Natural hot environments can represent an important source of microbial biodiversity and biomolecules with great added value. In this work, we compare the diversity of prokaryotic communities in Debagh and Ouled Ali, two terrestrial hot springs located in the province of Guelma (Algeria) using high-through-put sequencing methods. Environmental DNA...

Omniprésent dans notre vie quotidienne, l’aluminium (Al) est l’un des éléments traces métalliques les plus dangereux pour la santé humaine. Nous y sommes exposés quotidiennement, par l’alimentation, l’application d’antitranspirants, l’utilisation d’antiacides, la vaccination, etc. L’exposition est donc inévitable, et chaque jour des taux modérés de...

Halophilic archaea represent a promising natural source of carotenoids. However, little information is available about these archaeal metabolites and their biological effects. In the present work, carotenoids of strains Haloferax sp. ME16, Halogeometricum sp. ME3 and Haloarcula sp. BT9, isolated from Algerian salt lakes, were produced, extracted an...

A set of 110 extremely halophilic archaeal strains were isolated from seven distinct saline habitats located in different regions of Algeria. The physicochemical characterization of the samples showed that these habitats were thalassohaline. The carotenoid production from isolated strains varied from 0.1 to 3.68 µg/ml. Based on their physiological...
