Species InformationThe Haloferax volcanii DS2 genome is 4.01 Million bp long and contains approximately 4209 predicted genes. The genome is complete and being publicly released by Jonathan Eisen before journal publication while genome annotation is in progress. H. volcanii is a chemoorganotroph requiring complex nutrient medium and 1.5-2.5 M NaCl for growth. Cultures will grow at 37C, but optimal growth is at 42C.
Taxonomy: Archaea; Euryarchaeota; Halobacteria; Halobacteriales; Halobacteriaceae; Haloferax.
The most recent genome sequence draft was released April 2007 by the Institute for Genomic Research, but there is no associated genome publication to date. Isolation: Arch Microbiol 104:207-14 (1975) Mullakhanbhai MF, Larsen H, "Halobacterium volcanii spec. nov., a Dead Sea halobacterium with a moderate salt requirement." Abstract: A halophilic bacterium was isolated from bottom sediment from the Dead Sea. The organism possessed the properties of the halobacteria, but differed from the known species in two important respects, 1) the cells were disc shaped and often cupped when grown under optimum conditions, 2) the optimum requirements for sodium chloride was in the range 1.7--2.5 molar which is about half of that generally reported for the halobacteria. The organism was assigned to the genus Halobacterium and...

CreditsThe Archaeal Genome Browsers at UCSC were developed by members of theLowe Lab (Kevin Schneider,Katherine Pollard, Andy Pohl, Todd Lowe) and Robert Baertsch, with significant support fromthe UCSC Human GenomeBrowser group.The Archaeal Browsers are run by a slightly modifiedversion of the UCSC Human GenomeBrowser system. All queries, bug reports, content corrections, suggested improvements,and new track data submissions should be sent to Todd Lowe (lowe@soe.ucsc.edu).If you use the browser in your published research, please cite ourpublication in the Nucleic Acids Research DatabaseIssue.
