Comparison of the fermentation profiles of S. cerevisiae strain EJ4 grown on different carbon sources. a Cell growth, b sugar consumption, and c ethanol production of strain EJ4 during the fermentation of glucose, galactose, xylose, or cellobiose. Strain EJ4 was cultivated at 30 °C and 200 rpm in yeast synthetic complete broth containing 6.7 g/L yeast nitrogen base, 0.79 g/L complete supplement mixture, and 20 g/L one of carbon sources
