Immobilization of pectinase and lipase on macroporous resin coated with chitosan for treatment of whitewater from papermaking

► The dual-enzymes (pectinase and lipase) were immobilized on the macroporous resin coated with chitosan. ► The immobilized dual-enzymes exhibited high activities and excellent operational stability. ► The immobilized dual-enzymes were effective in removing anionic residues and pitch deposits in the whitewater from papermaking.
