General Information: Isolation: composting reactor; Temp: Thermophile; Temp: 50C. Thermobacillus composti (strain DSM 18247 / JCM 13945 / KWC4) is an aerobic, rod-shaped, spore-forming and moderately thermophilic Gram-negative bacterium isolated from a fed-batch composting reactor.
Subject: NC_010556:6612 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.
