In this study, fed-batch fermentation of Haloferax mediterranei using glucose and yeast extract as carbon and nitrogen source, respectively, was carried out to produce poly(hydroxyalkanoate) (PHA). After fermentation for 117 h, the concentration of H. mediterranei and PHA content reached 85.8 g/l and 48.6%, respectively.

Characterization of genes for chitin catabolism in Haloferax mediterranei
Applied Microbiology and Biotechnology, 2013Chitin is the second most abundant natural polysaccharide after cellulose. But degradation of chitin has never been reported in haloarchaea. In this study, we revealed that Haloferax mediterranei, a metabolically versatile haloarchaeon, could utilize colloidal or powdered chitin for growth and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV ...

α-Amylase activity from the halophilic archaeon Haloferax mediterranei
Extremophiles, 2003The halophilic archaeon Haloferax mediterranei is able to grow in a minimal medium containing ammonium acetate as a carbon and nitrogen source. When this medium is enriched with starch, alpha-amylase activity is excreted to the medium in low concentration. Here we report methods to concentrate and purify the enzyme.

Biopolymer Production by Haloferax Mediterranei
1991The halobacterium H. mediterranei is an organism of biotechnological potential due to its capacity as polymer producer. This microorganism accumulates poly-s-hydroxybutyrate as intracellular granules in very large amounts. PHB is an interesting biopolymer for its possible use as biodegradable thermoplastic.

Transcriptional profiles of Haloferax mediterranei based on nitrogen availability
Journal of Biotechnology, 2015The haloarchaeon Haloferax mediterranei is able to grow in the presence of different inorganic and organic nitrogen sources by means of the assimilatory pathway under aerobic conditions. In order to identify genes of potential importance in nitrogen metabolism and its regulation in the halophilic microorganism, we have analysed its global gene ...

Purification and biological characterization of halocin H1 from Haloferax mediterranei M2a
International Microbiology, 2002 The production of halocins, bacteriocin-like proteins of ecological significance, is a frequent characteristic of species from the family Halobacteriaceae. Halocin H1, produced by Haloferax mediterranei strain M2a, is a single 31-kDa polypeptide. Its purification was achieved by combining two chromatographic systems: Sepharose 4B linked to bacitracin ...

Glutamate synthase (GOGAT) is one of the two important enzymes involved in the ammonium assimilation pathway glutamine synthetase (GS)/GOGAT, which enables Hfx. mediterranei to thrive in media with low ammonium concentration or containing just nitrate as single nitrogen source.

Impact of haloazolisin production in the antiarchaeal activity of Haloferax mediterranei
2021Halobacteria, também conhecidas por haloarchaea, é uma classe de Archaea halófilas que habitam ambientes. À semelhança de todos os extremófilos, as haloarchaea desenvolveram mecanismos que lhes permitem sobreviver em condições de elevada salinidade, falta de nutrientes e exposição excessiva aos raios UV.
