Carbon and nitrogen sources are considering as the essential substances for microalgae growth. In this study the effects of sodium Nitrate (NaNO₃) and sodium bicarbonate (NaHCO₃) on the growth rate of N. oleoabundans microalgae in BBM culture medium were investigated. In this regards, different concentrations of NaNO₃  as 0, 0.5. 1.0, 2.5, 5 and 10 and NaHCO₃ as 0, 0.25, 0.5, 0.75, 1.0 and 1.25 in BBM during 21 days were tested. According to the results, by application of 10 mM NaNO₃ the highest number of microalgae as (84.66±0.577)× 10⁶ cells/mL was recorded and in case of nitrogen absence no increase in cell numbers was observed (p <0.05). However, by increasing of the concentration of NaNO₃, the lipid production was decreased which the highest amount of lipid was recorded as 1.32±0.27 gL^-1 without nitrogen addition (p <0.05).  In case of NaHCO₃, by addition of 1.25 gL^-1 sodium bicarbonate the highest cell number as (96±1.00)× 10⁶ cell/mL was recorded whereas in its absence the lowest number of (2.00±0.00)× 10⁶ cell/mL was obtained (p <0.05). Similarly, by addition of higher amounts of NaHCo₃, the lipid production was decreased as its highest amount as 0.3±0.144 gL^-1 was produced at level of 0.25 gL^-1 of NaHCO₃ (p <0.05). Considering the positive effects of NaHCO₃ on growth of N. oleoabundans on BBM, it is recommended to use it for mass production of this microalgae.
