Fig. 4

Ethanol fermentation of pretreated sugarcane bagasse (SCB) using 1.5 mL GL/g-DS in GL–Ethanol pretreatment at 10% (w/v) solid loading, and yeast cell mass ratios of 1:3, 1:1, 2:1, and 3:0 (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 CSC-to-TSC = 1:3, CSC-to-TSC = 1:1, CSC-to-TSC = 2:1 and CSC-to-TSC = 3:0 using 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
