Co-immobilization of three cellulases on Au-doped magnetic silica nanoparticles for the degradation of cellulose

Chem Commun (Camb). 2012 Jan 21;48(6):886-8. doi: 10.1039/c2cc16661e. Epub 2011 Dec 5.

Abstract

Three cystein-tagged cellulases co-immobilized on AuNP and Au-MSNP for the hydrolytic degradation of cellulose. The biochemical properties, stabilities, activities and reusability of these co-immobilized systems were compared to those of mixtures of free cellulases.
