Carotenoid-producing yeast species such as Rhodotorula glutinis and Sporobolomyces roseus efficiently accumulated selenium from the growth medium. It was observed that incorporation of selenium into yeast cells during the growth inhibited production of beta-carotenoid and other carotenoid precursors (torularhodin and torulene). The yeasts with high content of the carotenoid pigments and selenium may be used for the preparation of a new type of antioxidant formula that could be directly applied for various human and animal diets. We have demonstrated that such a formula can only be produced by separate processes of the cultivation of red yeasts and a subsequent sorption of selenium into the cells.
产类胡萝卜素的酵母物种，如粘红酵母和玫瑰掷孢酵母，能有效地从生长培养基中积累硒。据观察，在生长过程中将硒掺入酵母细胞会抑制β-胡萝卜素和其他类胡萝卜素前体（红酵母红素和红酵母烯）的产生。富含类胡萝卜素色素和硒的酵母可用于制备一种新型抗氧化配方，可直接应用于各种人类和动物饮食。我们已经证明，这样的配方只能通过红酵母培养和随后将硒吸附到细胞中的单独过程来生产。
