Query: NC_012029:11986 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_015707:1911431 Thermotoga thermarum DSM 5069 chromosome, complete genome
Lineage: Thermotoga thermarum; Thermotoga; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: Country: Djibouti; Isolation: Continental solfataric spring; Africa; Temp: Hyperthermophile; Temp: 80C. This organism, a member of the Thermotogales, has the characteristic morphology of one or more cells contained in a sheath-like envelope which extends beyond the cell wall. Preliminary sequencing of Thermotogales genomes has identified extensive horizontal gene transfer between these organisms and the Archaea. Thermotoga thermarum does not grow at high salt concentrations (>0.6% NaCL). This organism also produces heat stable enzymes such as endoxylanase, beta xylosidase and alpha arabinofuranosidase which may have commercial uses.
