Adsorption of Simons' stain dyes on (A) pretreated solids and on (B) glucan before and after 72 h enzymatic saccharification at 12.5% WIS with varied enzyme preparation loadings in the presence of air or N2. The analysis was conducted in triplicate and error bars show standard deviations. Asterisks indicate significant differences (Student's t-test) between reactions with air and corresponding (same enzyme loading) reactions with N2: ***p ≤ 0.01, **0.01 < p ≤ 0.05, * 0.05 < p ≤ 0.1
