A Halocin Promotes DNA Uptake in Haloferax mediterranei [PDF]
Frontiers in Microbiology, 2019 Halocins are antimicrobial peptides or proteins that are produced by halophilic archaea. Although their function in inhibiting the growth of closely related haloarchaeal strains is well known, other physiological functions of halocins have also been ...

Characterisation of chlorate reduction in the haloarchaeon Haloferax mediterranei [PDF]
Biochimica et Biophysica Acta (BBA) - General Subjects, 2015 Haloferax mediterranei is a denitrifying haloarchaeon using nitrate as a respiratory electron acceptor under anaerobic conditions in a reaction catalysed by pNarGH. Other ions such as bromate, perchlorate and chlorate can also be reduced.Hfx. mediterranei cells were grown anaerobically with nitrate as electron acceptor and chlorate reductase activity ...

Production of polyhydroxyalkanoates from hydrolysed rapeseed meal by Haloferax mediterranei
Bioresource Technology, 2023 Rapeseed meal (RSM) hydrolysate is a potential low-cost feedstock for the production of polyhydroxyalkanoates (PHAs) by the archaea, Haloferax mediterranei. Acidic and enzymatic hydrolysis were carried out to compare effectiveness. Enzymatic hydrolysis is more effective than acidic hydrolysis for fermentation substrate leading to increased PHA ...
