Query: NC_008314:1465643 Ralstonia eutropha H16 chromosome 2, complete sequence

Lineage: Cupriavidus necator; Cupriavidus; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria

General Information: This strain (ATCC 17699; H16), formerly Alcaligenes eutrophus was originally isolated from sludge. Cupriavidus necator also known as Ralstonia eutropha is a soil bacterium with diverse metabolic abilities. Strains of this organism are resistant to high levels of copper or are able to degrade chloroaromatic compounds such as halobenzoates and nitrophenols making them useful for bioremediation. Other strains have been studied for their ability to produce polyhydroxybutyrates which have industrial application. Another strain is able to attack other bacteria and fungi when nutrients in the soil are low.

Subject: NC_010556:691498 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.
