Effects of lipopeptide on the fractions of free 45818-WT and 45818-Core. Avicel (a), holocellulose (b), lignin (c) and DA-GJG (d) were used as substrate, respectively. The pNPCase activities in the supernatant were measured and the concentration could be figured out according to the standard curve (see Additional file 7: Figue S7)
