a The TCA cycle and GABA shunt pathway. 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 TCA cycle and GABA shunt pathway 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 Intracellular and extracellular accumulation of secondary metabolites, 4-hydroxyphenylacetate, benzoate, and phenylacetate, during cellobiose fermentation by strain EJ4 is presented in box-whisker plots
