Résumé

The aim of this study was to optimize the laccase immobilization on a silica/chitosan composite support. The innovative method proposed is based on the use of Ca(II) as a linker of the support precursors. In addition for the laccase immobilization the glycosidic part of enzyme is oxidized by periodate in order to form aldehydes reactive towards the NH
