Hydrolysis of Red Beet Bagasse and Modeling of Hydrolysates for Bioethanol Production


 Red beets in Mexico are used the colorants industry, but their juice bagasse (RBB) can be carbohydrates for ethanol production. The present study aims to pretreatment of red beet using acid (H2SO4) and alkali (NaOH) improve availability sugars. Also, describe quantitatively hydrolysates microbial growth, substrate consumption, production with simulation data kinetics logistic, Pirt, Luedeking-Piret equations. Experiments H2SO4 at sterilization conditions resulted lower phenolic formation increased hydrolysis 32 %. Logistic, equations were production, respectively. In treatment, a significant mean difference was found (p < 0.05) mass reaction time. maximum yield 38 g/L total sugars 72 h obtained from 6 g RBB 0.5 N. 15 18 representing about 78 92 % theoretical yield.
