Query: NC_009073:1708544 Pyrobaculum calidifontis JCM 11548, complete genome
Lineage: Pyrobaculum calidifontis; Pyrobaculum; Thermoproteaceae; Thermoproteales; Crenarchaeota; Archaea
General Information: This organism is a facultatively anaerobic, hyperthermophilic archaeon, first isolated from a hot spring in the Philippines. Pyrobaculum calidifontis cannot use sulfur compounds for anaerobic growth and is only able to grow anaerobically using nitrate as an electron acceptor.
Subject: 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.
