Characterisation of Non-Cellulosic Heteropolysaccharide from Sugarcane Bagasse - Sequential Extraction with Steam Pretreatment and Alkali
نویسنده
چکیده
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 sequential extraction for isolating arabinoxylan hemicelluloses with different degree of branching, molar mass and functional group from sugarcane bagasse. Consequently, products with a high aggregated value could be developed using this xylan-rich fraction as an ingredient for industrial products.

Liquid Hot Water and Steam Explosion Pretreatment of Sugarcane Bagasse for Enzyme Production by a Sequential Solid-state and Submerged Method
RESUMO – The use of sugarcane bagasse on enzyme production is a promising alternative for reducing the costs of second generation ethanol. However, a pretreatment step is required to increase cellulose and hemicellulose accessibility. Here, the influence of Liquid Hot Water (LHW) and steam explosion (SE) pretreatments in cultivations with three Aspergillus strains were investigated. A new seque...

متن کاملUnderstanding mild acid pretreatment of sugarcane bagasse through particle scale modeling.
Sugarcane bagasse is an abundant and sustainable resource, generated as a by-product of sugarcane milling. The cellulosic material within bagasse can be broken down into glucose molecules and fermented to produce ethanol, making it a promising feedstock for biofuel production. Mild acid pretreatment hydrolyses the hemicellulosic component of biomass, thus allowing enzymes greater access to the ...
متن کاملComparative study on chemical pretreatment (acid and ozone) methods for improving enzymatic digestibility of sugar cane bagasse
Sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. So it is can be used as a sugar source in many processes. Lignin and hemicellulose must be removed before hydrolysis of cellulose. Several different pretreatment approaches have been studied. The purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...
