MATEUS, Lady; HERNANDEZ, Orlando; VELASQUEZ, Mario  e  DIAZ, José de Jesús. Dilute sulfuric acid pretreatment of goliath grass (Pennisetum glaucum x Pennisetum purpureum) for ethanol cellulosic. Rev. colomb. biotecnol [online]. 2012, vol.14, n.1, pp.146-156. ISSN 0123-3475.

The goliath grass (Pennisetum glaucum x Pennisetum purpureum) was pretreated with different sulfuric acid concentrations (0.8, 1.2 y 2.0% (w/w)) from low to high temperatures (110, 130, 150, 170 y 190 °C) followed by enzymatic hydrolysis and SSF of remaining solids. The maximum yield was 117 mg of ethanol/g biomass to 190 °C and 1.2 % (w/w) of sulfuric acid.

Palavras-chave : lignocellulosic ethanol; hemicellulose; cellulose.
