The excessive consumption of fossil fuels causes massive emission of CO2, leading to
climate deterioration and environmental pollution. The development of substitutes and …

Electroactive bacteria produce or consume electrical current by moving electrons to and
from extracellular acceptors and donors. This specialized process, known as extracellular …

Redox cycling of extracellular electron shuttles can enable the metabolic activity of
subpopulations within multicellular bacterial biofilms that lack direct access to electron …

Microbial fuel cells (MFCs) are recognized as a future technology with a unique ability to
exploit metabolic activities of living microorganisms for simultaneous conversion of chemical …

Bioelectronic materials interface biomolecules, cells, organs, or organisms with electronic
devices, and they represent an active and growing field of materials research. Protein and …

Proteins achieve efficient energy storage and conversion through electron transfer along a
series of redox cofactors. Multiheme cytochromes are notable examples. These proteins …

Biology leverages a range of electrical phenomena to extract and store energy, control
molecular reactions and enable multicellular communication. Microbes, in particular, have …

The reduction of ferric iron (Fe (III)) to ferrous iron (Fe (II)) by dissimilatory iron-reducing
bacteria is widespread in anaerobic environments. The oxidation of Fe (II) in aerobic …

Multiheme cytochromes, located on the bacterial cell surface, function as long-distance (> 10
nm) electron conduits linking intracellular reactions to external surfaces. This extracellular …

The riboflavin-mediated indirect electron transfer process during EH40 steel corrosion was
investigated in Methanococcus maripaludis medium. The results showed that exogenous …
