Diversity of Cell Wall Composition and Saccharides Production with NaOH Pretreatment in Bioethanol Material: Miscanthus

Abstract:

Miscanthus is a high yielding bioenergy crop. In this study, we selected four typical pairs of Miscanthus samples which presents different cell wall compositions. After different concentration pretreatment of NaOH (0.5%, 1.0%, 4.0%), four species shows significant difference in saccharine production. Much more xylose was extracted in the supernatant solution; the average glucose yield of all samples was about 2.0% in the concentration of 4.0%, which while the xylose yield was 12.0%. Direct enzymatic hydrolysis of the NaOH presoaked biomass was found to give higher glucose yields of 11–26%, and low xylose yields of 11–15%.Lower concentration of NaOH resulted in distinct differences in both glucose and xylose hydrolysis yields.
