Power generation from lignocellulosic biomass can contribute significantly to the energy
scope expansion, with regard to the alternative sources use focused on the renewable fuels
generation. However, the use of these sources still faces challenges related to different raw
materials exploration with potential use and technologies processes development that ensure
the technical and economic viability of generating 2G ethanol. The aim of this study was to
evaluate the ethanol production potential from aerial sweet potato (Ipomoea batatas (L.)
Lam.) (B) crop residues compared to elephantgrass materials (Pennisetum purpureum
Schum), cultivar Roxo and cultivar Napier by the hydrolytic action of three enzyme solutions:
two commercial enzymatic complexes (CTec2 e HTec2) and an enzyme extract obtained from
filamentous fungi isolated from Acromyrmex balzani. The experimental design was the
Factorial Scheme 3x3, in triplicate. It was checked on the sweet potato, the average yield of
37.42 mL/kg MS hydrolyzed with commercial enzymatic complexes and the elephantgrass,
this experiment confirmed its potential to be used in the renewable energy production, as it
presented average yield of 123.5 mL/kg MS hydrolyzed under the same conditions of biomass
sweet potato hydrolysis.
