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_011420:365505 Rhodospirillum centenum SW, complete genome
Lineage: Rhodospirillum centenum; Rhodospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Rhodospirillum centenum, also called Rhodocista centenaria, is a nitrogen-fixing photoheterotroph with a complex life cycle. R. centenum is one of the few known thermotolerant purple bacteria species with optimal growth temperature of 44 dgrees C and a maximal growth temperature of 48 degrees C. In liquid media this organism is motile by a single polar flagellum. R. centenum produces lateral flagella to become a swarming cell. Under low nutrient conditions R. centenum forms a desiccation- and UV-resistant cyst. R. centenum can often be cultivated from hot springs such as those found at Yellowstone National Park. R. centenum is emerging as a model organism for genetic and molecular genetic analysis of cyst formation.
