Rhodotorula mucilaginosa was cultivated in a yeast propagator, for the production of biomass and carotenoids. A spray-dried preparation of the yeast was incorporated into the diets of laying chickens for the promotion of egg yolk color. Several aspects of the effect of media on growth and carotenogenesis of pigmented yeast were examined. Addition of 1 to 2% of Rhodotorula yeast to the feeding mixture considerably improved egg yolk color. The possibility of using carotenogenic yeasts as a feed supplement is suggested.
粘红酵母在酵母扩培器中培养,用于生产生物质和类胡萝卜素。将喷雾干燥的酵母制剂添加到蛋鸡日粮中以改善蛋黄颜色。研究了培养基对有色酵母生长和类胡萝卜素生成影响的几个方面。在饲料混合物中添加1%至2%的粘红酵母可显著改善蛋黄颜色。提出了使用产类胡萝卜素酵母作为饲料添加剂的可能性。
