Effect of ionic liquid pretreatment on enzymatic hydrolysis of cellulose was investigated in terms of the changes in the chemical and physical structure of the preparation. In this case, original cellulose isolated from sugarcane bagasse was subjected to ionic liquid ([Emim]Ac) dissolution at a mild temperature (90°C) followed by regeneration in water and subsequently hydrolyzed by commercial cellulases...
Seven hemicellulosic fractions were extracted with 10% KOH from delignified sugarcane bagasse for 10h at 20, 25, 30, 35, 40, 45, and 50°C, respectively. Chemical composition and structural features of all the fractions were investigated by a combination of HPAEC, GPC, FT-IR, 1D ( 1 H, 13 C) and 2D (HSQC) NMR spectra, and TGA-DTA. Notable differences in the molecular weights were observed...
