Methanolacinia Paynteri
In taxonomy, ''Methanolacinia'' is a genus of the Methanomicrobiaceae. The cells are bar-shaped and irregular 0.6 μm in diameter and 1.5–2.5 μm in length. They do not form endospores. Most are non-motile, but some have a single flagellum. They are strictly anaerobic. They produce methane through the reduction of carbon dioxide with hydrogen and cannot use formate, acetate or methyl compounds as substrates.

Archaea
Archaea ( ; singular archaeon ) is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences in environmental samples. Archaea and bacteria are generally similar in size and shape, although a few archaea have very different shapes, such as the flat, square cells of ''Haloquadratum walsbyi''. Despite this morphological similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes involved ...
