Industrially relevant hydrolyzability and fermentability of sugarcane bagasse improved effectively by glycerol organosolv pretreatment
BACKGROUND Previous work has demonstrated that glycerol organosolv pretreatment can effectively improve the hydrolyzability of various lignocellulosic substrates. This pretreatment process strategy is ideal to integrate a commercially successful lignocellulosic and vegetable oil biorefinery industry. However, industrially relevant high-solid-loading hydrolyzability and fermentability of the pre...
متن کاملGlycerol carbonate as green solvent for pretreatment of sugarcane bagasse
BACKGROUND Pretreatment of lignocellulosic biomass is a prerequisite for effective saccharification to produce fermentable sugars. In this study, "green" solvent systems based on acidified mixtures of glycerol carbonate (GC) and glycerol were used to treat sugarcane bagasse and the roles of each solvent in deconstructing biomass were determined. RESULTS Pretreatment of sugarcane bagasse at 90...
متن کاملPretreatment Strategies for Delignification of Sugarcane Bagasse: A Review
The valorization of agro-residues by biological routes is a key technology that contributes to the development of sustainable processes and the generation of value-added products. Sugarcane bagasse is an agro-residue generated by the sugar and alcohol industry in Brazil (186 million tons per year), composed essentially of cellulose (32-44%), hemicellulose (27-32%) and lignin (19-24%). The conve...
متن کاملComparison between Wet Oxidation and Steam Explosion as Pretreatment Methods for Enzymatic Hydrolysis of Sugarcane Bagasse
Alkaline wet oxidation and steam explosion pretreatments of sugarcane bagasse were compared with regard to biomass fractionation, formation of by-products, and enzymatic convertibility of the pretreated material. Wet oxidation led to the solubilisation of 82% of xylan and 50% of lignin, and to a two-fold increase of cellulose content in the pretreated solids, while steam explosion solubilised o...
متن کاملCharacterisation of Non-Cellulosic Heteropolysaccharide from Sugarcane Bagasse - Sequential Extraction with Steam Pretreatment and Alkali
Two-stage treatments of sugarcane bagasse with steam and alkaline peroxide were performed and the hemicelluloses extracted were characterized by chemical methods, SEC-MALLS, FT-IR and 13C NMR. The hemicellulose from steam pretreatment was found to contain galacto-arabinoxylans while alkaline peroxide extraction yielded predominately linear arabinoxylans.The present studyshowed a promising seque...
