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

Table 2 Zeta potentials and average particle sizes of Avicel, LS and cellulase

Samples	Avicel	Avicel + LS	LS	LS + cellulase	Cellulase
Zeta potential (mV)	− 5.57 ± 0.42^a	− 16.34 ± 1.54^b	− 19.90 ± 1.08^c	− 37.00 ± 2.81^d	− 0.75 ± 0.18^e
Average particle size (nm)	398.78 ± 10.51^a	94.10 ± 2.55^b	87.04 ± 3.77^c	79.57 ± 2.78^d	6.28 ± 1.38^e

Avicel + LS means the complex particles of Avicel and LS in Avicel 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
