Vulcanisaeta
In alpha taxonomy, taxonomy, ''Vulcanisaeta'' is a genus (biology), genus of the Thermoproteaceae. Description and significance ''Vulcanisaeta'' is an anaerobic, heterotrophic, hyperthermophilic archaeon that grows optimally at 85–90 °C and at pH 4.0–4.5. The organism is isolated from samples collected directly from solfataric fields or piped hot spring water in eastern Japan. Genome structure Several ''Vulcanisaeta'' genomes have been sequenced, see List of sequenced archaeal genomes. The G + C content of its DNA, which is between 44 and 46%, is predicted to be relatively lower than other members of the Thermoproteaceae genera. Cell structure and metabolism The cells of ''Vulcanisaeta'' are straight to slightly curved rods, which range from 0.4 to 0.6 µm in width. In some cases, the cells are branched or bear spherical bodies at the terminals. The archaeon utilizes maltose, starch, malate, yeast extract, peptone, beef extract, casamino acids and gelatin as ...

Pyrobaculum
''Pyrobaculum'' is a genus of the Thermoproteaceae. Description and significance As its Latin name ''Pyrobaculum'' (the "fire stick") suggests, the archaeon is rod-shaped and isolated from locations with high temperatures. It is Gram-negative and its cells are surrounded by an S-layer of protein subunits. ''P. aerophilum'' is a hyperthermophilic and metabolically versatile organism. Different from other hyperthermophiles, it can live in the presence of oxygen and grows efficiently in microaerobic conditions. ''Pyrobaculum yellowstonensis'' strain WP30 was obtained from an elemental sulfur sediment (Joseph's Coat Hot Spring CHS 80 °C, pH 6.1, 135 μM As) in Yellowstone National Park (YNP), USA and 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, ...

Thermoproteus
In taxonomy, ''Thermoproteus'' is a genus of the Thermoproteaceae. These prokaryotes are thermophilic sulphur-dependent organisms related to the genera '' Sulfolobus'', '' Pyrodictium'' and '' Desulfurococcus''. They are hydrogen-sulphur autotrophs An autotroph or primary producer is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide,Morris, J. et al. (2019). "Biology: How Life Works", ... and can grow at temperatures of up to 95 °C. Description and significance ''Thermoproteus'' is a genus of anaerobes that grow in the wild by autotrophic sulfur reduction. Like other hyperthermophiles, ''Thermoproteus'' represents a living example of some of Earth's earliest organisms, located at the base of the Archaea. Genome structure Genetic sequencing of ''Thermoproteus'' has revealed much about the organism's modes of metabolism. Total genome length is 1.84 Mbp, and the ...

They are the only organisms known to lack the SSB proteins, instead possessing the protein ThermoDBP that has displaced them. The rRNA genes of these organisms contain multiple introns, which can be homing endonuclease encoding genes, and their presence can impact the binding of "universal" 16S rRNA primers often used in environmental sequencing surveys.

List Of Prokaryotic Names With Standing In Nomenclature
List of Prokaryotic names with Standing in Nomenclature (LPSN) is an online database that maintains information on the naming and taxonomy of prokaryotes, following the taxonomy requirements and rulings of the International Code of Nomenclature of Prokaryotes The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P. H. A. Sneath, 2003. A short hist .... The database was curated from 1997 to June 2013 by Jean P. Euzéby. From July 2013 to January 2020, LPSN was curated by Aidan C. Parte. In February 2020, a new version of LPSN was published as a service of the Leibniz Institute DSMZ, thereby also integrating the Prokaryotic Nomenclature Up-to-date service.

Genome Taxonomy Database
The Genome Taxonomy Database (GTDB) is an online database that maintains information on a proposed nomenclature of prokaryotes, following a phylogenomic approach based on a set of conserved single-copy proteins. In addition to breaking up paraphyletic groups, this method also reassigns taxonomic ranks algorithmically, creating new names in both cases. Information for archaea was added in 2020, along with a species classification based on average nucleotide identity. Each update incorporates new genomes as well as human adjustments to the taxonomy. An open-source tool called GTDB-Tk is available to classify draft genomes into the GTDB hierarchy. The GTDB system, via GTDB-Tk, has been used to catalogue not-yet-named bacteria in the human gut microbiome and other metagenomic sources. The GTDB is incorporated into the ''Bergey's Manual of Systematics of Archaea and Bacteria'' in 2019 as its phylogenomic resource. See also * PhyloCode * National Center for Biotechnology Informa ...

Silva Comprehensive Ribosomal RNA Database
SILVA is a ribosomal RNA database established in collaboration between the Microbial Genomics Group at the Max Planck Institute for Marine Microbiology in Bremen, Germany, the Department of Microbiology at the Technical University Munich, and Ribocon. Release 117 of the database (January 2014) held more than 4,000,000 small subunit (SSU - 16S/18S) and 400,000 large subunit In structural biology, a protein subunit is a polypeptide chain or single protein molecule that assembles (or "''coassembles''") with others to form a protein complex. Large assemblies of proteins such as viruses often use a small number of ty ... (LSU - 23S/28S) sequences. Sequences are provided as files for the ARB software environment.

All-Species Living Tree Project
The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB, SILVA rRNA database project, and LPSN, with the aim of assembling a database of 16S rRNA sequences of all validly published species of ''Bacteria'' and ''Archaea''. At one stage, 23S sequences were also collected, but this has since stopped. Currently there are over 10,950 species in the aligned dataset and several more are being added either as new species are discovered or species that are not represented in the database are sequenced. Initially the latter group consisted of 7% of species. Similar (and more recent) projects include the Genomic Encyclopedia of Bacteria and Archaea (GEBA), which focused on whole genome sequencing of bacteria and archaea. Tree The tree was created by maximum likelihood analysis without bootstrap: consequently accuracy is traded off for size and many phylum level clades are not correctly resolved (such as the Firmicutes).
