Fig. 2From: Identification of a novel metabolic engineering target for carotenoid production in Saccharomyces cerevisiae via ethanol-induced adaptive laboratory evolutionCharacterization of parental (BL03-D-4) and evolved (M3) strains. Carotenoid yields and biomasses of BL03-D-4 and M3 in YPD and YPM media after 96 h of incubation (a). Specific growth rates of BL03-D-4 and M3 under different concentrations of ethanol (b). Effect of different concentrations of ethanol on carotenoid yields of BL03-D-4 and M3 (c). Growth curves of BL03-D-4 and M3 in YPM media without ethanol stress (d). Error bars represent standard deviations of three replicatesBack to article page
