Immobilization of Burkholderia cepacia lipase on functionalized ionic liquids modified mesoporous silica SBA-15

► The kind of functional groups in imidazole ring of ILs affects the properties of immobilized lipase. ► Pore structure changes and stronger enzyme-support surface interactions lead to various enzymatic properties. ► This work expands the application of ILs modified mesoporous materials to lipase immobilization.
