Pigment Production Improvement in AJB01 Using Design of Experiments.

The discovery of biopigments has received considerable attention from the industrial sector, mainly for potential applications as novel molecules with biological activity, in cosmetics or if aquaculture food supplements. The main objective of this study was to increase the production of carotenoid pigments in a naturally pigmented yeast by subjecting the yeast to various cellular stresses using design of experiments. The fungal strain AJB01 was isolated from a food sample collected in Barranquilla, Colombia, and one of the pigments produced was β-carotene.
