Abstract: | The growth and carotenoid production of Phaffia rhodozyma in fed-batch cultures with different feeding methods and grown at specific growth rates similar to the batch culture was compared. With constant feeding, exponential feeding, DO-stat and pH-stat fed-batch cultures of Phaffia rhodozyma, the highest biomass (17.4 g/l) and lowest carotenoid content (307 g/g cell) of Phaffia rhodozyma was from the DO-stat fed-batch culture. The lowest biomass (14.7 g/l) and highest carotenoid content (412 g/g cell) was from the exponential, fed-batch culture. |
