Abstract excerpt
The carotenoid pigment astaxanthin (3,3'-dihydroxy-beta,beta-carotene-4,4'-dione) is an important component in feeds of aquacultural animals. It is produced as a secondary metabolite by the yeast Phaffia rhodozyma, and the isolation of rare mutants that produce increased quantities is limited by the lack of genetic selections. As a model system for enriching mutants increased in production of secondary...
