The comparison of ethanol production by Zymomonas mobilis utilizing sugar-cane mo/asses in "natural" and pre-treated with invertase has been carried out. Batch fermentation were performed for 48 hours and sugar concentration was 120 g/L at 30°C. The highest ethanol concentration was 39,5 g/L when mo/asses was pre-treated with 1 mL of invertase, The value is 52,8 % higher than mo/asses in "natural" was used.
