Superior activities of lipase immobilized on pure and hydrophobic clay supports: Characterization and catalytic activity studies.

Highlights: [•] Lipase was immobilized onto montmorillonite via adsorption and covalent binding. [•] The immobilized enzymes displayed enhanced catalytic efficiency and storage stability. [•] The activity of the free lipase in heptane was 0.51% of that in the aqueous medium. [•] The organomodified nanoclays would be suitable for industrial biotransformations. [Copyright &y& Elsevier]
