“…Ethanol is one of the biofuels that more contributes to the reduction of environmental pollutants generated by the use of fossil fuels [8]. Its production from lignocellulosic biomass is a complex process because these materials requires pretreat-ment stages to achieve a degree of delignification that does not obstruct the fermentation of the sugars [2,12].…”

“…Some authors have dedicated their studies to find the most efficient pretreatment techniques for certain types of biomass in obtaining TRS. Many of these pretreatments have being analyzed as possible routes for biofuels industry [1,2,3,5]. In this work, the joint application of pretreatments to corn residues was made to analyze the degradation potential of this agroindustrial waste.…”

Biofuels from lignocellulosic biomass have the potential to reduce the fossil fuels consumption in the following years. However, the structure of these materials hinders degradation in the hydrolysis stage, which requires pretreatments that helps increase the production of fermentable sugars to obtain biofuel. Therefore, in this study three pretreatments were applied to corn stover biomass: Mechanical, with size reduction (0.5, 1, and 2 mm), followed by an alkaline pretreatment (NaOH 1.5% w/v) and subsequent acid pretreatment at different concentrations (H2SO4 2, 4, and 6% v/v). Finally an acid hydrolysis (1% H2SO4 v/v) of pretreated biomass was applied in order to evaluate the effect of different pretreatments in the amount of total reducing sugars (TRS).
