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_015709:1459838 Zymomonas mobilis subsp. pomaceae ATCC 29192 chromosome, complete
Lineage: Zymomonas mobilis; Zymomonas; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: Country: United Kingdom; Isolation: Sick cider; Temp: Mesophile. The natural habitat of this organism includes sugar-rich plant saps where the bacterium ferments sugar to ethanol. The high conversion of sugars to ethanol makes this organism useful in industrial production systems, particularly in production of bioethanol for fuel. A recombinant strain of this bacterium is utilized for the conversion of sugars, particularly xylose, which is not utilized by another common sugar-fermenting organism such as yeast, to ethanol. Since xylose is a common breakdown product of cellulose or a waste component of the agricultural industry, it is an attractive source for ethanol production. Zymomonas mobilis was chosen for this process as it is ethanol-tolerant (up to 120 grams of ethanol per litre) and productive (5-10% more ethanol than Saccharomyces). This bacterium ferments using the Enter-Doudoroff pathway, with the result that less carbon is used in cellular biomass production and more ends up as ethanol, another factor that favors this organism for ethanol production.
