Query: NC_002689:78297 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_010001:3473425 Clostridium phytofermentans ISDg, complete genome
Lineage: Lachnoclostridium phytofermentans; Lachnoclostridium; Lachnospiraceae; Clostridiales; Firmicutes; Bacteria
General Information: Isolated from forest soil near the Quabbin Reservoir in Massachusetts, USA. This organism plays an important industrial and ecological role in the anaerobic fermentation of cellulose and produces economically significant levels of acetate and ethanol. 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.
