Microbial Extracellular Electron Exchange With Minerals And Other Microbes Lovley D R Youtube Microorganisms with electron transfer capabilities, such as metal reducing microorganisms, use specialized systems to exchange electrons between minerals and cells. in this review, shiet al. Nature communications (2023) the discovery of direct interspecies electron transfer (diet) and cable bacteria has demonstrated that microbial cells can exchange electrons over long distances (μm.
Molecular Mechanisms Of Microbial Extracellular Electron Transfer The Importance Of Multiheme Microbes that can transfer electrons to extracellular electron acceptors, such as fe (iii) oxides, are important in organic matter degradation and nutrient cycling in soils and sediments1,2. Microbial nanowires are electrically conductive extracellular appendages with nanometer diameters that transport electrons over micrometer distances. the term was first used to describe the 3 nm diameter type iv pili of geobacter sulfurreducens (figure 1 a), a microbe that excels at electron exchange with other microbial species, minerals, and. On the other hand, our group expected naturally occurring conductive iron oxide minerals (e.g., magnetite) to function as wires for electric syntrophy, based on the knowledge that some electricity generating bacteria have the ability to exchange electrons with conductive iron oxide minerals (34, 38, 67). Electron transfer in the reverse direction, i.e. from electrodes to microbes, is the basis for microbial electrosynthesis, in which microorganisms reduce carbon dioxide to fuels and other useful organic compounds with solar energy in a form of artificial photosynthesis that is more efficient and avoids many of the environmental sustainability.
