Optimization of the Cultivation Conditions of the Green Algae Dunaliella salina by Using Simplex Method

The green algae Dunaliella salina offers great potential for the food industry due to its high ?-carotene content. To guarantee economic profitability of cultivation, growth conditions must be improved. Therefore, effects pH and salinity on cultivation alga D. were investigated optimized. simplex method was applied find optimum these two parameters maximize biomass cell number salina. found at 7 8 a salt content 50 g/L, with 1.09 1.11 respectively. highest final g/L. However, by using method, an product yield 64 g/L initial value 7.2. Thus, 1.23 mg/mL achieved. In single observation both parameters, 14 experiments conducted obtain satisfactory result, whereas eight runs only required method. This leads conclusion that is useful way drastically reduce experiments.
