Potential of Tunisian Alfa (Stipa tenassicima) fibers for energy recovery to 2G bioethanol: Study of pretreatment, enzymatic saccharification and fermentation

These yields were increased after enzymatic saccharification to reach 22.7 g/L of reducing sugars. The fermentation of the aforementioned hydrolysate was efficient with ethanol production being 36.36% of theoretical maximum.
