Description The effect of varying salinity and pH of the medium on growth and pigment ratios of Dunaliella cells in culture was studied. Cell growth was found to be optimal at pH 8 and at intermediate salt concentrations of 1-2 M NaCl. Ninety per cent acetone extracts of cells grown in media containing up to 2 M NaCl showed two distinct absorption peaks with maxima at 433 and 663 nm due to carotenoids and chlorophylls. The ratio of carotene to chlorophyll appeared to be maximum for cells grown in 1 M NaCl and to increase with the age of the cells in culture
