Fig. 3

Ethanol fermentation of pretreated sugarcane bagasse (SCB) using 0.8, 1.0, and 1.5 mL GL/g-DS in GL–Ethanol pretreatment at 10% (w/v) solid loading, and a yeast cell mass ratio of 1:2 (w/w) common S. cerevisiae (CSC) to thermophilic S. cerevisiae (TSC). Fermentation conditions: 150 rpm, 35 °C, pH 5.5, and 120 h. Square, circular, upright triangle and inverted triangle symbols represent untreated, 0.8 mL GL/g-DS, 1.0 mL GL/g-DS and 1.5 mL GL/g-DS pretreated SCB, respectively. a Sugars (glucose and xylose) concentration; b Ethanol yield (% of the theoretical) and ethanol concentration; c Glycerol concentration; and d Acetic acid concentration
