摘要： The invention relates to a method of processing lignocellulosic biomass comprising: providing lignocellulosic biomass feedstock; pretreating said biomass feedstock by continuous hydrothermal pretreatment in a pressurized reactor; measuring xylan number or lignin number in the output stream of pretreated biomass from the pretreatment reactor; and controlling the pretreatment reactor so as to maintain, in the output stream of pretreated biomass, a pre-determined level of measured xylan number or lignin number. The method allows for continuously controlling the digestibility of a lignocellulosic biomass during the step of pretreatment, and accordingly provides a continuous estimate of the severity of the pretreatment.

摘要： 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.

摘要： Methods of processing lignocellulosic biomass to fermentable sugars are provided which rely on hydrothermal pretreatment. Soft lignocellulosic biomass feedstock is pretreated in a single-stage pressurized hydrothermal pretreatment to very low severity. The pre-treated biomass is hydrolysed, typically as a whole slurry, using enzymatic hydrolysis catalysed by an enzyme mixture comprising endoglucanase, exoglucanase, β-glucosidase, endoxylanase, and β-xylosidase activities at activity levels in nkat/g glucan of endoglucanase of at least 1100, exoglucanase of at least 280, β-glucosidase of at least 3000, endoxylanase of at least 1400, and β-xylosidase of at least 75, so as to produce a hydrolysate in which the yield of C5 monomers is at least 55% of the original xylose and arabinose content of the feedstock prior to pretreatment.
