- Resumo: The feasibility of operating biorefineries depends on the generation of new products with high added value and that use all the lignocellulose fractions (lignin, hemicellulose and cellulose) (FERRAZ, 2014; CHANDEL et al., 2021). In this sense, to obtain these fractions, pretreatment steps are required to overcome the recalcitrance of lignocellulosic biomass. As an example of pretreatment, the alkaline sulfite chemithermomechanical process provides high solids yield and high pretreated solids digestibility associated with partial delignification and xylan removal (ZHANG et al., 2016; MENDES et al., 2018). The pretreated solids is also amenable for xylanases treatment, providing low molar mass xylans with lignin contamination (SPORCK et al. 2017). It is also known that sugarcane glucuronoarabinoxylans have ferulic acid(FA) residues esterified to arabinoses(HATFIELD et al. 2017). The presence of hydroxycinnamic acids or residual lignin opens the possibility of enzyme-mediated oxidation on the phenolic hydroxyl groups of these molecules, providing subsequent xylan cross-link.
