Query: NC_010814:3332088 Geobacter lovleyi SZ, complete genome
Lineage: Geobacter lovleyi; Geobacter; Geobacteraceae; Desulfuromonadales; Proteobacteria; Bacteria
General Information: Su-Zi Creek sediment was collected near a suburban residential area with no reported contamination in June 2002 near Seoul, South Korea. This species was isolated from creek sediment based on its ability to derive energy from acetate oxidation coupled to tetrachloroethene (PCE)-to-cis-1,2-dichloroethene (cis-DCE) dechlorination.
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.
