Eucalyptus lignin modification for dynamic adsorption with lignocellulose-degradation enzymes dependent on pH values

•Eucalyptus Lignin and lignin modification were used for enzymes dynamic adsorption.•The adsorption capacity of enzymes was xylanase > β-glucosidase > cellulase, and the adsorption capacity of enzyme components was EG II > CBH I.•Some adsorption behaviors of enzymes onto lignin were non-inhibitory adsorption.•Electrostatic force showed great importance in the enzyme adsorption process.•The lignin-amine for dynamic adsorption with cellulase dependent on pH values.
