“…It was found that the power density and current density were five times and seven times higher compared to that of the MFC using anaerobic POME sludge. In fact, the power density and current densities were also higher than previously-published results related to the production of electricity in MFC using P. aeruginosa (Jayapriya and Ramamurthy, 2012;Rabaey et al, 2005).…”

“…Complete removal of color at the end of the two cycles process was also achieved. In another study, an MFC running using P. aeruginosa MTCC 2474 for a period of 9 days consumed 77% of COD (Jayapriya and Ramamurthy, 2012). However, the substrate used in the anode was Modified King A broth which contains glucose and peptone as the carbon and nitrogen source respectively.…”

“…MFCs with P. aeruginosa using graphite block electrodes and MO generated a maximum power density of 4100 μW m −2 ; however the internal resistance of the MFC was 15.8 kΩ. A critical factor in the power density achieved in a MFC was the system's internal resistance, which was primarily a function of the electrode material . The high internal resistance of the graphite block suggested that introducing other ions might facilitate electron mobility.…”

A laboratory‐scale H‐shaped Pseudomonas catalyzed microbial fuel cell (MFC) was investigated for its performance in decolourizing synthetic wastewater containing azo dyes. The azo‐dyes investigated in this study were methyl orange (MO), congo red, reactive blue 172 (RB), reactive yellow 145, and reactive red 2. Among the azo dyes in anode chamber MO resulted in the highest power density (4100 μW m−2) with graphite electrodes and a decolourization efficiency of 94%. The azo bonds were cleaved in all the dyes tested, and their metabolites in the anolytes were characterized by UV‐visible spectral and HPLC analyses. To reduce the internal resistance of MFC and maximize the power density, different metal salt doped graphite epoxy composites) were tested. In the case of azo dyes MO and RB, the power output increased substantially (almost 1.2 fold) when using Mn2+—GECE compared to graphite block. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 1623–1628, 2016

SUMMARYExoelectrogens are catalytic microorganisms competent to shuttle electrons exogenously to the electrode surface without utilizing artificial mediators. Diverse microorganisms acting as exoelectrogens in the fluctuating ambience of microbial fuel cells (MFCs) propose unalike metabolic pathways and incompatible, specific proteins or genes for their inevitable performance toward bioelectricity generation. A pivotal mechanism known as quorum sensing allows bacterial population to communicate and regulates the expression of biofilm-related genes. Moreover, it has been found that setting the anode potential affects the metabolism of the exoelectrogens and hence the output of MFCs. Microscopic, spectrometry investigations and gene deletion studies have confirmed the expression of certain genes for outer-membrane multiheme cytochromes and conductive pili, and their potential roles in the exoelectrogenic activity. Further, cyclic voltammetry has suggested the role of multifarious redox-active compounds secreted by the exoelectrogens in direct electron transport mechanisms. Besides, it also explores the various mechanisms of exoelectrogens with genetic and molecular approaches, such as biofilm formation, microbial metabolism, bioelectrogenesis, and electron transfer mechanisms from inside the exoelectrogens to the electrodes and vice versa.
