Abstract:Cable bacteria are long, filamentous bacteria with a unique metabolism involving centimetre-scale electron transport. They are widespread in the sediment of seasonally hypoxic systems and their metabolic activity stimulates the dissolution of iron sulfides (FeS), releasing large quantities of ferrous iron (Fe
2+
) into the pore water. Upon contact with oxygen, Fe
2+
oxidation forms a layer of iron(oxyhydr)oxides (FeO
x
), which in its turn… Show more
