Abstract

Algeria has high algal biodiversity, of great interest and is rarely exploited. Isolation of Dunaliella salina strain Seq Duna5.8S, from Oran Lake in Algeria, was carried out for this purpose.
Algae of the genus Dunaliella salina are usually used for feed, for nutritional reinforcement as a vitamin A precursor and for pharmaceuticals and fine chemicals.
The aim of this research was to identify the isolated strain by morphological and molecular taxonomy using, ARNr 5.8s, for further development in this field.In this study, we associate morphological and molecular analysis to characterize a strain Seq Duna5.8S isolated from Oran Lake. Samples of natural populations show the appearance of several green and red cells, mobile or not with different shapes in diverse stages of development, corresponding to the presence Dunaliella salina. Plus ARNr 5.8s analysis was to corroborate the identification and phylogenetic analyses, for clarification of the taxonomy of these microalgae.
