Genera [1]
Hydrogenothermus Persephonella Sulfurihydrogenibium Venenivibrio

The Hydrogenothermaceae family are bacteria that live in harsh environmental settings. They have been found in hot springs, sulfur pools, and thermal ocean vents. They are true bacteria as opposed to the other inhabitants of extreme environments, the Archaea. An example occurrence of certain extremophiles in this family are organisms of the genus Sulfurihydrogenibium that are capable of surviving in extremely hot environments such as Hverigerdi, Iceland. ^[2]

Obtaining energy

Hydrogenothermaceae families consist of aerobic or microaerophilic bacteria, which generally obtain energy by oxidation of hydrogen or reduced sulfur compounds by molecular oxygen.

Phylogeny
