Figure 4

Xylanase-depleted wheat straw (Dpl-WS) screening of site-saturation libraries. Filled squares and open circles correspond to site-saturation mutagenesis (SSM) performed at positions 3 and 111, respectively. The 288 clones of each library are positioned on the x-axis, and their activity on Dpl-WS is shown on the y-axis. The two solid lines represent the mean value (μ) and the value of μ + 4σ for the activity of Thermobacillus xylanilyticus xylanase (Tx-Xyn)-AF7.
