Ionic liquid pretreatment as emerging approaches for enhanced enzymatic hydrolysis of lignocellulosic biomass

Ionic liquids (ILs) have been increasingly exploited as solvents and/or reagents in many applications due to their “green” properties as well as their tunable physicochemical and biological properties. One of them is the pretreatment of lignocellulosic biomass prior to enzymatic hydrolysis for bio...
