Elastic Deformation of Cellulose/Lignin‐Based Anode for Rejuvenating Aged Mix‐Cultured Electroactive Biofilms

Advanced Science, Год журнала: 2025, Номер unknown

Опубликована: Май 8, 2025

Abstract Electroactive biofilms (EABs) are essential components of both natural and artificial bio‐electrochemical systems (BESs). However, the inevitable decay EABs during prolonged operation can diminish their performance. In this contribution, an effective noninvasive strategy for rejuvenating aging by elastic deformation anode material is approved. The synthesized wood tracheid‐like structures showed excellent compressibility fatigue resistance in a wet state. findings indicate that after anode, aged biofilm exhibited 37.5% increase metabolic activity, multi‐SIM images confirmed removal dead cells. Analysis extruded substance revealed significant loosely bound extracellular polymeric which doesn't contribute directly to electron transfer. Community analysis demonstrated rejuvenation process suppressed ecological competition from non‐exoelectrogens. Overall, there notable 25.97% power density following anode. Additionally, ion diffusion, specific capacitance, catalytic response current all improved. To knowledge, first report employing restore decayed mix‐cultured electroactive biofilm, vital practical long‐term application BESs. This work also offers new insights into mechanical influence materials on microorganisms.

Hierarchically Porous Structure Based on Humic Acid Endogenous Modified Carbon Electrodes for Mes Energy Recovery and Electroactive Biofilm Conditioning

Опубликована: Янв. 1, 2024

The microbial electrochemical system (MES) holds promise for in synchronously wastewater treatment and resource utilization, yet it is hampered by suboptimal electron transfer efficiency between the electrode exoelectrogen. Generating highly active biofilms facilitating efficient exchange at anode-bacteria interface are critical MES enhancement. Customization of components structure can be achieved through endogenous modification carbonizing precursor. Herein, we introduced oxygen-containing groups heteroatoms into carbon skeleton doping with humic acid during fabrication phenolic-based electrodes. This process was refined combining controlled pore generation techniques using an anionic agent sacrificial templates, establishing a dual-channel optimization strategy component structural regulation. Consequently, resulting sodium acid-modified porous electrodes (SHEs) exhibited wettability (48 ± 1.5°) enhanced redox activity owing to their rich oxygenic functional groups. hierarchical architecture roughened surface texture SHEs contributed notable capacitance (1280 mF g–1) biocompatibility. Specifically, SHEPS samples highest energy density 4200 48 mW m–2 fostered biofilm Geobacter content 78%. synergistic interaction exoelectrogens non-exoelectrogens bolstered performance stability biofilm. study introduces novel approach synchronous regulation structure, guiding design high-performance applications. These promote development electrochemically capture, propelling towards practical implementation.
