Figure 1From: Pulsed addition of HMF and furfural to batch-grown xylose-utilizing Saccharomyces cerevisiaeresults in different physiological responses in glucose and xylose consumption phaseTime course of sugar, metabolite, and inhibitor concentrations after pulsing of inhibitors in the glucose and xylose consumption phase. After the inhibitor pulse, the response was divided into three phases in the two experiments. (A) For the cultivations pulsed during glucose consumption, the phases were defined as: glucose phase (12 to 17.25Â hours), co-conversion phase (19 to 22.5Â hours), and HMF phase (22.5 to 26Â hours). (B) For the cultivations pulsed during xylose consumption, the phases were defined as: xylose phase (26 to 29.5Â hours), co-conversion phase (29.5 to 32.5Â hours), and HMF phase (33.5 to 88.5Â hours). Squares, glucose; circles, xylose; triangles, ethanol; inverted triangles, glycerol; elongated diamonds, acetate; compressed diamonds, xylitol; red diamonds, HMF; purple squares, furfural. HMF: 5-hydroxymethylfurfural.Back to article page
