ABSTRACT:
Enzymatic catalysts are produced from mineral particles coated with chitosan. The enzymes may be directly absorbed onto the surface after a cross-linking treatment to stablize the coating or immobilized by chemical bonds after a treatment with a bifunctional reagent, for example with glutaraldehyde. The stability of the biocatalyst is advantageously increased by retreatment with a bifunctional reagent after immobilization of the enzyme. Enzymes sensitive to glutaraldehyde are fixed by a carbodiimide. The catalysts thus prepared are insoluble in aqueous solutions. The particles are rigid and incompressible and are suitable for use in fixed-bed and fluidized-bed reactors. The immobilization yield may reach 90% depending on the circumstances.
