Magnetic Modified Natural Polymers for Biotechnological Application

Abstract:

Magnetic microparticles were formulated by encapsulating magnetite nanoparticles with cellulose acrylamidemetyl propionate acetate (CAPA) chemically modified with acrylamide (AM) in order to immobilize, through covalent bonds, enzymes. The microparticles were characterized by means of scanning electron microscopy and thermogravimetry. The magnetic CAPA + AM microparticles display a quite regular spherical geometry with smooth surface and a magnetite load corresponding to 11.2% of the total mass. These particles were considered as convenient supports for enzyme immobilization in biodiesel transesterification process.
