Immobilized lipases and their applications
, 2008 Lipases are able to catalyse the hydrolysis of glyceridic esters in aqueous media and the synthesis of esters in non-aqueous media. They are thus able to catalyse numerous reactions of industrial interest. Whether it is by inclusion, by adsorption or by covalent link, the immobilisation of lipases aims at conferring them a good stability that enables a
