Introduction
Ionic liquids (ILs) are organic salts that exist as liquid at or close to room temperature. The unique physicochemical properties of ILs, such as negligible volatility, thermal stability, and relatively high polarity, make them interesting solvents for biocatalytic process. ILs are generally considered as green solvents that are good substitutes for traditional organic solvents. Also, ILs have been described as “designer solvents,” owing to their widely tunable physicochemical properties in terms of viscosity, density, hydrophobicity, polarity, and solvent miscibility by a suitable combination of different cations and anions (Fig. 1).
