The catalytic behaviour under isothermal conditions of two different membranes loaded with β-galactosidase was investigated. One membrane (M1) was constituted by a nylon sheet grafted with methylmethacrylate by means of chemical grafting. The other, (M2), was prepared by a double chemical grafting: the first one with styrene (Sty) and the second one with methylmethacrylate. Membrane activity was characterized as a function of temperature, pH and substrate concentration. The role of Sty in increasing membrane hydrophobicity has been discussed. Membrane M2 was found to be better suited for employment in non-isothermal bioreactors.
