MODEL REDUCTION OF THE CONSEQUENCES OF THE HIPERSALIN STRESS AT DUNALIELLA SALINA

Dunaliella salina is a well known object model of biotech research, and the latest publications allowed the following lines for the practical application of the obtained fundamental results: the carotene producing, complex preparations producing, biofuel producing. Dunaliela bioactive complex preparations include lipids containing valuable essential polienic fatty acids: alpha-linolenic, gamma-linolenic and docozahexaenoic, phosphatidyl inositol and phosphatidyl choline - essential phospholipids with multiple uses in the pharmaceutical industry. Fundamental researches of Dunaliella salina refer in particular to two main areas: Dunaliella species’ systematic and phylogeny and microalgae’s adaptation mechanisms to environment salinity changes. Salinity stress is one of the efficient factors for increase lipids quantity in biomass, but at the same time it decreases the microalgae’s productivity. The negative effects of hypersalin stress could be reduced by adding in nutritive medium the biometals in different form and quantity
