MBSP method proposed in this study offers an alternative approach to efficient convert nonwoody lignocellulosic biomass to ethanol. After MBSP, about 90% of lignin and 80% of hemicellulose was removed from biomass and more than 90% cellulose conversion of substrate was achieved for 48 h hydrolysis. In bio-ethanol production using MBSP, 6.19 kg raw corn stover could produce 1 kg ethanol. Besides these, the great advantage of MBSP is that it could protect sugars from excessive degradation, prevent fermentation inhibition formation and directly convert the hemicelluloses into xylooligosaccharides as higher-value products.
