Descrição: dc.descriptionIn this study, a Eucalyptus by-product was fractionated into cellulose and lignin by pretreatment with NaClO2 to obtain α-cellulose, and hydrothermal pretreatment followed by sulfite-NaOH to obtain cellulose and lignin. The recovered celluloses were chemically and structurally characterized and enzymatically hydrolyzed using commercial enzyme preparations. The α-cellulose and cellulose treated with sulfite-NaOH had cellulose contents of 70.1% and 61.1%, respectively. α-cellulose hydrolyzed with Celluclast showed potential for cello-oligosaccharides formation, resulting in a maximum conversion of 30%, while Cellic CTec 2 resulted in 100% conversion to glucose, whereas cellulose treated with sulfite-NaOH showed potential for conversion to glucose with Cellulcast (44%) and Cellic CTec 2 (78%). The liquor from the sulfite-NaOH process resulted in a 20.8% yield of sulfonated lignin recovery. The use of different pretreatment techniques for the Eucalyptus by-product can be alternatives for the generation of products with high added value and commercial potential, such as cello-oligosaccharides, glucose, and sulfonated lignin.-
