Fed-batch essays using yeast Phaffia rhodozyma were performed to obtain high astaxanthin concentrations. The yeast was grown over an inexpensive media obtained from the Yucca fillifera date. Feeding was carried out through implantation of a pH-stat control system. Biomass (28.7 mg/l) and pigment (18 mg/l) concentration three folded those that were obtained by previous batch cultures.
