Query: NC_020419:782337 Uncultured Termite group 1 bacterium phylotype Rs-D17 DNA, complete
Lineage: uncultured Termite group 1 bacterium; enviromental sample; ; ; Elusimicrobia; Bacteria
General Information: The Termite Group 1 (TG1) bacteria are a dominant group in termite guts, where they are part of the symbiotic microbial community that is required for the termite to thrive. The TG1 bacteria are found as intracellular symbionts of various cellulolytic protists.
Subject: NC_010556:71776 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.
