Bioenergy application of Dunaliella salina SA 134 grown at various salinity levels for lipid production

Abstract The biofuels are receiving considerable attention as a substitute for petro diesel. For microalgae, the cell density or biomass and lipid contents are key components for biodiesel production. This study was conducted to develop favorable culture conditions for Dunaliella salina to maximize...

description	Abstract The biofuels are receiving considerable attention as a substitute for petro diesel. For microalgae, the cell density or biomass and lipid contents are key components for biodiesel production.

The effect of salinity (0.5 to 2.5 M NaCl) on the cell population, biochemical composition, and lipid output of Dunaliella salina was examined under a controlled environment for 21 days.
