A MUTANT STRAIN OF XANTHOPHYLLOMYCES DENDRORHOUS HAVING ENHANCED PRODUCTIVITY OF ASTAXANTHIN

摘要

The invention xanthosine Philo My process dendeuro hose (Xanthophyllomyces dendrorhous) relates to the mutants, and a method of manufacturing the same, and more particularly beta involved in the biosynthetic pathway of astaxanthin by mutation - on the ionone (β -Ionone) relates to astaxanthin having useful biological activity by having acquired resistance to yeast mutant Xanthomonas Philo My process dendeuro hose JH1 (Xanthophyllomyces dendrorhous JH1) KCCM- 10580 , which can produce more than 15 times more efficient than the parent strain.; The JH1 strains developed in the present invention, in spite of indicating a slower growth rate than the parent strain (wild-type) by mutation and, and the carotenoid than 14 times the mass production than the parent strain, especially more than 15 times the astaxanthin than parent strain The mass production.
