Figure 4From: Aiming for the complete utilization of sugar-beet pulp: Examination of the effects of mild acid and hydrothermal pretreatment followed by enzymatic digestionSpecific sugar-degradation products formed after pretreatment. Light-grey bars = 120°C pretreatment, grey bars = 140°C pretreatment, dark-grey bars = 170°C pretreatments, shaded bars = pretreatments with 1% w/w sulfuric acid (on a dry = matter basis), non = shaded bars = pretreatments in water.Back to article page
