Optimization of Micro Algal Biomass Production by the Method of Experimental Designs (Case of Dunaliella salina Teodoresco)

Dunaliella salina is a unique species of endemophilous microalgae. The objective of this work is to find the best conditions for the development of this microalga by optimizing four main parameters that directly influence the production of its biomass using the experimental design method. This statistical method, which results in the ordered sequence of trials of an experiment, each one acquiring new knowledge by controlling one or more input parameters to obtain results validating a robust model to produce this microalga of the salines in the western Algeria (salines of Arzew). For this purpose, this strain was grown under controlled conditions in a photo bioreactor. The results show that the alga Dunaliella salina grows and maximizes its yield for well-defined values of the four parameters.
