Abstract ：
Bio-denitrification is vital in wastewater treatment plants (WWTPs), yet its integration with naturally abundant thermal energy remains unexplored. Here, we introduce a biohybrid-based pyroelectric bio-denitrification (BHPD) process that harnesses thermoelectric energy from ambient temperature fluctuations. By integrating Thiobacillus denitrificans with tungsten disulfide (WS2), we develop a biohybrid system that achieves complete denitrification over three 5-day cycles under 5 degrees C temperature fluctuations. WS2 either precipitates on the cellular surface or is internalized by cells, generating pyroelectric charges that serve as reducing equivalents to drive bio-denitrification. In real wastewater, the BHPD process enhances nitrate removal by up to 8.09-fold under natural temperature fluctuations compared to stable-temperature conditions. Life-cycle assessment demonstrates that the BHPD process has significantly lower environmental impacts than the conventional anaerobic-anoxic-oxic process, and cost analysis confirms its economic feasibility. Our findings highlight the potential of the pyroelectric effect in enhancing bio-denitrification, offering valuable insights for a paradigm shift in WWTPs.

Abstract ：
Phototrophy and chemotrophy are two dominant types of microbial metabolism.However,to date,the potential of the ubiquitous and versatile mechanical energy as a renewable energy source to drive the growth of microorganisms has remained unknown and not utilized.Here,we present evidence in favor of a previously unidentified metabolic pathway,in which the electronic energy produced from mechanical energy by the piezoelectric materials is used to support the growth of microorganisms.When electroactive microorganism Rhodopseudomonas palustris(R.palustris;with barium titanate nanoparticles)was mechanically stirred,a powerful biohybrid piezoelectric effect(BPE)enabled sustain-able carbon fixation coupled with nitrate reduction.Transcriptomic analyses demonstrated that mechanical stirring of the bacteria-barium titanate biohybrid led to upregulation of genes encoding functions involved in electron and energy transfer in R.palustris.Studies with other electroactive microorganisms suggested that the ability of microbes to utilize BPE may be a common phenomenon in the microbial world.Taken together,these findings imply a long-neglected and potentially important microbial metabolic pathway,with potential importance to microbial survival in the energy-limited environments.

Abstract ：
The urgent need to address the high prevalence of waterborne diseases in underdeveloped regions necessitates the development of economically viable, decentralized, and sunlight-assisted disinfection techniques. An encouraging solution lies in the utilization of photosynthesized H2O2 to initiate advanced oxidation processes (AOPs). However, challenges persist in the quest to develop efficient photocatalysts and reactor designs. Herein, we present the rational design and synthesis of a metal-free supramolecular photocatalyst achieved via the postfunctionalization of fluorine-substituted covalent organic frameworks (FCOFs) with polyvinylpyrrolidone (PVP). The resulting FCOF/PVP composite establishes intermolecular C-F center dot center dot center dot C=O interactions at the interface, which facilitate accelerated charge separation and transfer, as well as promote efficient intersystem crossing to enhance the formation of molecular triplet excitons. These photophysical enhancements enable dual-pathway H2O2 generation mediated by superoxide radicals (center dot O2-) and singlet oxygen (1O2), yielding a H2O2 production rate of 1763.50 mu mol/g/h from pure water and atmospheric oxygen. The photosynthesized H2O2 is subsequently catalyzed by Fe(II) to generate hydroxyl radicals (center dot OH), achieving effective inactivation of pathogenic bacteria and viruses. A continuous-flow system was further developed to couple photocatalytic H2O2 production with Fenton disinfection, combining the benefits of heterogeneous and homogeneous catalysis while addressing limitations in photocatalyst recovery and light dependency. This system exhibited robust disinfection performance under real water matrices and intermittent light conditions. Economic analysis supports the feasibility of the system for deployment in resource-limited settings, offering a novel material-based approach for decentralized water treatment and global efforts to mitigate waterborne diseases.

Abstract ：
A novel electric field-assisted aerobic composting (EAC) method effectively facilitates compost disposal by applying a low electric field to conventional aerobic composting (CAC). The humification effect of inoculation with Bacillus clausii in the EAC system was better than that in the CAC system, so this study focused on the enhancement effect of microbial inoculation in the EAC system. Compared with EAC, EAC with microbial inoculation (AMI-EAC) increased the degradation of cellulose, hemicellulose, and lignin. Furthermore, AMI-EAC improved the humification index by 42.89 % relative to EAC. AMI-EAC also increased the relative abundance of Bacillus, enriched thermophilic and electroactive microorganisms, and enhanced the activity of associated degradative enzymes, which promoted the decomposition and humification of organic matter. Partial least squares-path model analysis showed that Bacillus inoculation during AMI-EAC enhanced the direct positive effect of microorganisms on enzyme activity and strengthened the positive impacts of substance degradation and enzyme activity on compost maturation. This study provided new insights for inoculating microbial agents to enhance composting efficiency in future engineering applications of EAC.

Abstract ：
Nanobiohybrids for solar-driven methanogenesis present a promising solution to the global energy crisis. However, conventional semiconductor-based nanobiohybrids face challenges such as limited tunability and poor biocompatibility, leading to undesirable spontaneous electron and proton transfer that compromise their structural stability and CH4 selectivity. Herein, we introduced eutectic gallium-indium alloys (EGaIn), featuring a self-limiting surface oxide layer surrounding the liquid metal core after sonication, integrated with Methanosarcina barkeri (M. b). The well-designed M. b-EGaIn nanobiohybrids exhibited superior performance, achieving a maximum CH4 yield of 455.64 +/- 15.99 mu mol g(-1), long-term stability across four successive 7-day cycles, and remarkable CH4 selectivity of >99 %. These improvements stem from enhanced proton-coupled electron transfer involving hydrogen atoms at the core-shell interface, further facilitated by the elevated expression of hydrogenases at the abiotic-biotic interface. This study provides an insightful concept for nanobiohybrid design through multi-interface engineering, advancing sustainable and scalable CO2-to-biofuel conversion under ambient conditions.

Abstract ：
Evaporation-induced electricity is a hydrovoltaic technology that uses water evaporation to generate electricity, and has attracted attention due to its highly self-generating and sustainable electricity production capability. Hydrogels, which are rich in hydrophilic functional groups and have good water transport properties, are considered as promising functional materials for evaporation-induced electricity generation. However, the preparation of traditional hydrogels usually requires heating or ultraviolet-induced polymerization, which is a complicated and time-consuming process, severely limiting the practical application of hydrogel-based hydrovoltaic technology. Herein, Geobacter sulfurreducens (G. s) was used as a model microorganism to induce the rapid polymerization of nanocellulose and polyacrylamide macromolecular chains at room temperature, which resulted in the synthesis of a biohydrogel film with excellent performance within one minute. The abundance of reducing functional groups in G. s reacted with S2O82− in a spontaneous redox reaction, releasing heat and free radicals, which accelerated the polymerization reaction. Owing to the excellent electrical conductivity of G. s, the G. s biohydrogel film has both excellent charge transfer capability and mechanical properties, which is beneficial for the application of aqueous hydrovoltaic devices. The evaporation generator assembled by G. s biohydrogel film can output ~13 μA of current for a long time, which can be used to power small electronic devices. In conclusion, the present study provides an energy-saving, simple, and rapid method for the preparation of biohydrogel film, which provides a new choice for the key functional materials of hydrovoltaic technology and practical application. © 2025 Science Press.

Abstract ：
The biophotoelectrochemical process (BPECs) integrates the light-absorbing capabilities of nano-semiconductors with the catalytic efficiency of microorganisms, demonstrating significant potential for the development, utilization, transformation, and ecological restoration of water resources. In aquatic environments, extracellular polymeric substances (EPS) serve as a critical interfacial barrier between microorganisms and semiconductor materials, with the underlying electron transfer mechanisms playing a pivotal role in determining the efficiency of bio-photochemical reactions. Despite their importance, the rapidity and complexity of the electron transfer process within EPS pose significant challenges to a comprehensive understanding of BPECs. In this study, an in- situ characterization strategy was employed to rapidly and accurately analyze the components and pathways of photogenerated electron transfer involving EPS at interfaces. The findings indicate that EPS significantly accelerates the transfer of photogenerated electrons within BPECs. Specifically, proteins and redox-active substances within EPS act as efficient conduits for electron transfer, accounting for up to 84.2% of the increased speed in electron transfer rates at bio-abiotic interfaces. Conversely, polysaccharides within EPS impede the electron transfer process but serve as substrates that facilitate methane (CH4) production. The in-situ characterization approach used in this research provides valuable insights into the interfacial electron transfer mechanisms of EPS in BPECs, emphasizing their relevance in aquatic environments. This study establishes a theoretical framework for designing high-performance BPECs, with significant implications for the energy utilization of water resources and the transformation of water pollutants.

Abstract ：
非光合微生物的光电营养代谢途径在生态系统能量循环中发挥着重要作用。海洋透光层具有自然光可及、物质能量交换剧烈和生化过程活跃等触发光电营养代谢的基本条件，但其内部光敏物质和微生物的光电响应机制仍未得到充分研究。本研究解析了闽江入海口河口、近岸和近海区域透光层中光敏物质的组成与空间分布、光电响应以及微生物群落结构。结果表明，这3个区域均存在悬浮半导体颗粒、天然色素和溶解性有机质等光敏物质，且其含量随着离岸距离增加而逐渐下降，但近岸区域光合微生物的丰度最高。光电流实验结果显示，近岸区域的光电效应最为显著，可能是由于其具有较为丰富的光敏物质和较少的共存物质干扰。微生物群落分析结果表明，海洋透光层中的微生物群落结构表现出显著的光电响应特征，其中电活性微生物的丰度与光敏物质含量呈显著正相关，表明电活性微生物的分布与光敏物质高效光电转化的区域高度一致。因此，天然光敏物质与电活性微生物之间的光电协同作用，有可能为理解海洋碳、氮等元素的生物地球化学循环提供新的理论视角。
