Two-chamber Microbial Fuel Cells (MFC) using graphite rods as electrodes were operated for simultaneous anaerobic sulfide and nitrate removal coupled with electricity generation. The MFC showed good ability to remove substrates. When the influent sulfide and nitrate concentrations were 780 mg/L and 135.49 mg/L, respectively, the removal percentages of sulfide and nitrate were higher than 90% an...

In this study, the simultaneous enzymatic decolorization of reactive blue 221 (RB221) and performance different electrode carbon nanotube (CNT)-modified/unmodified graphite cathodes were investigated in a dual-chamber Microbial Fuel Cell (MFC) at permanent temperature 25 °C. The maximum power density voltage increased by approximately 13.6% 50%, respectively, when using CNT-modified as cathode....

As world is going towards renewable energy sources, microbial fuel cell getting attention nowadays. In microbial fuel cell biomass is utilize and give energy (electricity), and also a good option for treatment for waste water. Fuel recovery from sewage sludge is a promising energy production method, which can simultaneously address energy issue and environmental concerns associated with waste t...

A miniature-microbial fuel cell (mini-MFC, chamber volume: 1.2 mL) was used to monitor biofilm development from a pure culture of Shewanella oneidensis DSP10 on graphite felt (GF) under minimal nutrient conditions. ESEM evidence of biofilm formation on GF is supported by substantial power density (per device cross-section) from the mini-MFC when using an acellular minimal media anolyte (1500 mW...

Oxygen-reducing biocathodes previously developed for microbial fuel cells (MFCs) have required energy-intensive aeration of the catholyte. To avoid the need for aeration, the ability of biocathodes to function with passive oxygen transfer was examined here using air cathode MFCs. Two-chamber, air cathode MFCs with biocathodes produced a maximum power density of 554 ± 0 mW/m(2), which was compar...

The study combined anaerobic composting of untreated rice straw with V-shaped microbial fuel cell (V-MFC) to investigate the hydrolysis of lignocellulose and electricity generation of V-MFC. Due to the configuration for V-MFC, protons that be generated by the process of lignocellulose degradation could be accumulated with composting liquid at the bottom of V-MFC, and increased the contact area ...

Air-exposed microbial fuel cells and screening techniques" (2010). Introduction: Internal resistance (R int) of microbial fuel cells (MFC) has been identified as a significant variable associated to cell power output and low values are desirable (Du et al., 2007). Therefore , the aim of this research was to evaluate the effect of inoculum type and architectural features of MFC (separation of el...

Highly saline solutions were examined as alternatives to chemical buffers in microbial fuel cells (MFCs). The performance of two-chamber MFCs with different concentrations of saline solutions in the cathode chamber was compared to those with a buffered catholyte (50mM PBS). The use of a NaCl catholyte improved the CE to 43-60% (28% with no membrane) due to a reduction in oxygen transfer into th...

Oxygen intrusion into the anode chamber through proton exchange membrane can result in positive redox conditions in fed-batch, two chamber MFCs at the end of a cycle when the substrate is depleted. A slight increase in dissolved oxygen to 0.3 mg/L during MFC operation was not found to adversely affect power generation over subsequent cycles if sufficient substrate (acetate) was provided. Purgin...

Power generation and wastewater treatment are two great challenges for sustainable development. Microbial fuel cells (MFCs) a alternative that can generate bioelectricity in the bioremediation process of wastewater. For this reason, objective research was to through double-chamber microbial-combustion cell systems from Covicorti Wastewater Treatment Plant (PTARC) anodic chamber electrogenic bac...
