Immobilization of β-glucosidase on a magnetic nanoparticle improves thermostability: Application in cellobiose hydrolysis

► Immobilization of β-glucosidase on a functionalized magnetic nanoparticles was achieved. ► Enhancement in β-glucosidase thermostability was observed upon immobilization to nanomaterials. ► Nanomaterial immobilized enzyme was used for cellobiose hydrolysis. ► Nanoparticle-enzyme conjugate retained more than 50% enzyme activity up to the 16 cycles of substrate hydrolysis.
