In this study, the effect of salinity (5, 15, 25 and 35‰) on growth and total chlorophyll content of Nannochloropsis sp. BJ17 was evaluated. Moreover, chlorophyll content during logarithmic and stationary phases was investigated. The results showed that maximum cell growth and chlorophyll concentration of Nannochloropsis sp. BJ17 were achieved at the salinity of 15‰. The algae had the higher total chlorophyll concentration in stationary phase than in logarithmic phase. The authors conclude that, the optimum growth and chlorophyll content of Nannochloropsis sp. BJ17 were achieved in salinity of 15‰.
