Cellulosic biomass is saccharified with cellulase in the presence of a polypeptide comprising the amino acid sequence shown in SEQ ID NO: 2 or 4 and having a function of enhancing the saccharifying activity of cellulase.Type: ApplicationFiled: April 11, 2014Publication date: December 4, 2014Applicants: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Noriko SHISA, Nobuhiro ISHIDA, Chie IMAMURA, Shigeharu MORIYA, Jun KIKUCHI

Publication number: 20140356915Abstract: Processes are described for fractionating lignocellulosic biomass into cellulose, hemicellulose, and lignin, comprising fractionating lignocellulosic biomass in the presence of a solvent for lignin (such as ethanol), a hydrolysis catalyst (such as sulfur dioxide), and water, to produce a liquor containing hemicellulose, cellulose-rich solids, and lignin; hydrolyzing the hemicellulose to produce hemicellulosic monomers; saccharifying the cellulose-rich solids to produce glucose; recovering the hemicellulosic monomers and the glucose, separately or in a combined stream, as fermentable sugars; and fermenting the fermentable sugars to a fermentation product having a higher normal boiling point than water. Process integration of mass and/or energy is disclosed in many specific embodiments. The fermentation product may include an organic acid, an alcohol, a diol, or combinations thereof.Type: ApplicationFiled: May 23, 2014Publication date: December 4, 2014Applicant: API Intellectual Property Holdings, LLCInventors: Theodora RETSINA, Vesa PYLKKANEN, Ryan P.
