pretreatment was performed at 50 ◦C for 30 min, while the alkali treatment performed
with 12% NaOH at 0 ◦C for 3 h. The pretreatments resulted in improving the subsequent enzymatic hydrolysis
to 79–92% of the theoretical yield. The best hydrolysis performance was obtained after pretreatment
bn the best case, the hydrolyzate of NaOH-ultrasound pretreated bagasse followed by 24 h
fermentation resulted in about 81% of the corresponding theoretical ethanol yield. Furthermore, the
highest volumetric ethanol productivity was observed in the hydrolyzates of NaOH pretreated bagasse,
especially after ultrasonication in pretreatment stage.
