Ethanol production from sugarcane bagasse: Use of different fermentation strategies to enhance an environmental-friendly process.

Ethanol production by simultaneous saccharification and fermentation (SSF) using sugarcane bagasse as substrate was developed using batch and fed-batch mode. Acid, alkali, hydrothermal and hydrogen peroxide pretreatments to the sugarcane bagasse were tested. Experiments were carried out to optimize the enzyme load of cellulases and β-glucosidase.
