Abstract : This study was to examine the feasibility of using alternative low cost technique for Dunaliella salina cultivation to be implemented in Saudi Arabia. This work used Dual-phase system to cultivate D. salina . The first stage was aimed to maximize D. salina biomass and minimize nutrients cost through using different dilution of Johnson's medium (1:0, 1:1, 1:2, and 1:3). The second stage was used two types of water: (partially treated sewage water PTSW) and (discharged desalination water DDW) as a shock to enhance specific biochemical composition product. Protein, carbohydrate, lipid, and beta-carotene of the biomass were measured before and after shock to study the effects of shock on biochemical content. The results showed that the protein and carbohydrate content were higher in the first stage (9.53-13.6 pg/cell;10.3-14.37 pg/cell) respectively, whereas the highest lipid and β-carotene were recorded in DDW shocked cultures (5.66-15.13 pg/cell;16.17-38.93 pg/cell) respectively, compared to lower values in PTSW shocked cultures. This study indicates that the application of discharged desalination water in a Dual-phase culturing system to grow D. salina has a great interest if D .salina cultivation is targeted for lipids and β-carotene production.
