Figure 1: Experimental points (rhombs = hexoses, triangles = ethanol, circles = glycerine, stars= mass balance) and theoretic developments of hexoses conversion as a function of time of fermentation promoted by a S. cerevisiae strain (a) or a S. bayanus strain (b) in the adopted reaction medium ([D-glucose]t=0=1667 mmol⋅L-1, [D-fructose]t=0=1667 mmol⋅L-1).
