Enzymatic glucose and xylose release from pretreated solid fractions. Response surface modeling of enzymatic glucose release from wheat straw pretreated at (a) acidic and (b) alkaline conditions, and enzymatic xylose release from wheat straw pretreated at (c) acidic and (d) alkaline conditions. Temperature is in°C and monosaccharide releases in g/kg original dry matter. All samples were pretreated for 10 min.
