Abstract

This study aimed at analysing the influence of enzymatic pre-hydrolysis of sugarcane molasses with α-amylase and amyloglucosidase on the subsequent alcoholic fermentation, with the objective of increasing bioethanol productivity. Sugarcane molasses must was treated with the amylolytic enzymes and then submitted to alcoholic fermentation for 8 h at 32oC, in presence of baker’s yeast (Saccharomyces cerevisiae) and nutrients. Analyses carried out for sugars and ethanol yield showed the efficiency of the pre-treatment, concerning the increase in fermentable sugars. The best result for the treatment of molasses with the two enzymes yielded a 10.2% increase of sugars in comparison to…
