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...

A microbial fuel cell (MFC) is a bioinspired energy converter which directly converts biomass into electricity through the catalytic activity of a specific species of bacteria. The effect of temperature on a miniaturized microbial fuel cell with Geobacter sulfurreducens dominated mixed inoculum is investigated in this paper for the first time. The miniaturized MFC warrants investigation due to ...

Microbial fuel cells (MFC) are a promising technology for sustainable production of alternative energy and waste treatment. A microbial fuel cell transformation chemical energy in the chemical bonds in organic compounds to electrical energy through catalytic reactions of microorganisms under anaerobic conditions. It has been known for many years that it is possible to generate electricity direc...

Today's global energy crisis requires a multifaceted solution. Bioenergy is an important part of the solution. The microbial fuel cell (MFC) technology stands out as an attractive potential technology in bioenergy. MFCs can convert energy stored in organic matter directly into bioelectricity. MFCs can also be operated in the electrolysis mode as microbial electrolysis cells to produce bioproduc...

PROJECT SUMMARY Bacteria capable of exocellular transfer of electrons to solid surfaces, called exoelectrogens, make it possible to obtain electricity from the breakdown of organic matter in microbial fuel cells (MFCs). We obtained several new exoelectrogenic bacteria during this project. We isolated Rhodopseudomonas palustris DX-1, and demonstrated for the first time that a pure culture could ...

Fast hexavalent chromium (Cr(VI)) determination is important for environmental risk and health-related considerations. We used a microbial fuel cell-based biosensor inoculated with a facultatively anaerobic, Cr(VI)-reducing, and exoelectrogenic Ochrobactrum anthropi YC152 to determine the Cr(VI) concentration in water. The results indicated that O. anthropi YC152 exhibited high adaptability to ...

Bio-electrical responses obtained from freshwater sediments by employing microbial fuel cell (MFC) technology were investigated in this experimental study. During the electricity generation, organic matter in the sediment was microbially oxidized under anaerobic conditions with an electrode serving as a terminal electron acceptor. It was found that the sediment organic matter (SOM) associated w...

Microbial fuel cell and microbial electrolysis cell are two major types of microbial electrochemical cells. In the present study, we governed modeling of these systems by concentrating on the simulation of bioelectrochemical reactions in both biofilm and anolyte and considering the effect of pH on the microbial growth. The simulation of microbial fuel and electrolysis cells can be described by ...

Microbial fuel cell (MFC) technology is promising for wastewater treatment because it enables recovery of clean electric energy as wastewater organic matter is oxidized. The preferred oxidant is the oxygen in air because it is cheap and readily available, but the efficiency of oxygen reduction is constrained by operating conditions (low oxygen solubility, temperature and mostly neutral pH). Con...
