Long-distance electron transport in multicellular freshwater cable bacteria [PDF]
eLife, 2023 Filamentous multicellular cable bacteria perform centimeter-scale electron transport in a process that couples oxidation of an electron donor (sulfide) in deeper sediment to the reduction of an electron acceptor (oxygen or nitrate) near the surface ...

Long-distance electron transport occurs globally in marine sediments [PDF]
Biogeosciences, 2017 Recently, long filamentous bacteria have been reported conducting electrons over centimetre distances in marine sediments. These so-called cable bacteria perform an electrogenic form of sulfur oxidation, whereby long-distance electron transport links ...

Long-distance electron transport in individual, living cable bacteria [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Cable bacteria are centimeter-long, multicellular filamentous bacteria, which are globally occurring in marine and freshwater sediments. Their presence coincides with the occurrence of electrical fields, and gradients of oxygen and sulfide that are best explained by electron transport from sulfide to oxygen along the ...

Single molecule tracking of bacterial cell surface cytochromes reveals dynamics that impact long-distance electron transport. [PDF]
Proc Natl Acad Sci U S A, 2022 Abstract Using a series of multiheme cytochromes, the metal-reducing bacterium Shewanella oneidensis MR-1 can perform extracellular electron transfer (EET) to respire redox-active surfaces, including minerals and electrodes outside the cell.

Mineral formation induced by cable bacteria performing long-distance electron transport in marine sediments [PDF]
Biogeosciences, 2019 Cable bacteria are multicellular, filamentous microorganisms that are capable of transporting electrons over centimeter-scale distances. Although recently discovered, these bacteria appear to be widely present in the seafloor, and when active they exert ...

Long-distance electron transport by cable bacteria in mangrove sediments [PDF]
Marine Ecology - Progress Series, 2016 Cable bacteria are long, filamentoussulphur-oxidizing bacteria that induce long-distanceelectron transport in aquatic sediments. They turnthe seafloor into an electro-active environment, characterizedby currents and electrical fields, and whenpresent, they exert a strong impact on the geochemicalcycling in the seafloor. However, cable bacteriahave only

The geochemical fingerprint of microbial long-distance electron transport in the seafloor [PDF]
Geochimica Et Cosmochimica Acta, 2015 AbstractRecently, a novel “electrogenic” type of sulfur oxidation has been documented in marine sediments, whereby long filamentous cable bacteria are generating electrical currents over centimeter-scale distances. Here we propose a numerical model description that is capable of quantitatively simulating the solute depth profiles and biogeochemical ...
