Characterization of a carotenoid-hyperproducing yeast mutant isolated by low-dose gamma irradiation.

International journal of food microbiology - 1 Aug 2004

Sun Namkyu, Lee Seunghee, Song Kyung Bin

Abstract excerpt

To isolate a carotenoid-hyperproducing yeast, Phaffia rhodozyma was treated by low-dose gamma irradiation below 10 kGy. Through repeated rounds of gamma irradiation and visual screening, a mutant 3A4-8 was isolated. It produced 3.3 mg of carotenoid per gram of yeast, 50% higher carotenoid content than that of the unirradiated strain. Glucose and peptone were the most suitable carbon and nitrogen sources for...
