Microbial community optimization for electricity generation in Microbial Fuel Cells
Microbial fuel cells (MFCs) are a type of fuel cells that use bacteria as biocatalyst to oxidize an organic substrate to release electrons, which can be harvested in an external circuit to produce electric energy. This technology hold the potential to help overcome energetic problems and at the same time treat waste water more efficiently than the current employed techniques. Despite all this p...
متن کاملComposition and role of the attached and planktonic microbial communities in mesophilic and thermophilic xylose-fed microbial fuel cells
A mesophilic (37 C) and a thermophilic (55 C) two-chamber microbial fuel cell (MFC) were studied and compared for their power production from xylose and the microbial communities involved. The anodeattached, membrane-attached, and planktonic microbial communities, and their respective active subpopulations, were determined by next generation sequencing (Illumina MiSeq), based on the presence an...
متن کاملComparative Metagenomic Analysis of Electrogenic Microbial Communities in Differentially Inoculated Swine Wastewater-Fed Microbial Fuel Cells
Bioelectrochemical systems such as microbial fuel cells (MFCs) are promising new technologies for efficient removal of organic compounds from industrial wastewaters, including that generated from swine farming. We inoculated two pairs of laboratory-scale MFCs with sludge granules from a beer wastewater-treating anaerobic digester (IGBS) or from sludge taken from the bottom of a tank receiving s...
متن کاملImpact of Ferrous Iron on Microbial Community of the Biofilm in Microbial Fuel Cells
The performance of microbial electrochemical cells depends upon microbial community structure and metabolic activity of the electrode biofilms. Iron as a signal affects biofilm development and enrichment of exoelectrogenic bacteria. In this study, the effect of ferrous iron on microbial communities of the electrode biofilms in microbial fuel cells (MFCs) was investigated. Voltage production sho...
متن کاملMicrobial Fuel Cells
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...
