Efficient long-range conduction in cable bacteria through nickel protein wires [PDF]

Nature Communications, 2021
Filamentous cable bacteria conduct electrical currents over centimeter distances through fibers embedded in their cell envelope. Here, Boschker et al. show that the fibers consist of a conductive core containing nickel proteins that is surrounded by an ...

First single-strain enrichments of Electrothrix cable bacteria, description of E. aestuarii sp. nov. and E. rattekaaiensis sp. nov., and proposal of a cable bacteria taxonomy following the rules of the SeqCode

Systematic and Applied Microbiology
Cable bacteria are electrically conductive, filamentous Desulfobulbaceae, which are morphologically, functionally, and phylogenetically distinct from the other members of this family.

Cable Bacteria Get Energy Through Electrical Teamwork

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.

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.

Potential impacts of cable bacteria activity on hard-shelled benthic foraminifera: implications for their interpretation as bioindicators or paleoproxies [PDF]

Biogeosciences
Hard-shelled foraminifera are protists able to build a calcareous or agglutinated shell (called a “test”). Here we study the impact of sediment acidification on calcareous test preservation.

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.

Cable bacteria reduce methane emissions from rice-vegetated soils [PDF]

Nature Communications, 2020
Rice paddies are a major source of the Earth’s atmospheric methane, making these important food crops potent contributors to greenhouse gas emissions. Here the authors show that inoculation of paddies with a particular bacterium could significantly curb ...

Cable bacteria regulate sedimentary phosphorus release in freshwater sediments.

Water Research, 2023
Previous studies have demonstrated that e-SOx can regulate the sedimentary release of phosphorus (P) in brackish and marine sediments. When e-SOx is active, an iron (Fe) and manganese (Mn) oxide rich layer is formed near the sediment surface, which ...

Cable bacteria, living electrical conduits in the microbial world. [PDF]

Proc Natl Acad Sci U S A, 2019
Microorganisms spend their lives searching for chemical reactants that yield metabolically usable energy, one reactant providing electrons and the other accepting them in a redox reaction. In PNAS, Kjeldsen et al. (1) provide a comprehensive genomic and physiological analysis of bacteria that have evolved an ingenious solution to the persistent problem

Abundance and Biogeochemical Impact of Cable Bacteria in Baltic Sea Sediments. [PDF]

Environ Sci Technol, 2019
Oxygen depletion in coastal waters may lead to release of toxic sulfide from sediments. Cable bacteria can limit sulfide release by promoting iron oxide formation in sediments. Currently, it is unknown how widespread this phenomenon is. Here, we assess the abundance, activity, and biogeochemical impact of cable bacteria at 12 Baltic Sea sites.
