ITQ-6, a delaminated material derived from the lamellar precursor of the Ferrierite zeolite, is an excellent support for immobilisation of enzymes; this has been proved by supporting two different enzymes, β-galactosidase from Aspergillus Oryzae and penicillin G acylase from Escherichia Coli, by electrostatic and covalent interactions, respectively; the adequacy and versatility of the ITQ-6 support and the high stability and catalytic activity of the resultant supported enzymes are shown, with ITQ-6 clearly superior to other already well optimised laboratory and industrial supports for enzymes.
