| 摘 要： | 1 Introduction In recent years, carotenoids have received increasing attention as they have extensive use in medicine, cosmetic, chemistry, food industry and feed industry. In industry, carotenoid and astaxanthin can be used as the additives of food or feeds. Carotenoids can also serve as the precursor of vitamin A in mammals. In recent years, many types of carotenoid have aroused extensive interest because of their many beneficial effects on human health. For in-stance, lycopene and astaxant…

| Abstract: | After a serial of UV, EMS and NTG mutagenesis, a mutant named MM of the red marine yeast strain Rhodotorula sp.hidai was obtained. The mutant MM could produce 603.93 μg g-1 of carotenoid within 5 days in the medium containing 4.0 g sucrose,1.5 g yeast extract, 0.1 g MgSO4, and 100 mL of sea water, with pH 6.0 and at 30 ℃, while only 213.18 μg g-1 of carotenoid was produced by the wild type under the same conditions. |
