Query: NC_011138:3182807 Alteromonas macleodii 'Deep ecotype', complete genome
Lineage: Alteromonas macleodii; Alteromonas; Alteromonadaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: Alteromonas macleodii 'Deep ecotype' was isolated from seawater obtained at a depth of 3500 meters from the Urania Basin in the Mediterranean Sea by plating. Alteromonas macleodii is an obligate marine bacterium isolated from both surface and deep seawater and often associated with particulate matter.
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.
