Query: NC_009328:2161116 Geobacillus thermodenitrificans NG80-2 chromosome, complete genome

Lineage: Geobacillus thermodenitrificans; Geobacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria

General Information: Geobacillus thermodenitrificans NG80-2 was isolated from oil reservoir formation water taken at a depth of 2000 m and a temperature of 73 degrees C. This strain can use crude oil as a sole carbon source and can degrade 16 to 36 carbon alkanes. Geobacillus thermodenitrificans NG80-2 produces an emulsifier which may be useful for high temperature biodegradation or other industrial purposes. Members of this genus were originally classified as Bacillus. Recent rDNA analysis and DNA-DNA hybridization studies using spore-forming thermophilic subsurface isolates provided enough evidence to define the phylogenetically distinct, physiologically and morphologically consistent taxon Geobacillus. Geobacillus species are chemo-organotrophic, obligately thermophilic, motile, spore-forming, aerobic or facultatively anaerobic.

Subject: 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.
