Integrating biocatalysis with nanophotocatalysis provides a promising pathway to address the knotty environmental and energy problems. However, loss during transfer of extracellular electrons across nano-bio interface seriously limits efficiency whole-cell-based photobiocatalytic systems. Herein, we demonstrate an integrated multienergy codriven reaction platform containing BaTiO3 nanoparticles (BTO) for harvesting mechanical from flowing water elevate interfacial electric field, BiVO4 quantum dots (BQD) light generate photocarriers, Geobacter sulfurreducens (GS) accepting photoelectrons accomplish biocatalytic reactions. The synergism between piezoelectric photoelectric fields significantly promotes cross-membrane transport photoelectrons, contributing enhanced acetate metabolism, electron transfer, synthesis GS microbes. Such well-designed BQD/BTO-GS hybrids result in simultaneous degradation organic contaminants detoxification heavy metals approximately 100% treatment efficiency. rates tetracycline (TC) oxidation Cr(VI) reduction are determined be 32.8 9.58 times higher than that biocatalysis, respectively. Our exhibits exceptional apparent yield 15.54% at 400 nm, exceeding those most reported abiotic–biotic Further investigation verifies extensibility our strategy other enhancing efficiencies (such as methanogenesis, CO2 fixation, denitrification), thus offering inspiring applications. This work not only presents crucial insights into mechanism water-energy nexus but also paradigm construction sustainable systems via harnessing.

Abstract Bacterial biofilms are structured microbial communities that play a big role in diverse processes such as nutrient cycling and bacterial pathogenesis. Biofilms known for their electron transfer properties which essential metabolic processes, survival, maintaining redox balance. In this study, we investigated the electrogenic of Bacillus subtilis , producer electron-donating biofilms. Interdigitated gold electrodes were utilized to continuously measure electrochemical activity biofilm-forming B. cells well genetic mutants unable create them (biofilm-deficient), over three days growth. The formation extracellular polymeric substances (EPS) filamentous appendages was monitored via scanning microscopy (SEM). Chronoamperometry used assess activity, showed fluctuations electrical current at specific time points cells. contrast, biofilm-deficient no corresponding changes current. Cyclic voltammetry (CV) revealed significant differences between voltammograms hypothesized be result reduction secreted flavodoxin only Electrochemical impedance spectroscopy (EIS) also performed various intervals analyzed using an equivalent circuit model. We identified presence charge resistance (R ct ) exclusively correlated increased measured choronoamperometry. Finally, through confocal microscopy, found expression gene involved biofilm matrix formation, tasA with where measured. Altogether, these results indicate is primarily present rather than mutants. By combining microscopic methods, methodology developed monitor stages measurement substantiating correlation genes or activities. These data show activities within vary there temporal relationship responsible development.
