Abstract
The need to increase production of ethanol the use of lignocellulosic materials as a source of fermentable sugars have been a good approach. In Brazil, the sugar cane bagasse is an abundant lignocellulosic material with great potential to be used as a primary source in the biorefineries. The lignocellulose is composed of lignin and sugars polymers, as cellulose and hemicellulose, compose…
