An octameric prokaryotic glutamine synthetase from the haloarchaeonHaloferax mediterranei [PDF]
FEMS Microbiology Letters, 2006 The glutamine synthetase (EC 6.3.1.2) from the haloarchaeon Haloferax mediterranei has been purified and characterized in order to understand the ammonium assimilation in haloarchaea. Based on sodium dodecyl sulfate polyacrylamide gel electrophoresis and gel-filtration chromatography, the enzyme consists of eight subunits of 51.7 kDa, suggesting that ...

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin
Biotechnology and Applied Biochemistry, Volume 73, Issue 2, Page 913-926, April 2026.ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Role of the denitrifying Haloarchaea in the treatment of nitrite-brines [PDF]
, 1970 Haloferax mediterranei is a denitrifying halophilic archaeon able to reduce nitrate and nitrite under oxic and anoxic conditions. In the presence of oxygen, nitrate and nitrite are used as nitrogen sources for growth.
