Résumé: | At the limits of life, hyper-saline aquatic ecosystems; Chott and
Sebkha are a model of choice of extreme environments, housing a
halophilic microflora that had to adapt to these conditions. In Algeria, these
ecosystems are poorly studied. However, our study was carried out on the
waters of Chott Tinsilt and Sebkha El Malah. The study of this microflora
revealed the presence of a significant morphological, physiological and
metabolic diversity. The molecular study allowed us to access to a
phylogenetic affiliation including an Archean Species (ATS1) and 7
bacterial species (A1, A2, A3, A4, B1, B4, B5). The results showed that
these isolates were related to the genera Haloferax (for the strain ATS1)
and Halomonas (strains A1, A2 and A4), Staphylococcus (strain A3),
Salinivibrio (strain B1), Planococcus (strain B4) and Halobacillus (strain
B5). Most isolates produced hydrolases at high salt concentrations. The
Production yields obtained are very promising for applications in the
biotechnology and industrial microbiology. |
