- Immobilization and characterization of the Candida rugosa lipase enzyme on magnetic particles K.J. Dussán C.A. Cardona O. Giraldo Física, Astronomía y Matemáticas esterification enzyme activity Magnetic particles immobilized lipase Magnetic nanostructures have gained a remarkable interest in the last years both for basic research and applied studies. The use of magnetic nanostructures has been verified in biochemistry, biomedicine, and waste treatment among other fields. Their large magnetic moments gave them a broad range of applications which allow them to be transport and driven by external magnetic fields. The magnetic structures have also a great potential in biotechnological processes taking into account that they can be utilized as a carrier for enzymes in different biocatalytic transformations. In this work, the lipase enzyme Candida Rugosa was covalent bound to coated magnetic particles via glutaraldehyde activation in order to form a biocatalytic system. The analyses of XRD patterns indicated that the resultant magnetic particles were Fe3O4 with a mean diameter of 13 nm. The immobilized enzyme had a good behavior in the esterification reaction of oleic acid with butyl alcohol. 2012 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57030392013 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
