Cable bacteria with electric connection to oxygen attract flocks of diverse bacteria

Nature Communications, 2023
Cable bacteria are centimeter-long filamentous microbes that conduct electrons via internal wires, thus coupling sulfide oxidation between sediment layers. Here, Bjerg et al. show that the anoxic part of oxygen-respiring cable bacteria attracts swarms of

Quantification of Cable Bacteria in Marine Sediments via qPCR [PDF]

Frontiers in Microbiology, 2020
Cable bacteria (Deltaproteobacteria, Desulfobulbaceae) are long filamentous sulfur-oxidizing bacteria that generate long-distance electric currents running through the bacterial filaments. This way, they couple the oxidation of sulfide in deeper sediment

Indications for a genetic basis for big bacteria and description of the giant cable bacterium Candidatus Electrothrix gigas sp. nov.

Microbiology Spectrum, 2023
Bacterial cells can vary greatly in size, from a few hundred nanometers to hundreds of micrometers in diameter. Filamentous cable bacteria also display substantial size differences, with filament diameters ranging from 0.4 to 8 µm.

Electrogenic sulfur oxidation mediated by cable bacteria and its ecological effects

Environmental Science and Ecotechnology
At the sediment-water interfaces, filamentous cable bacteria transport electrons from sulfide oxidation along their filaments towards oxygen or nitrate as electron acceptors. These multicellular bacteria belonging to the family Desulfobulbaceae thus form

Emerging research on characterizing the potential of cable bacteria for CH4 mitigation

Ecological Indicators
Methane (CH4) contributes an essential portion for global warming as a pivotal greenhouse gas. Microorganisms are identified as an effective way to mediate and control CH4 emission.

Persistent flocks of diverse motile bacteria in long-term incubations of electron-conducting cable bacteria, Candidatus Electronema aureum

Frontiers in Microbiology, 2023
Cable bacteria are centimeters-long filamentous bacteria that oxidize sulfide in anoxic sediment layers and reduce oxygen at the oxic-anoxic interface, connecting these reactions via electron transport.

Biogeochemical impact of cable bacteria on coastal Black Sea sediment [PDF]

Biogeosciences, 2020
Cable bacteria can strongly alter sediment biogeochemistry. Here, we used laboratory incubations to determine the potential impact of their activity on the cycling of iron (Fe), phosphorus (P) and sulfur (S). Microsensor depth profiles of oxygen, sulfide

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 ...

The dynamics of cable bacteria colonization in surface sediments: a 2D view

Scientific Reports, 2021
Cable bacteria that are capable of transporting electrons on centimeter scales have been found in a variety of sediment types, where their activity can strongly influence diagenetic reactions and elemental cycling.
