Effect of lignin on xylan hydrolysis at 40 °C (left column) and 50 °C (right column). Hydrolysis of xylan (1% w/V) by xylanases a, b TrXyn1, c, d TrXyn2, e, f Xyl40 and g, h Xyl40-CD in 50 mM Na-citrate buffer, pH 5. (■) Xylan hydrolysed as such, () xylan supplemented with 1% w/V enzymatic hydrolysis residue (EnzHR) lignin from steam pretreated spruce and (▲) xylan supplemented with a buffer soluble fraction of the same lignin. The hydrolysis was followed for 48 h at 40 °C and for 3 h or 24 h at 50 °C
