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 subjected to enzymatic hydrolysis, and the separated liquid fraction subsequently mixed with the hydrolysed solid fraction.

Abstract: 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.

Abstract: A range of concentrations exists in which fermentation inhibitors derived from pretreatment of lignocellulosic feed stocks inhibit growth of lactic acid bacteria without affecting fermentive yeast. By optimizing levels of fermentation inhibitors to fall within this range, yeast fermentations of lignocellulosic biomass can be conducted under non-sterile conditions with ethanol yields comparable to those achieved under sterile conditions. Optimised inhibitor levels can be achieved by controlling the water/biomass ratio of a lignocellulosic biomass during and after pretreatment, for example by washing the fiber fraction of a previously pretreated lignocellulosic biomass with a pre-defined amount of fresh water or recycled process solutions. Crude extracts of liquid fraction or process solutions from pretreatment of lignocellulosic biomass can also provide an effective anti-baterial treatment for first generation starch fermentations.
