Fermentation of freeze-dried sugar syrups to ethanol. a Reconstituted mainline sugar syrup at an initial concentration of 150 g/L of fermentable sugars using both S. cerevisiae strain D5A and Z. mobilis strain 8b, b hydrolysed pressate syrup using S. cerevisiae strain D5A reconstituted at an initial concentration of 58.4 g/L fermentable sugars. Fermentable sugars are glucose and mannose for the D5A organism and glucose and xylose for the 8b organism. Results of duplicate experimental determinations shown
