a The most common type of glycolysis, the Embden–Meyerhof–Parnas (EMP) pathway, and the TCA cycle. The normalized abundance levels of the intracellular metabolites of S. cerevisiae strain EJ4 grown on galactose (GAL), glucose (GLC), xylose (XYL), or cellobiose (CB) related to the EMP pathway and TCA cycle are shown in box-whisker plots. The x-axis labels in the box-whisker plots represent the four different carbon sources with two different sampling timepoints, 1, mid-exponential phase; 2, late-exponential phase. b Extracellular accumulation of trisaccharide, glycerol, and fumarate during glucose fermentation by strain EJ4 is presented in box-whisker plots
