The dynamics of biomass accumulation and mineral nitrogen uptake by Dunaliella salina under batch cultivation conditions wereinvestigated. The culture exhibited a typical sigmoid growth pattern, comprising the lag, exponential, stationary, and decline phases.The maximum biomass concentration (1.10 g L⁻¹) was achieved on the fifth day of cultivation and was accompanied by intensivenitrogen consumption. By the eighth day, nitrogen in the culture medium was almost completely depleted, resulting in growthcessation and a subsequent decline in biomass to 0.30 g L⁻¹ by the end of the experiment. A pronounced inverse relationshipbetween nitrogen concentration and biomass accumulation was observed, confirming the limiting role of nitrogen in the growth ofD. salina. The results indicate that the optimal cultivation period for maximum biomass production is 5–7 days, whereas prolongedcultivation under nitrogen-deficient conditions may be applied to induce the biosynthesis of β-carotene and neutral lipids. Thesefindings provide a scientific basis for optimizing technological regimes for the industrial cultivation of D. salina.
