【Abstract】 Mutagenesis of phaffia rhedozyma was attempted with NTG. Carotenoid synthesis inhibitors,β-ionone and diphenylamine were used in selection of the mutants phaffia rhedozyma with a high yield of carotenoid. One of these mutants was mutagened repeatedly, and the carotennoid of the re mutant was 82.9% higher than the parent. Five yeast growth inhibitors were tested and CuSO4 was the most effective.更多还原
