DPANN (Diapherotrites, Parvarchaeota, Aenigmarchaeota, Nanoarchaeota, Nanohaloarchaea) is a superphylum of Extremophile Archaea.[1]
It was proposed in 2013 by Rinke et al.[2]
DPANN is an acronym formed by the initials of the first five groups discovered, Diapherotrites, Parvarchaeota, Aenigmarchaeota, Nanoarchaeota and Nanohaloarchaeota.
The superphylum DPANN groups together different phyla with a variety of environmental distribution and metabolism, ranging from symbiotic and thermophilic forms such as Nanoarchaeota, acidophiles like Parvarchaeota and non-extremophiles like Aenigmarchaeota and Diapherotrites.
Classification
- Diapherotrites. Found by phylogenetic analysis of the genomes recovered from the groundwater filtration of a gold mine abandoned in the USA.[3][4]
- Parvarchaeota and Micrarchaeota. Discovered in 2006 in strongly acidic sewage from a US mine.[5][6][7] They are of very small size and provisionally called ARMAN (Archaeal Richmond Mine Acidophilic Nanoorganisms).
- Woesearchaeota and Pacearchaeota. They have been identified both in sediments and in surface waters of aquifers and lakes, abounding especially in saline conditions.[8][9]
- Aenigmarchaeota. Found in wastewater from mines and in sediments from hot springs.[10]
- Nanohaloarchaeota. Distributed in environments with high salinity.[11]
- Nanoarchaeota. They were the first discovered (in 2002) in a hydrothermal source next to the coast of Iceland. They live as symbionts of other archaea.[12][13][14]
