Abstract
Methods are disclosed for increasing the level of C5 monosaccharides produced from lignocellulosic biomass using a multistage fractionation process to handle recalcitrant C5 oligosaccharides without producing unwanted degradation products. Methods for reducing C5 monosaccharides degradation products produced from lignocellulosic biomass are also disclosed. In addition, compositions and products produced by the methods are disclosed.
