Query: 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.
Subject: NC_008542:2631138 Burkholderia cenocepacia HI2424 chromosome 1, complete sequence
Lineage: Burkholderia cenocepacia; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This organism (HI2424; BCC1) was isolated as part of a study to find this organism in natural environments. Samples taken from fields that were planted with onions in New York in 1999 and 2000 were examined and it was discovered that isolates were the same as ones that can infect CF patients. This species (genomovar III) is part of the Burkholderia cepacia complex, which consists of 9 closely related species, also known as genomovars. These organisms are commonly found in soil and all are opportunistic pathogens espcially in cystic fibrosis patients.
