Methanobacteriati (formerly "Euryarchaeota", from Ancient Greek εὐρύς eurús, "broad, wide") is a kingdom of archaea. Methanobacteriati 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

==Description== The Methanobacteriati are diverse in appearance and metabolic properties. The kingdom contains organisms of a variety of shapes, including both rods and cocci. Methanobacteriati may appear either gram-positive or gram-negative depending on whether pseudomurein is present in the cell wall. Methanobacteriati also demonstrate diverse lifestyles, including methanogens, halophiles, sulfate-reducers, and extreme thermophiles in each. Others live in the ocean, suspended with plankton and bacteria. Although these marine Methanobacteriati are difficult to culture and study in a lab, genomic sequencing suggests that they are motile heterotrophs.
