Abstract ：
Microbial biofilm-based hydrovoltaic electricity generators (BioHEGs) have recently been developed as promising and readily available platforms for green energy harvesting, despite their unsatisfactory output performances and unspecified mechanisms regarding electric current production. Herein, carbon quantum dots (CQDs) were used to construct a nano-biohybrid system with Shewanella oneidensis MR-1 (S. oneidensis), through which the CQDs/S. oneidensis BioHEG achieved a maximum open-circuit voltage of ca. 0.65 V and short-circuit current density of ca. 5.23 mu A & sdot;cm-2. In addition, both the hydrovoltaic effect and electrical conductivity of CQDs/S. oneidensis nano-biohybrids were noticeably improved due to enhanced secretion of extracellular polymeric substances (EPS) and accelerated electron transfer upon CQDs implantation, thereby leading to a nearly 14-fold increase in output power density compared to the bare S. oneidensis cells. Studies aimed to elucidate the underlying mechanism indicated that the hybridization of CQDs and S. oneidensis greatly promoted the metabolic synthesis of outer membrane c-type cytochromes (OM c-Cyts) and the extracellular secretion of riboflavin (RF), which was demonstrated to be decisive in the current producing process of the CQDs/ S. oneidensis BioHEG. This work thus proposes a viable strategy to boost the hydrovoltaic electricity generation capacity of microbial biofilms and provides a new perspective on the mechanism of accelerated electron transfer pathways inside BioHEGs.

Abstract ：
Energy fluxes driven by predation are crucial to the relationships between biodiversity and ecosystem functioning in soils. However, there is little empirical evidence connecting these fluxes within soil micro-food webs to soil multifunctionality. Here, we initially used a long-term field experiment to investigate the extent to which nematode predation influences energy fluxes in soil micro-food webs and, in turn, impacts soil multifunctionality. Based on our analysis of body mass-scaled metabolic rates for 70 organismal groups, we estimated that nematodes require roughly three orders of magnitude more energy per individual than bacteria. In the field, we found nematode addition to increase multitrophic diversity and to strengthen interactions between bacteriafeeding nematodes and bacteria. This resulted in multitrophic energy fluxes that were 5.9-169.4 % greater than in soil lacking nematode additions. Specifically, nematode addition reinforced the bacterial energy channel, resulting in greater energy transfer from basal resources to bacteria and subsequently to protists and bacterivorous or omnivorous-predatory nematodes, which altered energy composition and reduced energy flow uniformity. Moreover, our results revealed that elevated multitrophic diversity and shifts in the energetic structure of soil micro-food webs mediated the enhancement in soil multifunctionality. Lastly, a complementary 13C-tracer microcosm experiment validated selective predation by nematodes on bacterial taxa (e.g., Mesorhizobium and Paenibacillus), as shown by significant positive correlations between 13C-labeled bacteria and 13C-enriched nematodes that explain the trophic transfer observed in nematode addition field treatments. Taken together, this study demonstrates that selective predation by nematodes reorganizes energy flow within soil micro-food webs, offering mechanistic evidence that predator-driven shifts in energy flow underpin biodiversity-function relationships in agricultural soils.

Abstract ：
The COVID-19 pandemic had a profound impact on the environment due to the extensive use of disinfectants to control the virus. While the dramatic increase in the use of disinfectants during the COVID-19 pandemic has been shown to affect antibiotic resistome in rivers, the impact on soils remains underexplored. Here, we collected 332 metagenomic farm soil samples across China before (2017-2019) and during (2020-2022) the COVID-19 pandemic and compared differences in antibiotic resistance genes (ARGs), mobile genetic elements (MGEs), and bacterial community characteristics. Our results revealed a significant increase in the abundance of ARGs and MGEs during the COVID-19 pandemic compared to the pre-pandemic period. Additionally, we observed a significant rise in the abundance of potentially pathogenic bacteria during the pandemic, including Pseudomonas, Salmonella, and Vibrio, while changes in human activities during the COVID-19 pandemic significantly impacted the composition of soil bacterial communities. Partial Least Squares Path Modeling indicated that the use of disinfectants increased the dissemination of ARGs by elevating the abundance of MGEs. Collectively, these findings suggest that the increased use of disinfectants to control the SARS-CoV-2 virus, likely contributed the spread of ARGs in soils during the COVID-19 pandemic. © 2024, The Authors.

Abstract ：
The transformation and stabilization of soil organic carbon (SOC) are important processes of global carbon (C) cycling, with implications for climate change. Much attention has been given to microbial anabolic processes driving SOC accrual. These are referred to as the soil microbial carbon pump (MCP), which emphasizes the contribution of microbial metabolism and necromass to the stable soil C pool. However, we still lack a fundamental understanding of how trophic interactions between soil fauna and microbiota modulate microbial necromass production and, consequently, SOC formation. Here, we provide an ecological perspective on the impacts of trophic interactions on modulating necromass formation and C accrual in soils. We discuss the mechanisms of trophic interactions in the context of food web ecology, with a focus on trophic control of microbial population densities and their influences on soil microbiota assembly. We foresee that integrating trophic interactions into the soil MCP framework can provide a more comprehensive basis for guiding future research efforts to elucidate the mechanisms modulating microbial necromass and SOC formation in terrestrial ecosystems. This perspective offers an ecological foundation for leveraging the use of biological interventions to enhance SOC accrual, providing valuable insights for sustainable C management strategies.

Abstract ：
Two facultatively aerobic strains, designated SGZ-02(T) and SGZ-792(T), were isolated from plant Pennisetum sp., exhibiting the highest 16S rRNA gene sequence similarities with the type strains of Sphingomonas zeae LMG 28739(T) (98.6%) and Massilia forsythiae NBRC 114511(T) (98.4%), respectively. SGZ-02(T) grew between 5 and 45 degrees C, pH 5.0-11.0 and tolerated NaCl concentrations of 0-4% (w/v), whereas SGZ-792(T) thrived at 5-40 degrees C, pH 5.0-11.0 and NaCl tolerance to 0-3.5% (w/v). The major quinone of SGZ-02(T) was ubiquinone-10, with the dominant fatty acids being C-16:0 (13.5%), Summed Feature 3 (6.3%), C-14:02-OH (5.3%) and Summed Feature 8 (66.3%). SGZ-792(T) predominantly contained ubiquinone-8, with major fatty acids being C-16:0 (20.3%), Summed Feature 3 (5.0%) and Summed Feature 8 (54.7%). Average nucleotide identity and digital DNA-DNA hybridization values between two strains and their closest references strains were below the bacterial species threshold. Based on genotypic and phenotypic characteristics, strains SGZ-02(T) and SGZ-792(T) are proposed as novel species within the genera Sphingomonas and Massilia, respectively. The suggested names for the new species are Sphingomonas fuzhouensis sp. nov. (SGZ-02(T) = GDMCC 1.4033(T) = JCM 36769(T)) and Massilia phyllosphaerae sp. nov. (SGZ-792(T) = GDMCC 1.4211(T) = JCM 36643(T)), respectively.

Abstract ：
Bio-hydrovoltaic systems, which leverage the energy embedded in water's natural processes, present a promising avenue for sustainable energy production. Despite notable advances in non-living hydrovoltaic systems, research into biological materials remains relatively underdeveloped, leaving their unique advantages and long-term reliability potential largely untapped. This Review presents a comprehensive synthesis of progress in the field, with a particular focus on the evolution from non-living to living hydrovoltaic systems, and a precise articulation of their conceptual boundaries. We underscore a shift from structure-oriented material engineering toward biofunction-enabled energy conversion-a transition that enables breakthroughs in power output, system durability and environmental adaptability. Through systematic comparisons of mechanisms, biomaterial sources, performance metrics and emerging application scenarios, we identify current bottlenecks and propose targeted strategies. In light of recent trends, living hydrovoltaic systems hold particular promise as a forward-looking direction, offering a transformative platform for future hydrovoltaic internet, intelligence and ecological integration at scale. This Review delineates the conceptual and material transition from non-living to living hydrovoltaic systems, establishing bio-hydrovoltaics as a frontier in sustainable energy conversion from water.

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 ：
Nitric acid (HNO3) as a vital chemical is widely used in energy and environmental fields. However, its conventional production relies on ammonia synthesis, resulting in high energy consumption and environmental concerns. Here, we report a simple, efficient, and green conversion of N2 to HNO3 by contact electrocatalysis (CEC) under ambient conditions. Utilizing the electrification of poly(tetrafluoroethylene) (PTFE) particles with water under ultrasound, we demonstrate how this interaction promotes the activation of N2. Our results showed that the average yield of HNO3 can reach 40.73 +/- 1.80 mu M h-1 in air gas atmosphere. We utilized electron spin resonance and the fluorescence spectrum to confirm the evolution of hydroxyl radicals (OH). High-resolution mass spectrometry combined with isotope experiments provides strong evidence that water-PTFE can produce a contact electric effect through ultrasonic treatment, directly oxidize water or reduce O2 to produce OH, and oxidize N2 to produce HNO3 under anaerobic or aerobic conditions. This work not only provides a green and efficient method for direct N2 fixation into HNO3 but also stimulates further exploration of CEC-driven chemical processes, particularly highlighting its potential for industrial application, and attempts to explain some of the N2 fixation phenomena in the environment.

Abstract ：
Biological nitrogen fixation (BNF) as the primarily nitrogen supply for rice growth has lately been linked to Fe(III) reduction in paddy field. Rice root iron plaque (IP) is crucial in rhizosphere elements cycling and retaining pollutants, but the synergistic interaction between rhizospheric Fe cycle and BNF remains elusive. Herein, rice seedlings with and without IP on rice root were cultured under hydroponic conditions to explore the extent and the underlying mechanism of IP influencing BNF using acetylene reduction assay and N-15 labeling DNA-based stable isotope probing (DNA-SIP) combined with metagenomics. IP on rice root surface exhibited a diurnal Fe(III)/Fe(II) redox rhythm. In the presence of IP, the nifH gene abundance and nitrogenase activity were significantly increased by 1.15 x 10(8)similar to 1.15 x 10(11) copies/g.dw and 134 similar to 566 mu mol C2H4/(L.h), which enhanced the N-15 abundance in rice shoot and root by 36.4% and 23.1% and further facilitated 2.13 and 1.87 times more biomass accumulation than that without IP. The BNF activity was significantly inhibited by dissociating IP or breaking diurnal Fe redox rhythm. DNA-SIP revealed the enrichment of diazotrophic Azotobacter, Burkholderia, Phytobacter and Dechlormonas by IP and metagenomic binning identified the presence of genes related to BNF and extracellular electron transfer in such diazotrophs, suggesting their genetic potential to mediate synergetic BNF and Fe(III) reduction.
