Abstract: The study was conducted to evaluate the growth performance and proximate compositions of Chlorella sp. cultured in different NaNO3 concentrations. Chlorella sp. cultured at 8 g/L nitrogen concentration of NaNO3 had significantly (p < 0.05) higher growth performance concerning the cell density (6.33 × 106 cells m/L ) and optical density (0.461) compared to those culture at 12 g/L, 16 g/L, 20 g/L, and 24 g/L N, respectively. Additionally, significantly (p < 0.05) higher protein content (31.90% dry weight) had seen at 8 g/L N concentration compared to all other culture at different concentrations of NaNO3. Furthermore, significantly (p < 0.05) higher carbohydrate content (20.07% dry weight) and lipid content (23.47% dry weight) were observed in Chlorella sp. cultured at 8 g/L N concentration in comparison to those grown on other concentrations of NaNO3. Increasing and decreasing the nitrogen concentrations below or above 8 g/L N had a remarkable effect on the growth performance and biochemical composition of Chlorella sp.
