FIG 4 .

Comparative degradation of wheat straw by the various complexes and free enzyme systems after 24 h. The composition of the complexes and free enzyme systems is indicated in symbolic form. Orange bars represent the combination of the three xylanases (Xyn10B plus Xyn11A plus Xyn10A), and dark blue bars represent the combination of the four xylanases (Xyn10B plus Xyn11A plus Xyn10A plus Xyl43A). Enzymatic activity is defined as µM total reducing sugars. Each reaction was performed in triplicate, and standard deviations for straw hydrolysis are indicated.
