Abstract

A recombinant cutinase from Fusarium solani pisi was immobilized by adsorption on several zeolites and its activity the water content and water activity. The effects of the zeolite framework composition (including cation nature) and acidity were studied. The results were compared with other commonly used supports: polyamide Accurel-PA6, silica and alumina. Both the nature of the cation and the silica: alumina (Si: Al) ration of the framework revealed to ba important parameters. The accordance with results obtained with silica and alumina.
