Comparative Study of Alkali and Acidic Cellulose Solvent Pretreatment of Corn Stover for Fermentable Sugar Production
As an immerging lignocellulose pretreatment strategy, cellulose solventbased pretreatment can break down interand intra-molecular hydrogen bonds and disrupt the rigid structure of cellulose. Two cellulose solvent pretreatments were examined and compared in this study: NaOH/urea and concentrated phosphoric acid. Pretreated corn stover substrates were characterized by optical microscopy, confocal...
متن کاملFungal Pretreatment of Corn Stover Fractions for Ethanol Production
Ethanol produced from biomass, such as corn grain or sugar cane, is a renewable fuel that helps lessen dependence on petroleum-based fossil fuels. Currently, the majority of ethanol production in the United States utilizes corn grain, which supplied about 14 billion gallons of ethanol to the market in 2012. In the near future, corn supplies for ethanol are expected to be limited due to concerns...
متن کاملSupercritical carbon dioxide pretreatment of corn stover and switchgrass for lignocellulosic ethanol production.
Supercritical CO(2) (SC-CO(2)), a green solvent suitable for a mobile lignocellulosic biomass processor, was used to pretreat corn stover and switchgrass at various temperatures and pressures. The CO(2) pressure was released as quickly as possible by opening a quick release valve during the pretreatment. The biomass was hydrolyzed after pretreatment using cellulase combined with β-glucosidase. ...
متن کاملAlkaline twin-screw extrusion pretreatment for fermentable sugar production
BACKGROUND The inevitable depletion of fossil fuels has resulted in an increasing worldwide interest in exploring alternative and sustainable energy sources. Lignocellulose, which is the most abundant biomass on earth, is widely regarded as a promising raw material to produce fuel ethanol. Pretreatment is an essential step to disrupt the recalcitrance of lignocellulosic matrix for enzymatic sac...
متن کاملPretreatment on corn stover with low concentration of formic acid.
Bioethanol derived from lignocellulosic biomass has the potential to replace gasoline. Cellulose is naturally recalcitrant to enzymatic attack, and it also surrounded by the matrix of xylan and lignin, which enhances the recalcitrance. Therefore, lignocellulosic materials must be pretreated to make the cellulose easily degraded into sugars and further fermented to ethanol. In this work, hydroth...
