  1. 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
  2. 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
