Exploring why sodium lignosulfonate influenced enzymatic hydrolysis efficiency of cellulose from the perspective of substrate–enzyme adsorption

Table 4 Zeta potentials and average particle sizes of DA lignin, LS and cellulase

Samples	DA lignin	DA lignin + LS	LS	LS + cellulase	Cellulase
Zeta potential (mV)	− 9.94 ± 0.39^a	− 16.53 ± 0.21^b	− 19.90 ± 1.08^c	− 37.00 ± 2.81^d	− 0.75 ± 0.18^e
Average particle size (nm)	1382.92 ± 80.80^a	1030.49 ± 59.95^b	87.04 ± 3.77^c	79.57 ± 2.78^d	6.28 ± 1.38^e

DA lignin + LS means the complex particles of DA lignin and LS in DA lignin suspension after adding LS; LS + cellulase means the complex particles of LS and cellulase in LS solution after adding cellulase
Contrasting letters at superscript position within a row denote a statistically significant difference (P < 0.05). The values following ± were standard deviations. All experiments and assays were performed in triplicate
