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.
