradation, CO2 bioelectromethanosynthesis, and energy storage. © 2023, The Authors.

Photoelectrochemical (PEC) water splitting is a promising technology for green hydrogen production. However, severe charge recombination at the photoanode has impeded its advancement. Incorporating co-catalyst on bismuth vanadate (BiVO 4 , BVO) photoanode could enhance the charge transfer efficiency and accelerate the surface reaction kinetics, which are two key challenges in the PEC system. Herein, NiFeO x co-catalyst is deposited on BVO (NiFeO x -BVO), enhancing the performance to 3.3 times (3.57 mA cm −2 at 1.23 V vs. RHE) in comparison to the pristine BVO. A systematic analysis has been engaged to unravel the individual roles of Ni and Fe in enhancing the PEC performance of NiFeO x -BVO. While the Ni enhances the charge transfer of BVO, the Fe is found to accelerate the water oxidation kinetics at the surface of photoanode. Working synergistically, the NiFeO x enhanced bulk (72.2 %) and surface (76.4 %) charge transfer efficiency compared to the pristine BVO (55.1 % and 30.5 %, respectively), measured at 1.23 V vs. RHE. This work provides important insights into rationally designing the cocatalysts for efficient PEC water splitting.

The increasing prevalence of short-chain per- and polyfluoroalkyl substances (PFASs) poses significant challenges for urban water systems (UWS) due to their persistence, high mobility, and widespread occurrence. This study provides a comprehensive assessment of the occurrence, environmental transport, influencing factors, removal efficiency, and human health risks of PFASs across UWS impacted by industrial activities. Regulatory restrictions on long-chain PFASs have led to their replacement with short-chain analogues, resulting in their dominance in effluents from manufacturing plant parks (MPPs), with concentrations ranging from 30.28 to 3738.51 ng/L (mean: 557.68 ± 1072.03 ng/L). Wastewater treatment plant (WWTP) serve as both sources and sinks of PFASs, with a negative average removal efficiency (–47.4 %) and an estimated annual discharge of 12.29 kg of PFASs into the environment. Downstream of WWTP, PFASs concentrations in rivers decrease exponentially due to dilution and sediment partitioning; however, short-chain PFASs persist over long distances due to their high aqueous mobility. While the detected PFAS levels in rivers pose low health risks to humans, they present low to medium ecological risks to aquatic organisms, particularly algae, invertebrates, and fish. Advanced statistical analyses using piecewise structural equation modeling (piecewiseSEM) and co-occurrence network analysis (CNA) identified key environmental drivers of PFASs behavior, including heavy metals (effect size: 0.70), nutrient levels (0.36), and physicochemical parameters (–0.52). Furthermore, drinking water treatment plants (DWTPs) demonstrated limited removal efficiency, with tap water concentrations ranging from 27.95 to 84.72 ng/L, exceeding the regulatory limits set by the US EPA (2022) (PFOA: 0.004 ng/L, PFOS: 0.02 ng/L) and Health Canada (Σ 25 PFAS: 30 ng/L). These findings underscore the urgent need for enhanced regulations, the development of sustainable alternatives, and the imp

Bacteriophages (phages) are vital components in biological wastewater ecosystems, whose concentrations are far exceeding those bacteria. Despite their importance, they are often overlooked and regarded as the "dark matter" in biological treatment processes. Phages play a pivotal role in shaping the dynamic evolution of host microbial communities within wastewater treatment plants (WWTPs), driving their functional evolution through interactions with host microorganisms. Phages are crucial in driving microbial ecological dynamics and regulating metabolic functions. At the macroscopic scale, the organic matters released through viral shunting demonstrate enhanced bioavailability and facilitated organic element cycling based on viral shuttle-mediated bio-pump. Additionally, at the micro-scale, gene transfer mediated by phages can assist functional microorganisms in enhancing metabolic efficiency and adapting to environmental stress. However, this process also introduces environmental risks, particularly the dissemination of antibiotic resistance genes through horizontal gene transfer and plasmids. Phages offer distinct advantages over conventional chemical and physical methods, including superior efficiency and environmental sustainability. Nonetheless, the development of phage-based biocontrol strategies is constrained by phage specificity and the complexity of biological treatment systems. Recent advances in artificial intelligence and genetic technologies provide promising avenues for optimizing phage applications. Further research into phage ecology is essential to lay a theoretical foundation for enhancing operational stability, treatment efficiency, and targeted biocontrol strategies.

A new strategy for preparing highly dispersed, richer oxygen vacancies Ni/ZrO 2 catalysts derived from UiO-66-NH 2 is reported via pyrolysis-calcination removal of the ligands under N 2 , CO 2 , and Air atmospheres followed by loading Ni with 5 wt.% via wet impregnation method. Subsequently, the low-temperature dry reforming of methane (DRM) reaction over the obtained Ni/ZrO 2 catalysts was preliminarily investigated. The results indicated that the Ni/ZrO 2 -C catalyst, obtained by two-step pyrolysis in CO 2 , contained smaller Ni particles with a size of only 5-7 nm and possessed a hierarchical porous structure, as well as richer oxygen vacancies and basic active sites compared to the other two catalysts. Its catalytic activity in the DRM reaction presented the highest initial conversion of CH 4 (35 %) and CO 2 (26 %) at 600 °C, which was 5 % higher than that of the Ni/ZrO 2 -N and Ni/ZrO 2 -O catalysts obtained by two-step pyrolysis under an N 2 atmosphere and one-step pyrolysis under an air atmosphere, respectively. Meanwhile, an in-situ DRIFTS experiment revealed that Ni/ZrO 2 -C could enhance the adsorption and activation of CO 2 by promoting the formation of formate as an intermediate of CO hydrogenation and reverse water-gas shift (RWGS) reactions, which in turn facilitates the decomposition of CH 4 .

A stable solid-electrolyte interphase (SEI) is crucial for cycling reversibility of Na-ion batteries by mitigating continuous side reactions. So far, the severe SEI dissolution leads to low Coulombic efficiency (CE) and short cycle life. Meanwhile, the quantified relationship between SEI components and their solubility remains unclear. In this work, we establish the direct correlation between SEI components and SEI solubility, and quantify that the solubility of organic-rich SEI is 3.26 times of inorganic-rich SEI. We further propose a feasible strategy to preform inorganic-rich insoluble SEI and demonstrate a practical hard carbon (HC)||NaMn 0.33 Fe 0.33 Ni 0.33 O 2 full cell in a commercial electrolyte of 1 M NaPF 6 in propylene carbonate (PC) with 80.0 % capacity retention for 900 cycles, and achieve a record-high average CE of 99.95 % for a practical Na-ion full cell. This study provides an effective strategy of preforming insoluble SEI to suppress its dissolution towards highly reversible Na-ion batteries.
