Enzymaticactivity, reusability, and stability of immobilized cellulaseon modified mesoporous material with hexagonal mesostructured and different particle size (micro size and nano size) was studied. Cellulase is a group of enzymesthathydrolyzecelluloseintoglucose.Mesoporousmaterialswere first modified with various concentrations of VTMS (Vinyltrimethoxysilane). Various characterizations were conducted by using Transmission Electron Microscopy (TEM), nitrogen sorption and Fourier Transform Infrared Spectrometry (FTIR). Our study showed that the amount of VTMS affected the activity of immobilized cellulase enzymes. The research results suggest that hexagonal structure mesoporous silica material is promising as support for enzyme immobilization. © 2006-2016 Asian Research Publishing Network (ARPN).
