Optimization of alkali concentration in the pretreatment of sugarcane bagasse for ethanol production

This study was aimed for the investigation of effect pretreatment procedure alkaline, based on chemical arrangement, surface morphology, structural composition and enzymatic assimilation sugarcane bagasse sugars ethanol production. Alkali (0 to 8% w/v NaOH) assists reduce lignin portion (from 19.57±0.03% 9.91±0.02%) increase cellulose content treated SB 34.66±0.05% 63.58±0.05%) simultaneously. The optimal conditions alkali were NaOH charge at 100oC 90 min. Enzymatic digestibility significantly improved hydrolysis yield reached 89.59% glucose 61.23% xylose an prime level using Trichoderma viridae. Further hydrolysate (w/v) sample fermented by Saccharomyces cerevisiae convert sugar into 16.81±0.32% in 24 h. found be a treatment choice subsequent acquired production during fermentation.
