Aquificaceae

Aquificaceae
Scientific classification
Domain:	Bacteria
Phylum:	Aquificota
Order:	Aquificales
Family:	Aquificaceae; Reysenbach 2002
Genera
	Aquifex; Hydrogenivirga; Hydrogenobacter; Thermocrinis;

The Aquificaceae family are bacteria that live in harsh environmental settings such as hot springs, sulfur pools, and hydrothermal vents. Although they are true bacteria as opposed to the other inhabitants of extreme environments, the Archaea, Aquificaceae genera are an early phylogenetic branch.^[1]
