“…During all three operational cycles in both OCV and CCV modes, the values of the recorded voltage results maybe, attributed to the formation of the biofilm on the surface of the anode, furthermore the capacity for bacterial content to produce and transfer the electrons to the anode surface without chemical mediators. that the MFC performance was enhanced with the application of the optimal external resistance, these observations have found in accordance with the previous literature [34]. The pH value has a strong effect on MFC microbial activity which is reflected in the overall MFC performance [35].…”

This study investigated the bioelectrical performance of a single-chamber microbial fuel cell (SCMFC) fueled with acetate as the electron donor and inoculated with municipal solid waste rejected fractions (MSWRFs) as a microbial inoculum. The molecular characterization of the bacterial community structures of the anodic biofilm was conducted based on 16s RNA gene sequencing. The results indicated that the highest open-circuit voltage (OCV) was 797 mV and the system had a maximum power density of 134.5 mW/m2 at a stable current density of 328 mA/m2. The microbial fuel cell’s (MFC) columbic efficiency (CE) was 55% at a maximum substrate degradation rate of about 86.6% based on COD removal efficiency. The molecular analysis of the anodic bacterial isolates indicated that the phylogenetic bacterial mixture was dominated by seven strains with similarity percentage above 99% for each strain: Enterococcus faecalis, Clostridium butyricum, Bacillus sp., Bacillus subterranous, Enterobacter celoaca, Klebsiella pneumonia, and Escherichia coli. These results suggested that MSWRFs bacterial consortia have a moderate symbiotic structure as indicated by electrons release in parallel with substrate decomposition.

“…Dairy wastewater (3620mg COD/L) was investigated by Mansoorian et al (2016) in a two-chamber MFC and produced a maximum power density of 621 mW/m 2 , which is the highest power density reported among studies listed in Table 3. The Mansoorian et al (2016) study also reported >90% COD reduction and coulombic efficiency higher than 37%. Mohan et al (2010b) investigated using diluted dairy wastewater in a single-chamber MFC under different organic loadings.…”

“…The efficiency of the MFCs differs drastically depending on the type of wastewater, the operation conditions and the reactor setup (Logan et al, 2006; Gude, 2016). For instance, while the treatment of dairy wastewater resulted in a current density of 0.79 A/m 2 and a COD removal of more than 90% (Mansoorian et al, 2016), a MFC fed with paper wastewater produced only 125 mA/m 2 and only 78% of the organic carbon was consumed (Velasquez-Orta et al, 2011). Hence, the question arises whether or how bioelectrochemical systems could be adapted to the specific needs that result from the individual wastewater stream.…”

The aim of this study was the development of a specifically adapted microbial community for the removal of organic carbon from an industrial wastewater using a bioelectrochemical system. In a first step, ferric iron reducing microorganisms were isolated from the examined industrial wastewater. In a second step, it was tested to what extent these isolates or a cocultivation of the isolates with the exoelectrogenic model organism Geobacter sulfurreducens ( G. sulfurreducens ) were able to eliminate organic carbon from the wastewater. To establish a stable biofilm on the anode and to analyze the performance of the system, the experiments were conducted first under batch-mode conditions for 21 days. Since the removal of organic carbon was relatively low in the batch system, a similar experiment was conducted under continuous-mode conditions for 65 days, including a slow transition from synthetic medium to industrial wastewater as carbon and electron source and variations in the flow rate of the medium. The overall performance of the system was strongly increased in the continuous- compared to the batch-mode reactor and the highest average current density (1,368 mA/m 2 ) and Coulombic efficiency (54.9%) was measured in the continuous-mode reactor inoculated with the coculture consisting of the new isolates and G. sulfurreducens . The equivalently inoculated batch-mode system produced only 82-fold lower current densities, which were accompanied by 42-fold lower Coulombic efficiencies.
