    Author: Jirasripongpun K, Pewlong W, Kitraksa P, Krudngern C.
    Journal: Lett Appl Microbiol; 2008 Aug; 47(2):112-6. PubMed ID: 18673431.
    Abstract:
    AIMS: To select a carotenoid-hyperproducing mutant and to formulate pineapple juice as a carotenoid production medium. METHODS AND RESULTS: Yeast strain of Xanthophyllomyces dendrorhous mutant GM 807 (derived from gamma irradiation) and the mutant n78 (from neutron irradiation) were selected based on higher carotenoid production in diluted pineapple juice as a medium. The selected strain was evaluated under various concentrations of pineapple juice. The results obtained in the study demonstrate that the mutant GM 807 enhanced production by 65.8% when using pineapple juice as medium at 10% dilution in place of yeast malt medium. CONCLUSION: Pineapple juice could be used as a sole medium for carotenoid production. SIGNIFICANCE AND IMPACT OF THE STUDY: Our results provide useful information for the design of production media for carotenoids to be used in various applications.
