Characterisation of Bp-XylX-1, Bp-XylX-2, and Lr-XylC β-xylosidase enzymatic activity. The optimum (A) pH and (B) temperature of recombinant β-xylosidases were determined using pNP-Xyl (2 mM final concentration) in different buffers and temperatures. (C) The enzymatic activity of recombinant β-xylosidases was determined on artificial substrates at 2 mM final concentration. (D) Assessment of endolytic activity was performed with K-Xly 6-pNP (2 mM final concentration) where a commercial xylanase was used as control.
