Reducing Sugar Production from Bagasse by Acid Hydrolysis

Abstract

The effect of H2SO4 pretreatment for the conversion of rice straw to reducing sugars. The optimization of pretreatment was performed using a three factors Fractional Factorial Design (FFD). The H2SO4 concentration (3, 6 and 9 % (w/v)), temperature (30, 60 and 90 °C) and time (30, 60 and 90 min). The optimal conditions, which obtained the highest reducing sugar yield of 0.999 g/L, were performed at 9 % (w/v) H2SO4 , 30 minutes and 90 °C.
