Query: NC_002689:1507900 Thermoplasma volcanium GSS1, complete genome
Lineage: Thermoplasma volcanium; Thermoplasma; Thermoplasmataceae; Thermoplasmatales; Euryarchaeota; Archaea
General Information: This strain is the type strain for this species, and was isolated from a solfataric (volcanic area that gives off sulfuric gases) field. Thermophilic archaea. This organism is a thermophilic, acidophilic, archaea that was isolated from acidic hydrothermal vents on the shore of Aeolian Island of Vulcano, Italy. Growth of this facultative aerobe occurs at temperatures of 33-67°C with optimal at 60°C and pH of 1.0-4.0 (optimal 2.0).
Subject: NC_021182:1 Clostridium pasteurianum BC1, complete genome
Lineage: Clostridium pasteurianum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: Environment: Soil; Isolation: Coal-cleaning residues; Temp: Mesophile; Temp: 30C. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Known opportunistic toxin-producing pathogens in animals and humans. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. Clostridium pasteurianum was first isolated from soil by the Russian microbiologist Sergey Winogradsky. This organism is able to fix nitrogen and oxidize hydrogen into protons. The genes involved in nitrogen fixation and hydrogen oxidation have been extensively studied in this organism.
