Thermoplasmata

In taxonomy, the Thermoplasmata are a class of the Euryarchaeota.[1]

Thermoplasmata
Scientific classification
Domain:	Archaea
Kingdom:	Euryarchaeota
Phylum:	Euryarchaeota
Class:	Thermoplasmata Reysenbach 2002
Order
Methanomassiliicoccales Iino et al. 2013 Methanomassiliicoccaceae Iino et al. 2013 Thermoplasmatales Reysenbach 2002 Thermogymnomonas Itoh et al. 2007 Ferroplasmaceae Golyshina et al. 2000 Picrophilaceae Schleper et al. 1996 Thermoplasmataceae Reysenbach 2002

All are acidophiles, growing optimally at pH below 2. Picrophilus is currently the most acidophilic of all known organisms growing at a minimum 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 Thermotoplasmata are thermophilic.

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[2] and National Center for Biotechnology Information (NCBI)[3] and the phylogeny is based on 16S rRNA-based LTP release 121 by 'The All-Species Living Tree' Project.[4]
