Comparisons of ethanol production and residual sugars between three kinds of Z. mobilis strains in medium containing mixed sugars. Cultures were grown in RM medium (10 g/L yeast extract, 1 g/L KH₂PO₄, 1 g/L Carbamide, 0.5 g/L MgSO₄.6H₂O) with 170 g/L glucose and 60 g/L xylose as carbon source anaerobically at 32°C. All strains were tested by three parallel experiments. After 60 hours anaerobic fermentation, the average ethanol concentration of CP4, XU1 and HYMX3 was 72.7 g/L, 83.8 g/L and 88.9 g/L, respectively.
