    Abstract: The invention relates, in general, to methods of processing lignocellulosic biomass to fermentable sugars and to methods that rely on hydrothermal pretreatment. Xylose monomer yields comparable to those achieved using two-stage pretreatments can be achieved from soft lignocellulosic biomass feedstocks by pretreating to very low severity in a single-stage pressurized hydrothermal pretreatment, followed by enzymatic hydrolysis to release xylose retained in the solid state. In some embodiments, pretreated biomass is separated into a solid fraction and a liquid fraction, the solid fraction subject to enzymatic hydrolysis, and the separated liquid fraction subsequently mixed with the hydrolysed solid fraction.
