| Sumario: | The bagasse of Agave tequilana Weber is a lignocellulosic residue resulting from the production of tequila. At present, the bagasse is not industrialized, and poses a serious contamination problem. Thus, an ongoing research e ort is to explore the possibility to obtain added value chemicals from it. The aim of the present work was to determine the e ect of temperature, concentration of H2SO4 and reaction time on the hydrolysis of agave bagasse to produce fermentable sugars. The hydrolysis was performed in two sequential batch stages: (a) in the rst stage the optimal conditions were 151oC, 2% of sulfuric acid and 10 min of reaction, yielding 236 g/Kg dry matter and concentration of 26.9g/L of fermentable sugars, and (b) in second stage the optimal experimental conditions for the depolimerization of the biomass resulting from the rst stage were 175o C, 2% of sulfuric acid and 30 min of reaction, yielding 90 g/kg dry matter and concentration of 15 g/L of fermentable sugars. Total fermentable sugars yield from the sequential batch stages was 326 g/kg dry matter (48.50% of the theoretical value). |
