Glucan conversion in enzymatic saccharification of pretreated Norway spruce with A varying WIS and B varying enzyme preparation loading. Glucan conversion after 72 h of enzymatic saccharification was calculated according to Eq. (2) with a glucan content of 48.3% of pretreated solids. The values shown are averages of nine measurements (triplicate reactions and triplicate analyses of each reaction). Asterisks indicate significant differences (Student's t-test) between reactions with air and N2: ***p ≤ 0.01; **0.01 < p ≤ 0.05; * 0.05 < p ≤ 0.1
