Emended descriptions of genera of the family Halobacteriaceae

Abstract

The family Halobacteriaceae currently contains 96 species whose names have been validly published, classified in 27 genera (as of September 2008). In recent years, many novel species have been added to the established genera but, in many cases, one or more properties of the novel species do not agree with the published descriptions of the genera. Authors have often failed to provide emended genus descriptions when necessary. Following discussions of the International Committee on Systematics of Prokaryotes Subcommittee on the Taxonomy of Halobacteriaceae, we here propose emended descriptions of the genera Halobacterium, Haloarcula, Halococcus, Haloferax, Halorubrum, Haloterrigena, Natrialba, Halobiforma and Natronorubrum. © 2009 IUMS.
