Lineage: Wolinella succinogenes; Wolinella; Helicobacteraceae; Campylobacterales; Proteobacteria; Bacteria
General Information: Cow rumen bacterium. Wolinella succinogenes is most commonly isolated from the bovine rumen and is considered nonpathogenic, however, this organism has also been isolated from the human gingiva and dental root canal infections.
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.
