摘　　要：研究了不同碳源及含量对粘性红酵母(Rhodotorula mucilaginosa)WP3生长及类胡萝卜素积累的影响。结果表明,在所研究的碳源中,葡萄糖有利于生长,而果糖有利于类胡萝卜素积累。在碳源含量为40 g/L,果糖和葡萄糖比例为7∶1,果糖含量为35 g/L,葡萄糖含量为5 g/L时,粘性红酵母WP3的生物量为7.94,类胡萝卜素产量达到556.84μg/L,对粘性红酵母生长及类胡萝卜素合成有利。The effects of different carbon sources and contents on the growth of Rhodotorula mucilaginosa WP3 and the accumulation of carotenoids were researched. The results showed that in the carbon sources studied, glucose was the most beneficial to cell growth, while fructose was the most beneficial to the accumulation of carotenoids. In the conditions of carbon sources 40 g/L, fructose and glucose ratio 7：1 （fructose 35 g/L and glucose 5 g/L）, the biomass ofR. mucilaginosa WP3 was 7.94 and carotenoids yield was up to 556.84 μg/L, which indicated that the conditions were benefi- cial to the growth of R. mucilaginosa and the accumulation of carotenoids.
