Abstract The biomass and photosynthetic pigment contents were detected in green alga Dunaliella salina cultured in seven kinds of culture media to screen out the optimum liquid medium applied in the large-scale production of the green alga .The results showed that the best growth and the maximal accumulation of pigments were observed in the green alga cultured in the media of Pick (1994) ,and modified Johnson and modified Pick (2006) ,with different optimal conditions for growth and photosynthetic pigments accumula-tion .The maximal biomass was found in the green alga cultivated in modified Pick culture medium (2006) and the maximal contents of photosynthetic pigments in modified Johnson culture medium .According to input-output ratio ,it was found that modified Pick culture medium (2006) was best for the large-scale pro-duction of green alga D .salina because of higher biomass yield and pigment content ;while modified John-son culture medium was better for the large-scale pigment content production .
