Abstract:Cellulase was covalently immobilized using modified mesoporous silica as carrier, and the characters of immobilized cellulase were investigated including the optimum pH, the optimum temperature, thermal stability, reusability, storage stability and enzyme kinetics. As compared to the free enzyme, the optimum pH of the immobilized cellulase showed no changes, the optimum temperature showed a slight increase to 60°C. The immobilized enzymes demonstrated enhanced thermal stability, while the free enzymes lost alm… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
