Bioethanol fermentation performances of S. cerevisiae YL23-1 by RCF pulps’ hydrolysates with 12 wt% of solid loading. The effect of the initial liquor proportion of 2-PrOH:H2O (v/v) on bioethanol production were analyzed. Bioethanol fermentation performances using the RCF pulps’ hydrolysates from the groups of a 1:9 (v/v), b 3:7 (v/v), c 5:5 (v/v), d 7:3 (v/v), and e 9:1 (v/v) of 2-PrOH:H2O. f Comparison of the bioethanol concentration and yield in different groups
