This work aimed to evaluate the best conditions for two types of pretreatments, hydrothermal and ultrasound, in order to obtain a material with high saccharide yield and low formation of inhibitors. For hydrothermal pretreatment, it was studied two temperatures, 160 and 180 ° C, and the times of 10, 20, 30, 40 and 50 minutes, under a solid:liquid ratio of 1: 10 (w / v). For ultrasound, the tests were carried out in a medium...
