FIGURE 5.

Colors of different carotenoid-producing S. cerevisiae mutants. (A) Strains were cultured in YP medium without sugars at 30°C for 120 h. (B) Strains were cultured in modified YP medium with 30 g L^–1 xylose and 10 g L^–1 glucose at 30°C for 96 h; (C) SC105 was grown for 96 h on YP medium supplemented with different ration of sugars. Glucose, 40 g L^–1 glucose; 3:1, 30 g L^–1 xylose and 10 g L^–1 glucose; 2:1, 26 g L^–1 xylose and 13 g L^–1 glucose; 1:1, 20 g L^–1 xylose and 20 g L^–1 glucose; xylose, 40 g L^–1 xylose. (D) BY4741 and BL03-D-4 was grown on YPD plates. After 4 days of incubation at 30°C, the plates were photographed. (E) SC105 was grown for 96 h on YP plates supplemented with different sugars. xylose + glucose, 30 g L^–1 xylose and 10 g L^–1 glucose; Glucose, 40 g L^–1 glucose.
