Many iron (Fe) redox processes that were previously assumed to be purely abiotic, such as
photochemical Fe reactions, are now known to also be microbially mediated. Owing to this …

Extracellular electron transfer (EET) is the physiological process that enables the reduction
or oxidation of molecules and minerals beyond the surface of a microbial cell. The first …

Electromicrobiology deals with the interactions between microorganisms and electronic
devices and with the novel electrical properties of microorganisms. A diversity of …

Bioelectrochemical systems (BESs) are unique systems capable of converting the chemical
energy of organic waste including low-strength wastewaters and lignocellulosic biomass …

Shewanella oneidensis strain MR-1 is widely studied for its ability to respire a diverse array
of soluble and insoluble electron acceptors. The ability to breathe insoluble substrates is …

Bacteria able to transfer electrons to metals are key agents in biogeochemical metal cycling,
subsurface bioremediation, and corrosion processes. More recently, these bacteria have …

Electroactive biofilms (EABFs) generated by electrochemically active microorganisms have
many potential applications in bioenergy and chemicals production. Biofilm electroactivity …

It is well established that some reduced fermentation products or microbially reduced
artificial mediators can abiotically react with electrodes to yield a small electrical current …

Microbial fuel cells (MFCs) are not yet commercialized but they show great promise as a
method of water treatment and as power sources for environmental sensors. The power …

The performance of a microbial fuel cell (MFC) depends on a complex system of parameters.
Apart from technical variables like the anode or fuel cell design, it is mainly the paths and …
