The Crenarchaeota is one of the most abundant archaeal phyla in terrestrial environments, with a mean relative abundance of 0.5% of total prokaryotic phyla detected in terrestrial soils. They are widespread across soil samples with an occupancy of around 88%.

The Thermoproteota are prokaryotes that have been classified as a phylum of the domain Archaea. [2][3][4] Initially, the Thermoproteota were thought to be sulfur-dependent extremophiles but recent studies have identified characteristic Thermoproteota environmental rRNA indicating the organisms may be the most abundant archaea in the marine envir...

Recently, the first genome sequence of a mesophilic crenarchaeota, Cenarchaeum symbiosum, was completed. This mesophilic 'crenarchaeon' was included in archaeal phylogenies that are based on the...

Nov 26, 2021 · Crenarchaeota comprises both hyperthermophilic and cold-dwelling prokaryotes. The hyperthermophilic species of Crenarchaeota tend to cluster closely together and occupy short branches on the 16S rRNA gene phylogenetic tree.

May 3, 2012 · The archaeal phylum Crenarchaeota was originally considered to comprise extremophiles. Cultivated strains were thermophilic or hyperthermophilic organisms utilizing sulfur for energy metabolism...

Jan 3, 2020 · Crenarchaeota are primarily found in extreme environments, either hot ones or cold ones. Little is known about the cold-adapted species, except that they live in considerable numbers – 104 per ml. They are found in the Antarctic and probably the Arctic as well.

The Crenarchaeota are archaea that have been classified as a phylum of the Archaea domain.
