Heterofunctional hydrophilic-hydrophobic porous silica as support for multipoint covalent immobilization of lipases: application to lactulose palmitate synthesis.
Lipase-catalyzed synthesis of sugar esters, as lactulose palmitate, requires harsh conditions, making it necessary to immobilize the enzyme. Therefore, a study was conducted to evaluate the effect ofExpand

Immobilisation and stabilisation of β-galactosidase from Kluyveromyces lactis using a glyoxyl support
Abstract β-galactosidase from Kluyveromyces lactis was covalently immobilised on a Glyoxyl Sepharose (GS) support by multi-point attachment. The enzyme immobilisation process was very efficient; theExpand
