Abstract

The use of sweet sorghum as an alternative energy source, both saccharine and cellulosic, could be an
interesting option to complement production during the pre-harvest period. However, the pretreatment
phase of lignocellulosic materials remains a bottleneck for 2G ethanol-producing distilleries. In this study,
a 2 × 4 factorial design was used, with two sorghum cultivars (BRS 511 and Malibu) and four hydrogen
peroxide concentrations (1%, 2%, 3%, and 4%), to evaluate the effect of H2O2 pretreatment on 2G ethanol
production. The variables studied included the pretreatment yield, composition of neutral detergent fiber
(NDF), acid detergent fiber (ADF), and hemicellulose of the biomass after the pretreatments, enzymatic
hydrolysis coefficient, and estimated production of 2G ethanol. It was concluded that the highest ethanol
yield was obtained with 1% H2O2 pretreatment, for both BRS 511 and Malibu biomass.
