Lutein is presently produced from marigold. Its market is divided into food colorant, nutraceutical, pharmaceutical, and animal and fish feed. But mass culture of marigold need large land area and it is easily influenced by season and climate. Microalgae have received enormous interests as one of the most promising alternative source of lutein since they can be cultivated in bioreactors and thus are a continuous and reliable source of the product. In this study, one of the species of microalga, Chlorella vulgaris is used that can be a primary food source by providing high nutrition quality. Statistical optimization of growth media was performed for a higher concentration of lutein by C. vulgaris heterotrophically cultivated. The effect of media composition on the lutein concentration of C. vulgaris was examined using fractional factorial design (FFD) and central composite design (CCD). The results show that lutein productivity increased in lutein-optimized media. Although speculative, this result may prove the potential of C. vulgaris as a lutein source.
