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_006370:768745 Photobacterium profundum SS9 chromosome 1, complete sequence
Lineage: Photobacterium profundum; Photobacterium; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria
General Information: Isolated at a depth of 2500 m from the Sulu Trough. High pressure tolerant bacterium. This bioluminescent genus was originally identified in 1878 in association with hake (a marine fish) in Cape Town, South Africa. This species was originally isolated from an amphipod homogenate enrichment from the Sulu Sea. It is a genetically tractable model system for studies of low temperature and high pressure adaptation, and has been used in studies of mono- and polyunsaturated fatty acid production under these conditions.
