Query: NC_019940:2236630 Thioflavicoccus mobilis 8321 chromosome, complete genome
Lineage: Thioflavicoccus mobilis; Thioflavicoccus; Chromatiaceae; Chromatiales; Proteobacteria; Bacteria
General Information: Country: USA; Environment: Marsh, Mat; Isolation: flat, laminated microbial mat. This organism is a marine bacterium which is an obligate phototrophic organism. Under anoxic conditions this organism uses hydrogen sulfide and sulfur as electron donors and accumulates sulfur globules inside the cell.
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.
