The microbial fuel cell (MFC) has gained interest among the scientific community due to the feasibility of transforming organic wastes directly into electrical energy through biocatalysis or enzymatic bioelectrochemical reactions. In the present study, an effective coculture system, namely, Serratia marcescens AATB1 and Klebsiella pneumoniae AATB2, was used in the MFC system. The isolated strains, AATB1 and AATB2 were identified as biofilm producing bacteria. The experiments were performed in a two-chambered MFC setup with septic tank wastewater as the substrate in a 5 days batch mode. Pure culture of S. marcescens AATB1 and K. pneumoniae AATB2, and their cocultures were able to produce energy with the maximum current densities of 728.85 ± 36 mA/ m 2 , 642.19 ± 32 mA/m 2 and 869.11 ± 43 mA/m 2 , respectively, and the maximum power densities of 341.65 ± 17 mW/m 2 , 257.51 ± 12 mW/m 2 and 398.69 ± 19 mW/m 2 , respectively. During the process, cyclic voltammetry analysis has revealed the electrochemical behavior of the anodic biofilm. Approximately, 70.42% ± 3.52% of chemical oxygen demand removal was achieved during the process. Biofilm formation by the adhesion of microbes on the electrode surfaces was visualized by confocal laser scanning microscope and scanning electron microscope. All the three MFC systems were produced by biofilms containing extracellular polymeric substance from S. marcescens AATB1 (55 ± 2.75 μg/cm 2 of protein, 61 ± 3.05 μg/cm 2 of carbohydrate) and K. pneumoniae AATB2 (46 ± 2.30 μg/cm 2 of protein, 53 ± 2.65 μg/cm 2 of carbohydrate) and coculture (60 ± 3.00 μg/cm 2 of protein, 69 ± 3.45 μg/cm 2 of carbohydrate). Furthermore, the anode biofilm metabolites were identified by Gas Chromatography-Mass Spectrometry (GC-MS) and Nuclear Magnetic Resonance NMR spectroscopy.

“…MFC is a biological approach that not only raises power generation standards but also addresses fuel economy by the utilization of domestic and industrial wastewater. This system generates power along with wastewater treatment leading to a sustainable future that can use non-fossil resources for power generation [63]. In general, power is generated owing to the metabolism of bacteria that produce electrons by consuming the substrate present as contaminants in wastewater inside MFC and these electrons then complete the reaction by moving through an external circuit towards the cathode [64].…”

“…Therefore, technologies that combine both energy production and waste treatment could be considered very promising for practical application in the near future. In this context, microbial fuel cells (MFCs), which generate power through the decomposition of organic compounds contained in the various wastewaters/effluents, have gained considerable scientific interest in the last 10 years [2,3]. Electricity production in MFCs is due to the electrocatalytic activity of specific microbial consortia (exo-electrogens), which typically colonize in the anodic electrode and consume the organics, generating electrons [3][4][5].…”

In the present work, four different wastewaters from the food industry were used in parallel, in four identical dual-chamber MFCs, with graphite granules as anodic electrodes. Specifically, a mixture of hydrogenogenic reactor effluents (effluents from a dark fermentation reactor fed with cheese whey (CW), for hydrogen production), CW, and a mixture of expired fruit juices and wastewater from the confectionery industry were simultaneously used in MFCs to evaluate the effect of the type of effluent/wastewater on their efficiency. An electrochemical characterization was performed using electrochemical impedance spectroscopy measurements under open- (OCP) and closed-circuit conditions, at the beginning and end of the operating cycle, and the internal resistances were determined and compared. The results showed that the highest OCP value, as well as the highest power density (Pmax) and Coulombic efficiency (εcb) at the beginning of the operating cycle, was exhibited by the MFC, using a sugar-rich wastewater from the confectionery industry as substrate (sugar accounts for almost 92% of the organic content). This can be correlated with the low internal resistance extracted from the Nyquist plot at OCP. In contrast, the use of CW resulted in a lower performance in terms of OCP, εcb and Pmax, which could be correlated to the high internal resistance and the composition of CW, a substrate rich in lactose (disaccharide), and which also contains other substances (sugars account for almost 72% of its organic content, while the remaining 28% is made up of other soluble compounds).
