Caldisphaera is a genus of archaea in the family Caldisphaeraceae. [1]
Euryarchaeota is a kingdom of archaea. Euryarchaeota are highly diverse and include methanogens, which produce methane and are often found in intestines; halobacteria, which survive extreme concentrations of salt; and some extremely thermophilic aerobes and anaerobes, which generally live at temperatures between 41 and 122 °C. They are separated from the other archaeans based mainly on rRNA sequences and their unique DNA polymerase. The only validly published name for this group under the Prokaryotic Code is Methanobacteriati.
Chrysiogenaceae is a family of bacteria.
The Thermoprotei is a class of the Thermoproteota.
Rhodobacterales are an order of the Alphaproteobacteria.
In taxonomy, the Methanopyri are a class of the Euryarchaeota.
In taxonomy, the Thermoplasmata are a class of the Euryarchaeota.
Thermoplasmatales is an order of archaeans in the class Thermoplasmata. All are acidophiles, growing optimally at pH below 2. Picrophilus is currently the most acidophilic of all known organisms, being capable of growing at a pH of -0.06. Many of these organisms do not contain a cell wall, although this is not true in the case of Picrophilus. Most members of the Thermotoplasmata are thermophilic.
In taxonomy, the Thermococci are a class of microbes within the Euryarchaeota.
In the taxonomy of microorganisms, the Methanomicrobia are a class of the Euryarchaeota.
Methanococci is a class of methanogenic archaea in the phylum Euryarchaeota. They can be mesophilic, thermophilic or hyperthermophilic.
Acidilobales are an order of archaea in the class Thermoprotei.
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.
Caldisphaeraceae are a family of archaea in the order Acidilobales.
Desulfurococcaceae are a family of the disc-shaped anaerobic microorganisms belonging to the order Desulfurococcales, in the domain Archaea. Members of this family are distinguished from the other family (Pyrodictiaceae) in the order Desulfurococcales by having an optimal growth temperature below 100 °C, rather than above 100 °C, and by being more diverse. Several genera of the family have been identified.
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.
Methanocaldococcus formerly known as Methanococcus is a genus of coccoid methanogen archaea. They are all mesophiles, except the thermophilic M. thermolithotrophicus and the hyperthermophilic M. jannaschii. The latter was discovered at the base of a “white smoker” chimney at 21°N on the East Pacific Rise and it was the first archaean genome to be completely sequenced, revealing many novel and eukaryote-like elements.
In taxonomy, Rhodothalassium is a genus of the Rhodobacteraceae. Up to now there is only one species of this genus known.
In taxonomy, Jannaschia is a genus of the Rhodobacteraceae.
In taxonomy, Pannonibacter is a genus of the Hyphomicrobiales.
Haladaptatus is a genus of halophilic archaea in the family of Halobacteriaceae. The members of Haladaptatus thrive in environments with salt concentrations approaching saturation
