Fermentation profile of ethanol adapted strains in the presence and absence of added ethanol. For all fermentations, the cellobiose concentration was 50 g/L (146 mM). Panels A and B show cells grown in chemically defined medium (MTC-5). Panels C and D show cells grown in rich medium (CTFUD). The bottom two panels (B and D) show cells grown in the presence of 10 g/L added ethanol. In panels C and D, each adapted strain is next to its parent strain. Error bars represent one standard deviation, n = 3 biological replicates
