Effect of temperature on gravity sedimentation of D. salina cells. a Recovery rate of carotenoid-accumulating cells cultured at 12.5% salinity. b Recovery rate of normal cells cultured at 12.5% salinity. c Recovery rate of carotenoid-accumulating cells cultured at 17.5% salinity. d Recovery rate of normal cells cultured at 17.5% salinity. The recovery rate of both cells in the gravity sedimentation was obtained after incubation for 4 h (white bar) and 18 h (hatched bars) at a given temperature. The recovery rate for each sample was determined in triplicate. All of the error bars represent the standard deviation of the mean
