Binataceae | Binatus soliTs | seqco.de/i:31410 |
| Genus Hadarchaeum | [Had.ar.chae'um] Gr. masc. n. Haidês, Hades, the underworld; N.L. neut. n. archaeum, archaeon; N.L. neut. n. Hadarchaeum, archaeon from the subsurface | Identical to the type species.

Hadarchaeaceae | Hadarchaeum yellowstonenseTs | seqco.de/i:31424 |
| Species Hydrothermarchaeum profundiTs | [pro.fun'di] L. gen. n. profundi, of/from the depth of the sea | The organism was formerly identified as JdFR-18 in the hydrothermal fluid from Juan de Fuca Ridge by Jungbluth et al. (2017) Sci. Data 4, 170037. doi: 10.1038/sdata.2017.37. An annotation of the genome is provided in the same original study. Metabolic capabilities inferred from the genome reveal a thermophilic carboxydotroph capable of chemotaxis and motility. The organism appears to capable of anaerobic respiration with sulfate serving as a terminal electron acceptor.

| Species Hydrothermus pacificusTs | [pa.ci'fi.cus] L. masc. adj. pacificus, peaceful, pertaining to Pacific Ocean | This is one of the first genomic representatives of the EM3 lineage, later known as Candidate bacterial phylum Hydrothermae as proposed by Jungbluth et al. (2017). The MAG of this species has been reconstructed from the deep subsurface biosphere - the Juan de Fuca Ridge subseafloor.

| Species Binatus soliTs | [so'li] L. gen. n. soli, of soil, referring to the isolation source of the organism | This species is the first genomic representative of candidate bacterial phylum UBP10. The MAG of this species was originally reconstructed from a soil metagenome by Parks et al. (2017).

| Species Hadarchaeum yellowstonenseTs | [yel.low.ston.en'se] N.L. neut. adj. yellowstonense, pertaining to the Yellowstone National Park, the place of sampling from where organism was found | A detailed metabolic description of the proposed Ca. H. yellowstonense, formerly identified as YNP_45, is given in the original work by Baker et al. (2016) Nat. Microbiol. 1, 16002. doi: 10.1038/NMICROBIOL.2016.2. The organisms was found in hot spring in Yellowstone National Park, USA.
The reduced genome size and previously inferred gene content (821) suggests that the genome has undergone streamlining. The inferred metabolic capabilities indicates oxidation of carbon monoxide, which may be coupled to H2O or nitrite reduction to ammonia. Also inferred to contain a variety of central carbon metabolic (C1 pathway) genes found in methanogens, which may be used for carbon fixation. The organism is inferred to be thermophilic. |
