Xylooligosaccharides production from lignocellulosic biomass: Equilibrium kinetics and thermodynamic studies of endo-1,4-β-D-xylanase adsorbed onto periodic mesostructured materials

We report the adsorption equilibrium, kinetics and thermodynamic studies of endo-1,4-β-D-xylanase adsorption onto ordered mesoporous matrices of silica, carbon, and zirconia. Rapid adsorption of the enzyme was observed within 5 min, and the equilibrium was attained in 60 min. The adsorption profiles...
