Electrogenic sulfur oxidation mediated by cable bacteria and its ecological effects [PDF]

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

Electrogenic Sulfur Oxidation by Cable Bacteria in Bivalve Reef Sediments [PDF]

Frontiers in Marine Science, 2017
Cable bacteria induce long-distance electron transport in the seafloor and can exert a powerful control on the elemental cycling in marine sediments by creating extreme excursions in porewater pH. Yet, the natural distribution of cable bacteria is still largely unknown, and so their role in coastal biogeochemical cycling remains poorly quantified. Here

Impact of electrogenic sulfur oxidation on trace metal cycling in a coastal sediment [PDF]

Chemical Geology, 2017
Electrogenic sulfur oxidation (e-SOx) is a newly discovered pathway of microbial sulfide oxidation, mediated by so-called cable bacteria. The reduction of oxygen near the sediment-water interface is coupled by long-distance electron transport to the oxidation of sulfide in deeper sediment, and in this way, electrical currents are induced within the ...

Cable Bacteria Activity Modulates Arsenic Release From Sediments in a Seasonally Hypoxic Marine Basin [PDF]

Frontiers in Microbiology, 2022
Eutrophication and global change are increasing the occurrence of seasonal hypoxia (bottom-water oxygen concentration <63 μM) in coastal systems worldwide.

The impact of electrogenic sulfur oxidation on the biogeochemistry of coastal sediments: A field study

Geochimica Et Cosmochimica Acta, 2016
Electro-active sediments distinguish themselves from other sedimentary environments by the presence of microbially induced electrical currents in the surface layer of the sediment. The electron transport is generated by metabolic activity of long filamentous cable bacteria, in a process referred to as electrogenic sulfur oxidation (e-SOx).

Electrogenic sulfur oxidation by cable bacteria in two seasonally hypoxic coastal systems [PDF]

Estuarine, Coastal and Shelf Science
Abstract: Cable bacteria can reach high densities in coastal sediments, and as a result of their unusual electrogenic lifestyle and intense metabolic activity, exert a major and distinct impact on biogeochemical cycling, both locally in sediments and at the ecosystem level.

Using Oxidative Electrodes to Enrich Novel Members in the Desulfobulbaceae Family from Intertidal Sediments

Microorganisms, 2021
Members in the family of Desulfobulbaceae may be influential in various anaerobic microbial communities, including those in anoxic aquatic sediments and water columns, and within wastewater treatment facilities and bioelectrochemical systems (BESs) such ...

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 ...

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

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 ...

Quantification of Cable Bacteria in Marine Sediments via qPCR

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
