In this present study, the effect of salinity and photoperiod on the growth of Nannochloropsis sp. and Tetraselmis sp. was examined to optimize microalgal growth. Different salinities (5, 10, 15 and 20‰) for Nannochloropsis sp. and (10, 15, 20 and 25‰) for Tetraselmis sp. were studied. Both microalgae were cultivated at two different photoperiod cycles (24:0 and 12:12 h light:dark). Maximum growth rates and cell concentrations for Nannochloropsis sp. and for Tetraselmis sp. were achieved at salinities of 10 and 15‰, respectively. In terms of photoperiod, the maximum growth rates and cell concentrations for both microalgae were obtained at photoperiod of 24:0 h light:dark. This study shows that the cell concentrations and growth rates of both microalgae are highly dependent on salinity and photoperiod.Keywords

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‰.Keywords
