Rumen Inoculum Enhances Cathode Performance in Single-Chamber Air-Cathode Microbial Fuel Cells.

Bioprospecting for electrochemically active bacteria has included the search for new sources of inoculum for microbial fuel cells in the last decade. Inoculated with a rumen-fluid enrichment and wastewater, power densities and soluble chemical oxygen demand removal were greater than reactors inoculated only with wastewater, whereas reactors inoculated only with wastewater were inoculated only with wastewater. Pyrosequencing results showed no significant differences between the anodic community groups constructed from both inocula and Pyrosequencing, but there were increased relative abundances of Azoarcus and Victivallis species in the cathodic rumen enrichment.

Insight into the performance discrepancy of GAC and CAC as air-cathode materials in constructed wetland-microbial fuel cell system.

The performance discrepancy between using granular activated carbon and columnar activated carbon as air-cathode materials was demonstrated by the constructed wetland-microbial fuel cell. The GAC's increased electron transport and oxygen reduction reactions are due to the electrochemical properties and the electron transport system's active involvement.

Long-term evaluation of an air-cathode microbial fuel cell with an anion exchange membrane in a 226L wastewater treatment reactor.

Although the treatment of municipal wastewater with microbial fuel cells has been extensively studied, scaling the systems up for practical use is difficult. A 226 L sewage treatment plant was installed with 27 MFC units, and chemical oxygen demand removal and electricity generation were investigated in this report. In a chemostat reactor with a COD of 140-36 mg/L and a hydraulic retention time of 9-42 h per year, A/M 2, 0. 072-0. 51 W/m 3, and 1. 7-4. 6 Wh/m 3 delivered 0. 12-0. 30 A/m 3 with a maximum retention time of 9-42 h/m 3 (in a year). MFC's 24-hour operation before post-aeration has been found to reduce the energy required to meet the discharge standard by 70%, reducing the ability of MFC in long-HRT-treatments such as the oxidation ditch. Anode-specific surface area can increase the anode-specific surface area, which could increase air-AEM MFCs used for practical applications.
