Microbial Fuel Cells for Sulfide Removal
Environmental Science & Technology, 2006Thus far, microbial fuel cells (MFCs) have been used to convert carbon-based substrates to electricity. However, sulfur compounds are ubiquitously present in organic waste and wastewater. In this study, a MFC with a hexacyanoferrate cathodic electrolyte was used to convert dissolved sulfide to elemental sulfur.

Cathodes for microbial fuel cells
2016Increase in human activities across the globe has put forward several challenges for future generations, with uncontrolled energy demand near the top of the list. Relentless efforts are being made by researchers and policy makers to meet energy demands in renewable ways, which shows the possibility of several alternative energy systems.

Photosynthetic Microbial Fuel Cells
2016This chapter presents the current state of research on bioelectrochemical systems that include phototrophic organisms. First, we describe what is known of how phototrophs transfer electrons from internal metabolism to external substrates. This includes efforts to understand both the source of electrons and transfer pathways within cells.

Microbial fuel cells containingProteus vulgaris and oxidation-reduction (“redox”) mediators were investigated. The bacteria were chemically immobilized onto the surface of graphite felt electrodes, which supported production of continuous electric current and could be reused after storage A computer-controlled carbohydrate feed system enabled the cell ...

Microbial fuel cells (MFCs) are bioelectrochemical devices that produces electric power while treating wastewaters. These unique systems relies on the ability of certain electroactive bacteria to transfer their electrons extracellulary as a part of their metabolism when placed in proximity to a solid electrode.

Investigating Variability in Microbial Fuel Cells
Applied and Environmental Microbiology, 2023The research presented, although carried out in the area of microbial fuel cells, reaches an important and broadly impacting conclusion that when using mixed inoculate in replica reactors under replicated conditions, different communities emerge capable of different levels of metabolism.

Cellular life exists at the interface between electrochemical extremes. The energy of most living cells depends on the transfer of electrons from intracellular, electrically reduced biochemicals to oxidized extracellular acceptors. For almost one hundred years investigators have tried to tap into these processes in microbes for electrical power ...

Architectural adaptations of microbial fuel cells
Applied Microbiology and Biotechnology, 2018Conventional wastewater treatment consumes a large amount of money worldwide for removal of pollutants prior to its discharge into water body or facilitating reuse. Decreasing energy expenditure during wastewater treatment and rather recovering some value-added products while treating wastewater is an important goal for researchers.

Scaling up Microbial Fuel Cells
Environmental Science & Technology, 2008The goal of this study was to quantify the relation between the surface area of the current-limiting electrode of a microbial fuel cell (MFC) and the power density generated by the MFC. Shewanella oneidensis (MR-1) was grown anaerobically in the anodic compartment of an MFC utilizing lactate as the electron donor.
