Pigment Production Improvement in Rhodotorula mucilaginosa 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. main objective this study was to increase production carotenoid pigments a naturally pigmented yeast by subjecting various cellular stresses using design experiments. fungal strain Rhodotorula mucilaginosa AJB01 isolated sample collected Barranquilla, Colombia, and one produced ?-carotene. This subjected stress conditions, including osmotic different salts, physical ultraviolet (UV) light, light photoperiods. optimal growth conditions were determined be 1 min UV 0.5 mg/L magnesium sulfate, an 18:6 h light/dark period, which resulted yield 118.3 µg per gram yeast.
