Query: NC_011146:482440 Geobacter bemidjiensis Bem, complete genome
Lineage: Geobacter bemidjiensis; Geobacter; Geobacteraceae; Desulfuromonadales; Proteobacteria; Bacteria
General Information: Geobacter bemidjiensis Bem (ATCC BAA-1014, DSM 16622) was isolated from subsurface sediments collected in Bemidji, Minnesota, USA. This organism, like other Geobacter species, is capable of oxidizing organic compounds and coupling that to reduction of metals.
Subject: NC_010556:26567 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.
