The Thermoprotei is a class of the Thermoproteota.
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.
Ignicoccus is a genus of hyperthermophillic Archaea living in marine hydrothermal vents. They were discovered in samples taken at the Kolbeinsey Ridge north of Iceland, as well as at the East Pacific Rise in 2000.
The Desulfurococcales is an order of the Thermoprotei, part of the kingdom Archaea. The order encompasses some genera which are all thermophilic, autotrophs which utilise chemical energy, typically by reducing sulfur compounds using hydrogen. Desulfurococcales cells are either regular or irregular coccus in shape, with forms of either discs or dishes. These cells can be single, in pairs, in short chains, or in aciniform formation.
In taxonomy, the Methanococcales are an order of the Methanococci.
The Nitrosopumilales are an order of the Archaea class Nitrososphaeria.
In taxonomy, the Ferroplasmaceae are a family of the Thermoplasmatales.
Methanobacteriaceae are a family of archaeans in the order Methanobacteriales.
The Pyrodictiaceae are a family of disc-shaped anaerobic microorganisms belonging to the order Desulfurococcales, in the domain Archaea. Members of this family are distinguished from the other family (Desulfurococcaceae) in the order Desulfurococcales by having an optimal growth temperature above 100 °C, rather than below 100 °C.
In taxonomy, Acidianus is a genus of the Sulfolobaceae.
In taxonomy, Metallosphaera is a genus of the Sulfolobaceae.
Acidilobus is a genus of archaea in the family Acidilobaceae.
Halalkalicoccus is a genus of the Halobacteriaceae.
Halobiforma is a genus of halophilic archaea of the family Natrialbaceae.
In taxonomy, Natronococcus is a genus of the Natrialbaceae.
Natronorubrum is a genus in the family Halobacteriaceae.
The Nautiliaceae are a family of bacteria placed in an order to itself, Nautiliales. The members of the family are all thermophilic.
Planifilum is a Gram-positive and aerobic bacterial genus from the family of Thermoactinomycetaceae.
Marmoricola is a Gram-positive and chemoorganotrophic bacterial genus from the family of Nocardioidaceae.
Halorubraceae is a family of halophilic, chemoorganotrophic or heterotrophic archaea within the order Haloferacales. The type genus of this family is Halorubrum. Its biochemical characteristics are the same as the order Haloferacales.
