Abstract

The growing energy demand has driven the development of more efficient technologies and renewable
sources. Cassava stands out as an alternative for ethanol production due to its agronomic advantages
and processing characteristics. This study evaluated the effect of different enzymatic hydrolysis times of
starch in cassava cultivars, using a completely randomized design in a 4 x 3 factorial scheme, with four
cultivars (BRS Caipira, BRS Formosa, Mucuruna, and BRS Tapioqueira) and three hydrolysis times, with four
replications. The samples were subjected to enzymatic hydrolysis with α-amylase and amyloglucosidase,
evaluating hydrolysis coefficient, glucose concentration, fermentative yield, and ethanol production potential.
BRS Tapioqueira showed the highest production potential (329.11 ml/kg DM), while Mucuruna showed the
lowest yields. Fermentative yields ranged from 48.76% to 79.43%. The results highlight the importance of
optimizing the hydrolysis process according to specific characteristics of each cultivar for greater efficiency
in biofuel production.
