The biocurrent generated by soil extracellular electron transfer (EET) partly drives biogeochemical cycles and controls quality. However, it is unclear how the abiotic biotic conditions affect conduction. In this study, response relationship of microenvironment in-situ was studied. results showed that red exhibited optimal efficiency, as evidenced maximum current density accumulated charge output, with increments 56–93 % 80–2800 %, respectively, compared other five types soils. Soil physicochemical properties were most important factor on generation, further quantity bioavailability dissolved organic matter, NH4+-N content, lower pH predictive indicators for exoelectrogenic processes addition, high likely determined a complex synergistic network transformation carbon nitrogen, electroactive bacteria involving functions cell wall/membrane cytochrome enzyme metabolism transport related EET process. Overall, we provide an insight into among conduction, properties, community metabolic function, support bioelectrochemical technology application.

The use of biochar and lime (CaO) is a common approach to mitigating soil acidification. However, little known about how amendments impact N2O emissions potential microbial mechanisms. We conducted 45-day microcosm incubation experiment examine emission associated functional guilds amendment in an acidic tea plantation soil. Results show that treatments significantly reduced cumulative by 49.69% 63.01%, respectively, while increasing CO2 27.51% 19.35%, respectively. Additionally, decreased the abundances bacterial nirK, nirS, nosZ fungal nirK genes, ammonia-oxidizing bacteria (AOB) complete (comammox) amoA genes. stimulated or inhibitory effects on genes were higher than lime. rate was positively linked with abundance gene but negatively correlated AOB comammox abundances. random forest linear regression analysis revealed denitrifiers most important predictors emissions. Lime alpha diversity altered community composition nirK-harboring denitrifiers. Ascomycota dominant belonging families Nectriaceae, Aspergillaceae, Chaetomiaceae, relative genera Chaetomium, Penicillium Fusarium Overall, our findings suggest more effective reducing emissions, this likely due powerful it has traits
