ABSTRACT Yeast cells capable of generating at least 1100 µg astaxanthin per gram and useful as a fish feed are disclosed. Mutagenisis of Phaffia rhodozyma using EMS and/or NTG is a preferred route to obtain these cells. Rupturing of the cells to release the pigment makes use of an alpha 1,3 glucanase containing enzyme. Methods of drying, concentrating and storing the cells are described.
