Extracellular electron transfer genes expressed by candidate flocking bacteria in cable bacteria sediment [PDF]

mSystems
Cable bacteria, filamentous sulfide oxidizers that live in sulfidic sediments, are at times associated with large flocks of swimming bacteria. It has been proposed that these flocks of bacteria transport electrons extracellularly to cable bacteria via an

Multidisciplinary methodologies used in the study of cable bacteria. [PDF]

FEMS Microbiol Rev
Abstract Cable bacteria are a unique type of filamentous microorganism that can grow up to centimetres long and are capable of long-distance electron transport over their entire lengths. Due to their unique metabolism and conductive capacities, the study of cable bacteria has required technical innovations, both in adapting existing ...

Groundwater cable bacteria conserve energy by sulfur disproportionation. [PDF]

ISME J, 2020
Abstract Cable bacteria of the family Desulfobulbaceae couple spatially separated sulfur oxidation and oxygen or nitrate reduction by long-distance electron transfer, which can constitute the dominant sulfur oxidation process in shallow sediments.

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

Oxygen consumption of individual cable bacteria. [PDF]

Sci Adv, 2021
Oxygen reduction in a cable bacterium is condensed in a few terminal cells, while the rest of the filament lives oxygen free.

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 ...

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

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.

Cable Bacteria Get Energy Through Electrical Teamwork [PDF]

Frontiers for Young Minds, 2023
Cable bacteria are very different from most other bacteria. First of all, they are multicellular, and each cable bacterium has tens of thousands of cells connected in a chain called a filament that can be several centimeters long. What makes cable bacteria really special is the way they get the energy they need for living: the cells within a filament ...

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 ...
