Inactive "Ghost" Cells Do Not Affect Motility and Long-Range Electron Transport in Filamentous Cable Bacteria. [PDF]

Environ Microbiol
Cable bacteria are multicellular filamentous microorganisms that perform electrogenic sulphur oxidation over centimetre‐long distances. These filaments contain so‐called “ghost cells”, which display a highly reduced cytoplasmic content and a lack of ...

Cable Bacteria Skeletons as Catalytically Active Electrodes. [PDF]

Angewandte Chemie International Edition, 2023
Cable bacteria are multicellular, filamentous bacteria that use internal conductive fibers to transport electrons over centimeter distances from donors within anoxic sediment layers to oxygen at the surface.

Biogeochemical impacts of fish farming on coastal sediments: Insights into the functional role of cable bacteria [PDF]

Frontiers in Microbiology, 2022
Fish farming in sea cages is a growing component of the global food industry. A prominent ecosystem impact of this industry is the increase in the downward flux of organic matter, which stimulates anaerobic mineralization and sulfide production in ...

The genetic repertoire underlying electrogenic sulphur oxidation in cable bacteria [PDF]

BMC Genomics
Background Cable bacteria are filamentous, sulphur-oxidizing microorganisms of the Desulfobulbaceae family that conduct electrons over centimetre-scale distances, coupling sulphide oxidation in deeper sediments to oxygen reduction near the surface ...

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.

Evidence for cable bacteria inhabiting deep in anoxic sediment reveals a novel ecological niche [PDF]

Environmental Microbiome
Background Cable bacteria are filamentous sulphide-oxidisers capable of cm-scale electron transport. They are generally considered restricted to the upper few oxic–suboxic cm of marine sediments, where they couple sulphide oxidation to oxygen or nitrate ...
