Erwin Flaschel

Title: Erwin Flaschel: Innovator in Enzyme Immobilization

Introduction

Erwin Flaschel is a notable inventor based in Chavannes, Switzerland. He has made significant contributions to the field of enzymatic catalysts, particularly through his innovative patent related to enzyme immobilization.

Latest Patents

Flaschel holds a patent for "Enzyme immobilization on mineral particles coated with chitosan." This invention involves the production of enzymatic catalysts from mineral particles that are coated with chitosan. The enzymes can be directly absorbed onto the surface after a cross-linking treatment to stabilize the coating or immobilized by chemical bonds after treatment with a bifunctional reagent, such as glutaraldehyde. The stability of the biocatalyst is enhanced by retreatment with a bifunctional reagent after enzyme immobilization. Enzymes sensitive to glutaraldehyde are fixed using a carbodiimide. The catalysts produced are insoluble in aqueous solutions, and the particles are rigid and incompressible, making them suitable for use in fixed-bed and fluidized-bed reactors. The immobilization yield can reach up to 90% depending on the conditions.
