Titanium dioxide (TiO2) and Fe3O4 magnetite particles were coated on spherical Kissirises; and glucose oxidase (GOx) enzyme was immobilized on Kissiris\Fe3O4\TiO2 by physical adsorption. This catalyst was analyzed by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT–IR) measurements. Performance of the prepared biocatalyst in decolorization of Malachite Green dye was investigated. The optimal operation parameters were 20 mg\L, 20 mM, 5.5 and 4 C for initial dye concentration, initial glucose concentration, pH and temperature, respectively. Under these conditions, 95% Malachite Green decolorization efficiency was obtained after 150 min of reaction by using 1 g of prepared heterogeneous bio–Fenton catalyst.<\div>
