Desulfobulbaceae

The Desulfobulbaceae are a family of Thermodesulfobacteriota. They reduce sulphates to sulphides to obtain energy and are anaerobic.

The discovery of filamentous Desulfobulbaceae in 2012 elucidates the cause of the small electric currents measured in the top layer of marine sediment.<ref name="Pfeffer">Template:Cite journal</ref> The currents were first measured in 2010.<ref>Template:Cite journal</ref> These organisms, referred to as "cable bacteria", consist in thousands of cells arranged in filaments up to three centimeters in length. They transport electrons from the sediment that is rich in hydrogen sulfide up to the oxygen-rich sediment that is in contact with the water.<ref name="Pfeffer" /><ref>Template:Cite journal</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite news</ref><ref>Template:Cite journal</ref> Later investigations revealed their ability to use nitrate or nitrite as final electron acceptor in absence of oxygen<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref> Since the discovery, cable bacteria have been reported from a wide variety of sediments worldwide.<ref>Template:Cite journal</ref> Based on phylogenetic analysis of 16s rRNA and dsrAB genes it was proposed to allocate cable bacteria within two novel candidate genera i.e. Ca. Electrothrix and Ca. Electronema.<ref>Template:Cite journal</ref>
