Haloarchaea

Haloarchaea (halophilic archaea, halophilic archaebacteria, halobacteria) are a class of archaea under the phylum Euryarchaeota, found in water saturated or nearly saturated with salt. 'Halobacteria' are now recognized as archaea rather than bacteria and are one of the largest groups of archaea. The name 'halobacteria' was assigned to this group of organisms before the existence of the domain Archaea was realized, and while valid according to taxonomic rules, should be updated. Halophilic archaea are generally referred to as haloarchaea to distinguish them from halophilic bacteria.

Haloarcula (common abbreviation Har.) is a genus of extreme halophilic Archaea in the class of Halobacteria.

Haloferax (common abbreviation: Hfx.) is a genus of halobacteria in the order Haloferacaceae.

Halococcus (common abbreviation: Hcc.), from Ancient Greek ἅλς (háls), meaning "salt", and κόκκος (kókkos), meaning "berry", is a genus of archaeans in the family Halococcaceae.

Halorubrum is a genus in the family Halorubraceae. Halorubrum species are usually halophilic and can be found in waters with high salt concentration such as the Dead Sea or Lake Zabuye.

Natronobacterium is a genus of archaeans in the family the Natrialbaceae. A member of the domain Archaea, it is both an extreme halophile and alkaliphile, thriving at an optimum saline concentration of 20% and optimum pH of 10.

species of archaea

Halopiger is a genus of archaeans in the family Natrialbaceae that have high tolerance to salinity.

Natrialba is a genus of archaeans in the family Natrialbaceae. The genus consists of many diverse species that can survive extreme environmental niches, especially they are capable to live in the waters saturated or nearly saturated with salt (halophiles). They have certain adaptations to live within their salty environments. For example, their cellular machinery is adapted to high salt concentrations by having charged amino acids on their surfaces, allowing the cell to keep its water molecules around these components. The osmotic pressure and these amino acids help to control the amount of sa
