Berkelbacteria

Berkelbacteria is a bacterial phylum with candidate status, meaning there are no cultured representatives for this group. It is part of the Candidate [phyla radiation|Candidate Phyla Radiation].
Berkelbacteria was first reported in 2012, at which time it was classified as a divergent lineage of Parcubacteria and referred to as ACD58. It was proposed as a phylum in 2014. Representatives of this phylum have been detected in a variety of environments, including a deep thermokarst lake in the Sasapimakwananisikw River Valley, an acetate-amended alluvial aquifer adjacent to the Colorado River, and marine sediments from the Peru Margin seafloor.
