The Acidianus genus consists of acidothermophiles which grow optimally and slowly in the temperature range 65-95 degrees Celsius and pH 2-4. Acidianus species are hemolithoautotrophic and facultatively anaerobic and are generally versatile physiologically. Depending on the culturing conditions, they can either reduce elemental S to H(2)S, catalysed by a sulphur reductase and hydrogenase, or oxidise elemental S to H(2)SO(4) utilizing the sulphur oxygenase-reductase holoenzyme. Acidianus hospitalis W1 was the first Acidianus strain to be isolated carrying a conjugative plasmid pAH1 which is a member of the plasmid family predicted to generate an archaea-specific conjugative apparatus. These plasmids are also integrative elements and in an encaptured state have been implicated in facilitating chromosomal DNA conjugation for some Sulfolobus species. A. hospitalis is also viable host for the model Acidianus alpha lipothrixvirus AFV1, a filamentous virus carrying exceptional claw-like structures at its termini. The genome seems to have a relatively stable chromosome (adapted from PMID 21607549). Plasmid pAH1 was not submitted as part of this genome project, however another version of pAH1 is available in INSDC accession number EU881703, see PMID 19007417.
