ILs as emerging solvents for the pretreatment of lignocellulosic biomass.
ILs pretreatment enhanced enzymatic delignification significantly.
One-step hydrolysis can be employed in ILs that maintain cellulase activity and stability.
Temperature and biomass loading during IL pretreatment affected hydrolysis rate notably.
Development of in situ hydrolysis of biomass can be integrated for bioethanol production.
