Enzymatic hydrolysis of ionic liquid-pretreated celluloses: Contribution of CP-MAS 13C NMR and SEM

► [Emim]+[MeO(H)PO2]− is a suitable solvent for cellulose pretreatment. ► Reduced glucose production after 24 h is concomitant with cellobiose consumption. ► The efficiency of cellulose degradation could not be exclusively linked to the CrI. ► SEM shows a total loss of fiber organization which correlates with the high yields.
