Fig. 2

Fermentation profile in standard condition for the yeasts ER, BG-1, CAT-1, PE-2, and SA-1, in the four conditions: A standard condition, B initial cell concentration of 0.02%, solids content of 30% and temperature of 32 ºC; C initial cell concentration of 0.02%, solids content of 30% and temperature of 35ºC; D initial cell concentration of 0.02%, solids content of 35% and temperature of 32 ºC. The data points in the figure are means of triplicate runs and error bars represent standard deviations. Solid lines refer to ethanol concentrations (% v/v), and dotted lines refer to glucose concentrations (% w/v). E Maximum ethanol concentration (v/v%) at the end of fermentation. Statistically significant differences (Tukey’s test at 95% confidence interval) were highlighted by an asterisk (*)
