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_001263:243000 Deinococcus radiodurans R1 chromosome 1, complete sequence
Lineage: Deinococcus radiodurans; Deinococcus; Deinococcaceae; Deinococcales; Deinococcus-Thermus; Bacteria
General Information: This red-pigmented organism's name means "strange berry that withstands radiation", marking the fact that this organism is one of the most radiation-resistant known. It can tolerate radiation levels at 1000 times the levels that would kill a human and it was originally isolated in 1956 from a can of meat that had been irradiated with X-rays. The resistance to radiation may reflect its resistance to dessication, which also causes DNA damage. This organism may be of use in cleaning up toxic metals found at nuclear weapons production sites due to the radiation resistance. This bacterium is also a highly efficient transformer, and can readily take up exogenous DNA from the environment, which may also aid DNA repair. This organism carries multiple copies of many DNA repair genes, suggesting a robust system for dealing with DNA damage. The recombination system may rely on multiple copies of various repeat elements found throughout the genome.
