Comparative Studies on Enzymatic Activity of Porcine Pancreatic Lipase Immobilized onto Functionalized Rod-Like SBA-15 Mesoporous Materials with Aminopropyl and Glutaraldehyde

Abstract:

Rod-like SBA-15 mesoporous materials were synthesized and modified using two-step process through aminopropyl and glutaraldehyde. Aminopropyl was first covalently bonded to silanol groups present on the surface of mesoporous silica. Successively, the reaction of aldehyde with aminopropyl was followed. Immobilizations of Porcine pancreatic lipase (PPL) onto functionalized SBA-15 (NH₂-SBA-15-PPL and G-SBA-15-PPL) have been achieved. Relative activities and reusability of NH₂-SBA-15-PPL and G-SBA-15-PPL for triacetin hydrolysis have been studied.
