The results of the experiments showed that all
Dunaliella salina strains referred salinity ranging from 1.5
M to 2 M for optimal growth. Also, the data suggested
that growth performance for these Dunaliella was better at
light intensity of 50 µmol photon/m2
/s. Based on these
optimal salinity and light intensity, we will apply stress
conditions for carotene induction on these strain in our
next experiments.
