Obtención de azúcares fermentables a partir de pasto elefante (Pennisetum purpureum).

The present study shows the results of obtaining fermentable sugars using elephant grass (Pennisetum purpureum) feedstock. The concentration effect of acetic acid (CH3COOH) and sodium chlorite (NaClO2) was assessed on the removal of lignin hemicellulose complex. A comparison was made about method, using basic pretreatment with sodium hydroxide (NaOH) and hydrogen peroxide (H2O2). The Saccharification step is carried out by enzymatic hydrolysis method that is performed using cellulase and β-glucosidase. The results show in the case of pretreatment with NaClO2 and CH3COOH a percentage of saccharification of 80.87% compared to NaOH pretreatment with a percentage 56.82% and hydrogen peroxide with a percentage of 44.75%.
