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.
In taxonomy, the Thermoplasmataceae are a family of the Thermoplasmatales. It contains only one genus, Thermoplasma. All species within Thermoplasmataceae are thermoacidophiles, and they grow at a temperature of 60 °C and pH 2. They were isolated from hydrothermal vents, fumaroles and similar environments.
In taxonomy, the Picrophilaceae are a family of microbes within Thermoplasmatales.
In taxonomy, the Methanococcales are an order of the Methanococci.
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.
Acidilobus is a genus of archaea in the family Acidilobaceae.
Halobiforma is a genus of halophilic archaea of the family Natrialbaceae.
Natronorubrum is a genus in the family Halobacteriaceae.
The Nautiliaceae are a family of bacteria placed in an order to itself, Nautiliales, or in the order Campylobacterales. The members of the family are all thermophilic.
Planifilum is a Gram-positive and aerobic bacterial genus from the family of Thermoactinomycetaceae.
Luteococcus is a bacterial genus from the family Propionibacteriaceae.
Marmoricola is a Gram-positive and chemoorganotrophic bacterial genus from the family of Nocardioidaceae.
Haloferacaceae is a family of halophilic, chemoorganotrophic or heterotrophic archaea within the order Haloferacales. The type genus of this family is Haloferax. Its biochemical characteristics are the same as the order Haloferacales.
Halarchaeum is a genus of halophilic archaea in the family of Halobacteriaceae.
Halorientalis is a genus of archaea in the family of Haloarculaceae.
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.
Planctomycetaceae is a family of bacteria. It is the only family in the order Planctomycetales.
Halostella is a genus of halophilic archaea in the family of Halobacteriaceae.
