Query: NC_010321:1361748 Thermoanaerobacter pseudethanolicus ATCC 33223 chromosome, complete
Lineage: Thermoanaerobacter pseudethanolicus; Thermoanaerobacter; Thermoanaerobacteraceae; Thermoanaerobacterales; Firmicutes; Bacteria
General Information: Thermoanaerobacter ethanolicus was isolated from a hot spring microbial mat in Yellowstone National Park. It is a thermophilic anaerobic bacterium, which ferments a wide range of hexose and pentose sugars, as well as starch and pullulan, to ethanol.
Subject: NC_010556:462500 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.
