Euryarchaeota is a phylum 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 Thermoprotei is a class of the Thermoproteota.
In taxonomy, the Methanopyri are a class of the Euryarchaeota.
Halobacteriales are an order of the Halobacteria, found in water saturated or nearly saturated with salt. They are also called halophiles, though this name is also used for other organisms which live in somewhat less concentrated salt water. They are common in most environments where large amounts of salt, moisture, and organic material are available. Large blooms appear reddish, from the pigment bacteriorhodopsin. This pigment is used to absorb light, which provides energy to create ATP. Halobacteria also possess a second pigment, halorhodopsin, which pumps in chloride ions in response to photons, creating a voltage gradient and assisting in the production of energy from light. The process is unrelated to other forms of photosynthesis involving electron transport; however, and halobacteria are incapable of fixing carbon from carbon dioxide.
In taxonomy, the Thermoplasmata are a class of the Euryarchaeota.
Methanobacteria is a class of archaeans in the kingdom Euryarchaeota. Several of the classes of the Euryarchaeota are methanogens and the Methanobacteria are one of these classes.
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.
In taxonomy, the Methanococcales are an order of the Methanococci.
Methanosarcinales is an order of archaeans in the class Methanomicrobia.
The Nitrosopumilales are an order of the Archaea class Nitrososphaeria.
In taxonomy, the Thermococcales are an order of microbes within the Thermococci. The species within the Thermococcales are used in laboratories as model organisms. All these species are strict anaerobes and can ferment sugars as sources of carbon, but they also need elemental sulfur.
The Cenarchaeaceae are a family of the Archaea order, the Cenarchaeales.
In taxonomy, the Methanosaetaceae are a family of microbes within the order Methanosarcinales. All species within this family use acetate as their sole source of energy.
In taxonomy, the Methanosarcinaceae are a family of the Methanosarcinales.
In taxonomy, Cenarchaeum is a genus of the Cenarchaeaceae. The marine archaean Cenarchaeum symbiosum lives within the sponge Axinella mexicana.
Cenarchaeum symbiosum is a species of Archaea in the genus Cenarchaeum, in the phylum Nitrososphaerota in the domain Archaea. C. symbiosum is psychrophilic and is found inhabiting marine sponges.
