摘要：
In this work was investigated the use of alternative technologies to improve the enzymatic hydrolysis of rice hulls. The use of supercritical CO2 as co-solvent and ultrasound-assisted hydrolysis was evaluated and the results were compared with a conventional procedure. Maximum yield of fermentable sugar obtained was about 16 g kg(-1) using conventional or ultrasound-assisted hydrolyzes. The yield obtained in the hydrolysis using supercritical CO2 was around 4.2 g kg(-1) as co-solvent. Enzymatic hydrolysis using the conventional procedure showed to be the best manner to obtain fermentable sugar from rice hulls since the alternative technologies employed did not lead to better results.
