Culture profiles of the pduL2::IPA strain when supplemented with hexose (fructose) and pentose (xylose) sugars. The consumption of fructose (A) or xylose (B) was monitored and products including acetate, acetone, formate, and IPA, in the culture supernatant were measured at each time point. Dry cell weight was calculated according to the OD. Data are presented as the mean with SDs of three biological replicates. Most error bars are smaller than the symbols of data plots
