Query: NC_012029:1525929 Halorubrum lacusprofundi ATCC 49239 chromosome 1, complete genome

Lineage: Halorubrum lacusprofundi; Halorubrum; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea

General Information: Formerly Halobacterium lacusprofundi, this organism is an extremely halophilic archaeon isolated from Deep Lake, Antarctica. Extremely halophilic archaeon isolated from the Antarctic. Halorubrum lacusprofundi is a red pigmented halophilic archaeon which has been found in hypersaline marine enviornments. Originally thought to be a psychrophile, further research determined that the optimum temperature for growth for Halorubrum lacusprofundi was from 31 - 37 degrees C.

Subject: NC_000917:1778173 Archaeoglobus fulgidus DSM 4304, complete genome

Lineage: Archaeoglobus fulgidus; Archaeoglobus; Archaeoglobaceae; Archaeoglobales; Euryarchaeota; Archaea

General Information: This is the type strain (DSM 4304) of the Archaeoglobales, and was isolated from a geothermally heated sea floor at Vulcano Island, Italy. Doubling time is four hours under optimal conditions. The organism is an autotrophic or organotrophic sulfate/sulfite respirer. An additional distinguishing characteristic is blue-green fluorescence at 420 nm. This bacterium is the first sulfur-metabolizing organism to have its genome sequence determined. Growth by sulfate reduction is restricted to relatively few groups of prokaryotes; all but one of these are Eubacteria, the exception being the archaeal sulfate reducers in the Archaeoglobales. These organisms are unique in that they are only distantly related to other bacterial sulfate reducers, and because they can grow at extremely high temperatures. The known Archaeoglobales are strict anaerobes, most of which are hyperthermophilic marine sulfate reducers found in hydrothermal environments. High-temperature sulfate reduction by Archaeoglobus species contributes to deep subsurface oil-well 'souring' by iron sulfide, which causes corrosion of iron and steel in oil-and gas-processing systems.
