Abditibacteriota is abacterial phylum[1] previously known asFBP candidatus, which is widespread in extreme environments onEarth, frompolar anddesertecosystems towastewater and contaminated mining sites. The first cultured representative came from Utsteinen in theSør Rondane Mountains (East Antarctica) and is achemoheterotrophic,gram-negative,aerobic andoligotrophic bacterium. It has a limited number ofcarbon sources, optimizedmetabolism for survival in low nutrient habitats. Extreme resistance against antibiotics and toxic compounds was identified. Phylogenetically, it would be related to the phylumArmatimonadota according to molecular analysis.[2]
