Pyrolobus fumarii (Latin for "fire lobe of the chimney" [1]) is a species of archaea known for living and reproducing at extremely high temperatures that kill most organisms. [1] [2] P. fumarii is known as a hyperthermophile obligately chemolithoautotroph. In the simplest terms, this archaea grows best in warm temperatures ranging from 80 °C ...
Archaea were initially classified as bacteria, receiving the name archaebacteria (/ ˌ ɑːr k i b æ k ˈ t ɪər i ə /, in the Archaebacteria kingdom), but this term has fallen out of use. [5] Archaeal cells have unique properties separating them from Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla.
Euryarchaeota (from Ancient Greek εὐρύς eurús, "broad, wide") is a kingdom of archaea. [3] 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.

Halobacteriaceae is a family in the order Halobacteriales and the domain Archaea. [1] Halobacteriaceae represent a large part of halophilic Archaea, along with members in two other methanogenic families, Methanosarcinaceae and Methanocalculaceae. [2] The family consists of many diverse genera that can survive extreme environmental niches. [3]

The bacteria and archaea are thought to be the most ancient of lineages, [21] as fossil strata bearing the chemical signature of archaeal lipids have been dated back to 3.8 billion years ago. [22] The eukaryotes include all complex cells and almost all multicellular organisms. They are thought to have evolved between 1.6 and 2.1 billion years ...
Methanobacterium is a genus of the Methanobacteria class in the Archaea kingdom, which produce methane as a metabolic byproduct. [1] Despite the name, this genus belongs not to the bacterial domain but the archaeal domain (for instance, they lack peptidoglycan in their cell walls). [2]
