Query: NC_009253:529494 Desulfotomaculum reducens MI-1 chromosome, complete genome
Lineage: Desulfotomaculum reducens; Desulfotomaculum; Peptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Uranium- and chromium-reducing sediment bacterium. Desulfotomaculum reducens is able to reduce uranium and chromium making it a potential agent for the bioremediation of heavy metals. This organism was isolated from heavy metal-contaminated marine sediment collected at the Mare Island Naval Shipyard on the San Francisco Bay, USA.
Subject: NC_010556:2773396 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.
