Fathi and Asem (2013) while working with Chlorella, also reported that high salinity (50 gL-1) leads to
decrease in β-carotene content. Pisal and Lele (2005) on the basis of their experiments on unicellular green
alga Dunaliella salina suggested that the cells show unbalanced physiological conditions under the
influence of various stresses leading to increased β–carotene content.
