Aerophobota
Deep-sea methane cycling bacteria
From Wikipedia, the free encyclopedia
Aerophobota is a candidate bacterial phylum within the domain Bacteria. This phylum is found mainly in deep-sea, hydrocarbon-rich sediments, especially those associated with methane hydrates. Aerophobota is notable for its likely involvement in organic carbon and methane cycling in anoxic, deep ocean sediment environments.[1]

Taxonomy
The classification is based on genomic and metagenomic data without cultured isolates, and the name is not yet validly published under formal bacterial nomenclature.[1][2][3]

Ecology and function
Aerophobetes are abundant in hydrate-containing, silty sediment layers beneath the ocean floor and thrive in anoxic (oxygen-free) conditions.[4] Genetic analyses suggest they ferment organic matter, producing hydrogen and acetate, which can then be used by syntrophic methanogenic archaea to generate methane.[5] These metabolic interactions indicate Aerophobota's likely contribution to methane formation and carbon cycling in deep-sea ecosystems.[6][7]
Environmental and biotechnological importance
Research into Aerophobota and its functional roles is of interest because methane is a potent greenhouse gas.[8] Understanding these microbes could inform strategies for mitigating methane emissions from seafloor hydrates.[9]
