Publication number: 20240102064Abstract: 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 pretreasting 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.Type: ApplicationFiled: November 29, 2023Publication date: March 28, 2024Applicant: Inbicon A/SInventors: Jan Larsen, Niels Nielsen Poulsen, Martin Dan Jeppesen, Kit Kellebjerg Mogensen

Patent number: 9920345Abstract: 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, ?-glucosidase, endoxylanase, and ?-xylosidase activities at activity levels in nkat/g glucan of endoglucanase of at least 1100, exoglucanase of at least 280, ?-glucosidase of at least 3000, endoxylanase of at least 1400, and ?-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.Type: GrantFiled: February 5, 2014Date of Patent: March 20, 2018Assignee: INBICON A/SInventors: Jan Larsen, Niels Nielsen Poulsen, Martin Dan Jeppesen, Kit Kellebjerg Mogensen

Publication number: 20150037856Abstract: Methods are provided for improved processing of lignocellulosic biomass. Hydrothermally pretreated lignocellulosic biomass is subject to separate hydrolysis and fermentation (SHF) or prehydrolysed and subject to simultaneous saccharification and fermentation (SSF) at high initial loadings of cellulase enzymes, at least 15 FPU/g DM. The cellulase enzymes are subsequently recycled and used in subsequent hydrolysis cycles along with a lower dose supplementation of fresh enzyme. Loss of enzyme activity between hydrolysis cycles is offset by improved overall process advantage.Type: ApplicationFiled: October 6, 2011Publication date: February 5, 2015Applicant: Inbicon A/SInventors: Jan Larsen, Martin Dan Jeppesen
