Query: NC_012632:1212780 Sulfolobus islandicus M.16.27 chromosome, complete genome

Lineage: Sulfolobus islandicus; Sulfolobus; Sulfolobaceae; Sulfolobales; Crenarchaeota; Archaea

General Information: This strain was isolated from a hot spring on the Kamchatka Penninsula, in the Russian Far East. Hyperthermophilic acidophilic sulfur-metabolizing archeon. Sulfolobus islandicus is a thermo-acidophilic archeae commonly identified in hot, acidic sulfur springs. This organism can grow both chemoautotrophically, using sulfur or hydrogen sulfide, and heterotrophically. S. islandicus can play host to a number of plasmids and viruses which may be useful in developing tools for genetic analysis. In addition, Sulfolobus islandicus isolates from different areas in Russia, Iceland, and the United States have been shown to be genetically distinct from each other making this organism useful for comparative analysis.

Subject: NC_010556:71776 Exiguobacterium sibiricum 255-15, complete genome

Lineage: Exiguobacterium sibiricum; Exiguobacterium; Bacillales Family XII; Bacillales; Firmicutes; Bacteria

General Information: This organism was isolated from a 2-3 million-year permafrost core in Siberia, Russia and can survive and grow rapidly at low temperatures. Analysis of long-term survival of psychrophilic organisms such as this one may aid understanding of the potential growth of organisms in astrobiology. Exiguobacterium sibiricum is a psychrotolerant organism able to grow at temperatures that range from -6 to 40 degrees C. This organism is also able to survive repeated freeze/thaw cycles which may contribute to its ability to survive in cold environments.
