    Pretreatment of lignocellulosic biomass by Ν-methylmorpholine-Ν-oxide (NMMO), a solvent used in the textile industry to dissolve cellulose for production of regenerated cellulose fibers, was observed to enhance significantly enzymatic saccharification and fermentation. The enhancement was speculated to have been caused by reduced cellulose crystallinity after dissolution and precipitation processes. This work focused on assessing several physical changes and their correlations to enzymatic saccharification of pine flour after NMMO pretreatment. Results from microstructure, surface chemical composition, and cellulose accessibility complementarily illustrated the enrichment of cellulose on pine flour surface after NMMO pretreatment. Cellulose accessibility was highly correlated to the overall glucan conversion rate. Changes in crystallinity were correlated to the initial hydrolysis rate but not overall glucan conversion rate. Findings from this work may contribute to lignocellulosic bioenergy from development of novel pretreatment technologies utilizing NMMO.
