ABSTRACTThermoproteales(phylumCrenarchaeota) populations are abundant in high-temperature (>70°C) environments of Yellowstone National Park (YNP) and are important in mediating the biogeochemical cycles of sulfur, arsenic, and carbon. The objectives of this study were to determine the specific physiological attributes of the isolatePyrobaculum yellowstonensisstrain WP30, which was obtained from an elemental sulfur sediment (Joseph's Coat Hot Spring [JCHS], 80°C, pH 6.1, 135 μM As) and relate this organism to geochemical processes occurringin situ. Strain WP30 is a chemoorganoheterotroph and requires elemental sulfur and/or arsenate as an electron acceptor. Growth in the presence of elemental sulfur and arsenate resulted in the formation of thioarsenates and polysulfides. The complete genome of this organism was sequenced (1.99 Mb, 58% G+C content), revealing numerous metabolic pathways for the degradation of carbohydrates, amino acids, and lipids. Multiple dimethyl sulfoxide-molybdopterin (DMSO-MPT) oxidoreductase genes, which are implicated in the reduction of sulfur and arsenic, were identified. Pathways for thede novosynthesis of nearly all required cofactors and metabolites were identified. The comparative genomics ofP. yellowstonensisand the assembled metagenome sequence from JCHS showed that this organism is highly related (∼95% average nucleotide sequence identity) toin situpopulations. The physiological attributes and metabolic capabilities ofP. yellowstonensisprovide an important foundation for developing an understanding of the distribution and function of these populations in YNP.

The genus Elioraea has only one species characterized microbiologically and two genomes sequenced. We have sequenced the genome of a unique Elioraea strain isolated from Yellowstone National Park and found it to be a distinct new species. Elioraea is suggested to be a member of the aerobic anoxygenic photosynthetic bacteria.
