OPTIMIZATION OF OPEN CULTIVATION CONDITIONS FOR THE ARAL STRAIN OF MICROALGA DUNALIELLA SALINA TO OBTAIN CAROTENOID-RICH BIOMASS
This study investigates the potential for cultivating the Aral Sea strain of microalgae Dunaliella salina in open-air conditions under
the climate of Uzbekistan to obtain carotenoid-rich biomass. The experiments were conducted in open troughs (ponds) 10 cm deep
with mixing and air bubbling in a quasi-continuous mode. It has been demonstrated that varying environmental factors - salinity,
light intensity, and temperature - enables effective management of mixed culture growth and enhances the biosynthetic activity of
cells. The obtained results showcase the potential of utilizing the extreme climatic conditions of the Aral Sea region for industrial
cultivation of Dunaliella salina for the biotechnological production of carotenoids and biomass applicable in the pharmaceutical
and food industries.
