Molecular identification of -carotene hyper producing strains of Dunaliella from saline environment using species specific Oligonucleotids Owing to its very high content of -carotene. The later is one of high demand molecules due to its benefits as nutritional, prophylactic, and therapeutic agent. It is a precursor of Vitamin A.
