shows the ethanol produced after cooking pretreatment of
the CER in 100ml of deionized water of a dry weight of 16 g at 95 C
for 30 min, where the hydrolysate was extracted and underwent
fermentation. The aqueous phase and the solid CER were fermented
separately for 48 h with different loadings of yeast and at a
constant temperature of 30 C. Interestingly, the ethanol produced
under such conditions and the combinations thereof far exceeded
the untreated samples shown in the previous results. A combined
ethanol production rate of 2.3 and 2.7 g h1 kg1 dry substance,
respectively, showed a linear increase in relation to the weight of
yeast and the aqueous and solid fractions
