Resumo Inglês:

The aim of this study was to evaluate the performance of enzymatic hydrolysis of acid or alkali pretreated sugarcane
bagasse for the production of fermentable sugars. The first step consisted of selection of commercial enzymes
presenting the highest cellulolytic activities. After selection of four enzymes: HPL, CL, P1 and P4, their
performances were tested in the bagasse pretreated with acid and alkali. The sugar content of the hydrolysates was
analyzed by anion exchange liquid chromatography. Data showed that the joint action of 0.5% acid pretreatment,
121ºC, 30 minutes and enzyme CL provides the best results, 67.25 g of hexose and 148.13g of pentose per kg of dry
