The new Aral strain Dunaliella salina AR-1 has been isolated and its
development cycle has been studied. The appearance, structure and reproduction of green
microalgae Dunaliella salina is described. It is shown that its main type of reproduction is
reproduction through the formation of palmels. Maximum accumulation of biomass was
observed at the concentration of NaCL 2.5-3.0 M and pH= 6.5-7.0. The composition of β-
carotenes in the biomass of green and brown form of Dunaliella salina AR-1 has been
studied, as well as the effect of nitrogen and phosphorus salts content on this process.
