MATRIX OF RICE HUSK SILICA FOR IMMOBILIZING ENZYME AND USES THEREOF

摘要

The present invention relates to a preparation method of a matrix of rice husk silica for immobilizing enzyme wherein a rice husk silica is modified with APTES((3-aminopropyl)triethoxysilane) and glutaraldehyde, a matrix of rice husk silica for immobilizing enzyme prepared by said method, a rice husk silica-enzyme complex wherein enzyme is immobilized onto said matrix of rice husk silica and a preparation method of valuable substances using said rice husk silica-enzyme complex. The rice husk silica having a nanoporous structure cannot only facilitate diffusion of substrate during enzyme reaction but also can be utilized as a path through which intermediates from the consecutive enzyme reactions can travel. Therefore, it can be effectively utilized in preparing valuable substances.
