Insight into the Pseudocapacitive Behavior of Electroactive Biofilms in Response to Dynamic-Controlled Electron Transfer and Metabolism Kinetics for Current Generation in Water Treatment

Environmental Science & Technology, Год журнала: 2023, Номер 57(48), С. 19891 - 19901

Electroactive biofilms (EBs) engage in complex electron transfer and storage processes involving intracellular extracellular mediators with temporary capabilities. Consequently, electroactive exhibit pseudocapacitive behaviors during substrate degradation processes. However, comprehensive systematic research this area has been lacking. This study demonstrated that the property was an intrinsic characteristic of EBs. represents dynamic-controlled is critical current generation, unlike noncapacitive responses. Nontransient charge discharge experiments revealed a correlation between capacitive accumulation generation Additionally, analysis suggested maximum power density (Pmax) changed kinetic constants COD degradation, pseudocapacitances EBs directly proportional to Pmax. The interaction networks key latent variables were evaluated through partial least-squares path modeling analysis. results indicated cytochrome c closely associated formation pseudocapacitance In conclusion, can be considered valuable indicator for assessing behavior Pseudocapacitive have potential efficiently regulate biological reactions serve as promising carbon-neutral renewable strategy energy storage. An in-depth understanding undoubtedly advance development concept future.

To date, dozens of pilot-scale microbial fuel cell (MFC) devices have been successfully developed worldwide for treating various types wastewater. The availability and configurations separators are determining factors the economic feasibility, efficiency, sustainability, operability these devices. Thus, concomitant advances between MFC deserve further clarification. analysis separator has shown that their evolution proceeds as follows: from ion-selective to ion-non-selective, nonpermeable permeable, abiotic biotic. Meanwhile, cost is decreasing increasing. Notably, novel MFCs configured with biotic superior those in terms wastewater treatment efficiency capital cost. Herein, a highly comprehensive review (>100 L) conducted, we conclude intensive stack liquid cathode configuration more advantageous when highest priority. use permeable ensures hydrodynamic continuity within simplifies reactor operation. In addition, systemic comparison conducted conventional decentralized processes. showed comparable cost, higher long-term stability, significant superiority carbon emission reduction. development greatly contributed usability MFCs, which will play an important role scenarios future.

Xeno-Fungusphere: Fungal-Enhanced Microbial Fuel Cells for Agricultural Remediation with a Focus on Medicinal Plants

Agronomy, Год журнала: 2025, Номер 15(6), С. 1392 - 1392

Опубликована: Июнь 5, 2025

The xeno-fungusphere, a novel microbial ecosystem formed by integrating exogenous fungi, indigenous soil microbiota, and electroactive microorganisms within fuel cells (MFCs), offers transformative approach for agricultural remediation medicinal plant conservation. By leveraging fungal enzymatic versatility (e.g., laccases, cytochrome P450s) conductive hyphae, this system achieves dual benefits. First, it enables efficient degradation of recalcitrant agrochemicals, such as haloxyfop-P, with removal efficiency 97.9% (vs. 72.4% fungi alone) 27.6% reduction in activation energy. This is driven bioelectric field (0.2–0.5 V/cm), which enhances activity accelerates electron transfer. Second, generates bioelectricity, up to 9.3 μW/cm2, demonstrating real-world applicability. In soils, xeno-fungusphere MFCs restore health stabilizing the pH, enriching dehydrogenase activity, promoting nutrient cycling, thereby mitigating agrochemical-induced inhibition secondary metabolite synthesis ginsenosides, taxol). Field trials show herbicide 60 days, outperforming conventional methods. Innovations, adaptive electrodes, engineered strains, phytoremediation-integrated systems, have been used address limitations. technology bridges sustainable agriculture bioenergy recovery, offering benefits detoxification enhanced crop quality. Future IoT-enabled monitoring circular economy integration promise scalable, precision-based applications global agroecological resilience.
