摘要：In this present study, the effect of salinity and photoperiod on the growth of Nannochloropsis sp. andTetraselmis 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 microalgaewere cultivated at two different photoperiod cycles (24:0 and 12:12 h light:dark). Maximum growthrates and cell concentrations for Nannochloropsis sp. and for Tetraselmis sp. were achieved atsalinities of 10 and 15‰, respectively. In terms of photoperiod, the maximum growth rates and cellconcentrations for both microalgae were obtained at photoperiod of 24:0 h light:dark. This studyshows that the cell concentrations and growth rates of both microalgae are highly dependent onsalinity and photoperiod.
