Query: NC_014013:301184 Sphingobium japonicum UT26S chromosome 2, complete genome
Lineage: Sphingobium japonicum; Sphingobium; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: Sphingobium japonicum (strain NBRC 101211 / UT26S) is a yellow-pigmented, non-motile, aerobic, hexachlorocyclohexane (HCH)-degrading Gram-negative bacterium isolated from a dumpsite in the vicinity of an industry that has been producing lindane. Sphingobium japonicum, formerly Sphingomonas paucimobilis, is able to degrade hexachlorocyclohexane which has been used extensively as insect control agents in the health and agriculture fields.
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.
