title: Biotechnological applications and potentialities of halophilic microorganisms.
abstract: Halophilic microorganisms are found as normal inhabitants of highly saline environments and thus are considered extremophiles. They are mainly represented, but not exclusively, by the halobacteria (extremely halophilic aerobic Archaea), the moderate halophiles (Bacteria and some methanogens) and several eukaryotic algae. These extremophilic microorganisms are already used for some biotechnological processes, for example halobacteria are used for the production of bacteriorhodopsin, and the alga Dunaliella is used in the commercial production of β-carotene. Several other present or potential applications of halophiles are reviewed, including the production of polymers (polyhydroxyalcanoates and polysaccharides), enzymes, and compatible solutes, and the use of these extremophiles in enhanced oil recovery, cancer detection, drug screening and the biodegradation of residues and toxic compounds.
