    Haemotococcus pluvalis is a microalgae specie which is recognized as a potential source of astaxanthin accumulation. By selecting two governing cultivation parameters in the form of illumination and initial phosphorous concentration, the optimum stage of accumulated astaxanthin quantity was observed during the experiment. The cultivation of microalgae was conducted for three experimental setups in photo-bioreactors under varied light intensities and initial phosphorus concentrations, with external aeration of constant rate. The biomass growth and accumulated astaxanthin content were evaluated by spectrophotometric method. As by results obtained, the maximum of astaxanthin quantity was observed under the light intensity of 3500Lux and phosphorous concentration of 1.75mM.
