“…Capital costs for biological wastewater treatment processes are 5-20 times less compared to advanced oxidation methods and the running costs are 3-10 times less. In order to reduce cost of treatment, the simultaneous degradation of dye wastewater and generation of electricity using MFCs has achieved considerable attention as an economical and environmentally friendly technique [2][3][4][5][6]. MFCs are bio-electrochemical devices that use microbes as catalysts to produce electricity by oxidizing organic and inorganic compounds in biomass.…”

Methyl red, a synthetic azo dye, was reported for not only being mutagenic but also its persistence has severe consequences on human health, such as cancer, alongside detrimental environmental effects. In the present study, the Pseudomonas putida OsEnB_HZB_G20 strain was isolated from the soil sample to study the catalytic activity for the degradation of methyl red dye. Another isolated strain, the Pseudomonas aeruginosa PA 1_NCHU strain was used as an electroactive anodophile and mixed with the Pseudomonas putida OsEnB_HZB_G20 strain to see the effect of co-culturing on the power generation in single-chambered microbial fuel cells (MFCs). The Pseudomonas putida OsEnB_HZB_G20 and Pseudomonas aeruginosa PA 1_NCHU strains were used as co-culture inoculum in a 1:1 ratio in MFCs. This work uses isolated bacterial strains in a co-culture to treat wastewater with varying methyl red dye concentrations and anolyte pH to investigate its effect on power output in MFCs. This co-culture produced up to 7.3 W/m3 of power density with a 250 mgL−1 of dye concentration, along with 95% decolorization, indicating that the symbiotic relationship between these bacteria resulted in improved MFC performance simultaneous to dye degradation. Furthermore, the co-culture of Pseudomonas putida and Pseudomonas aeruginosa in a 1:1 ratio demonstrated improved power generation in MFCs at an optimized pH of 7.

“…The most important features of the electrode are good biocompatibility, conduction, chemical stability, and e cient electron transfer between the bacterial and the electrode surface. A Membrane is a physical separator between the anolyte and catholyte, transferring developed protons in the anode to the cathode (Murali et al 2013).…”

In microbial fuel cells (MFC), oxidation and reduction processes occur simultaneously. In this study, the operating conditions affecting oxidation-reduction and electricity generation of MFC were optimized using the Taguchi Experimental Design model. Optimization was carried out for maximum power density, coulombic efficiency, azo dye removal and COD removal. With the determined optimum conditions (cathode pH of 3.0, cathode oxygen status of anaerobic, anode substrate of pre-treated, external resistance of 100 Ω, cathode electrode type of plain carbon, cathode electrode surface of 22 cm2, cathode conductivity of 20 µs/cm), 177.031 mW/m2 power density, 7.50% coulombic efficiency, 91.266% azo dye removal efficiency and 21.612% COD removal efficiency were obtained. From the Pareto analysis, it was determined that the power density, coulombic efficiency and COD removal efficiency were most affected by the substrate type at the anode, and the azo dye removal was most affected by the catholyte pH. With the polarization curve, it has been determined that the maximum power density is 145.11 mW/m2 and the internal resistance of the optimum MFC system is 243.3 Ω. The cyclic voltammogram performed with the optimum experiment was associated with oxidation and reduction reactions.
