Palabras clave: Azucares reductores, Bioconversión, Celulasas, Cromatografía de Gases, Saccharomyces cerevisiae, etanol

Resumen

El objetivo de la presente investigación fue hidrolizar el polvillo de arroz a azucares reductores y mediante fermentación alcohólica obtener bioetanol. Se prepararon nueve soluciones de polvillo de arroz molido (8 %, 13 % y 18 %) y agua purificada e inoculados con conidios de Trichoderma spp en concentraciones (0,2 g/L, 0,4 g/L y 0,6 g/L), los cuales se incubaron a 30°C por 144 horas.   Mediante el método DNS (3, 5 ácido di nitrosalisilico), se cuantificó los azúcares reductores: tratamiento A: 4,32 ± 0,08%, B: 5,27 ± 0,07%, C: 5,10 ± 0,01%, D: 5,53 ± 0,12%, E: 8,24 ± 0,06%, F: 6,37 ± 0,07%, G: 5,13 ± 0,02%, H: 7,19 ± 0,26%, I: 9,69 ± 0,18% y el etanol mediante cromatografía de gases. El tratamiento que presentó mayor porcentaje de bioconversión fue el tratamiento I (18 % y 0,6 g/L de inóculo), donde la concentración de glucosa, fue 9,88%, y el rendimiento de etanol fue de 5° GL. En conclusión, es posible hidrolizar los carbohidratos totales presente en el polvillo de arroz en azucares reductores y posterior fermentación alcohólica.
