Fig. 4From: A novel film–pore–surface diffusion model to explain the enhanced enzyme adsorption of corn stover pretreated by ultrafine grindingEquilibrium adsorption of cellulose to a SGCS and b UGCS. The equilibrium adsorption experiments were performed with different loadings of the cellulase (1.5–10.5 mg/g substrate for celluclast 1.5 L). The cellulase adsorption data were fitted by Langmuir equilibrium isotherm. Error bars represent the standard deviation of the measurements for the bound enzymeBack to article page
