Adsorption of lipopeptide and CEL on DA-GJGs with different lignin contents. a The adsorption of lipopeptide and CEL on DA-GJG and DA-GJG-DLs was measured by Bradford protein assay kit [45]. b Displayed the effect of lipopeptide on the hydrolysis and CEL adsorption onto DA-GJG and DA-GJG-DLs. Columns and lines indicated FPA in the supernatant and glucose yield, respectively. “Control” represented the system containing only substrate and enzyme. “Lipopeptide” represented the system containing lipopeptide, substrate and enzyme
