RÉSUMÉ
Phaffia rhodozyma is a good strain for astaxanthin production. An over-producing mutant YB-20-29 was obtained by means of Cs137-?ray and N-methy1-N'-nitro-N-nitrosoguanidin (NTG) treatment. The biomass for this strain by shake culture was 36.32 g/L, the pigment content was 1216.0 ?g/g, an increase of 308% compare to o-riginal strain. The astaxanthin content in broth was 30.9?g /mL. It was a potential strain for astaxanthin over-production.
