Publication number: 20130040350Abstract: A dense but oxygen permeable membrane separates the oxygen supply compartment from the fermentation compartment, which contains all microorganisms, a nutrient medium and the pretreated lignocellulose.

These nucleotide sequences are each operably linked to the same or a different promoter. Recombinant bacteria capable of metabolizing sucrose to produce glycerol and/or glycerol-derived products such as 1,3-propanediol and 3-hydroxypropionic acid are also described.Type: GrantFiled: December 6, 2010Date of Patent: March 6, 2012Assignee: E.I. du Pont de Nemours and CompanyInventor: Tina K. Van Dyk

Patent number: 8129157Abstract: The invention relates to the development of appropriate cultivation conditions for a bacteria to grow anaerobically (fermentatively) on a glycerol substrate. The method requires culturing bacteria having a functional 1,2-propanediol pathway and a functional type II glycerol dehydrogenase-dihydroxyacetone kinase pathway in a culture medium containing high concentrations of glycerol, a neutral to mildly acidic pH, low levels of potassium and phosphate, and high levels of CO2, such that glycerol is thus converted into a desirable product, such as ethanol, hydrogen, formate, succinate, or 1,2-propanediol.Type: GrantFiled: March 30, 2007Date of Patent: March 6, 2012Assignee: William Marsh Rice UniversityInventor: Ramon Gonzalez

Publication number: 20120052536Abstract: Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, methods are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials, to produce an intermediate or product, e.g., by fermentation.Type: ApplicationFiled: July 15, 2011Publication date: March 1, 2012Applicant: XYLECO, INC.Inventors: Marshall MEDOFF, Thomas Craig MASTERMAN, Seul-a BAE, Kelly WALLICK

Patent number: 8119378Abstract: The invention relates to the production of alcohols by microbial fermentation, particularly to production of alcohols by microbial fermentation of substrates comprising CO. It more particularly relates to processes for the production of alcohols from their corresponding acids in the presence of a substrate comprising CO. In particular embodiments, a fermentation reaction producing acid(s) and optionally alcohol(s) is perturbed such that at least a portion one or more of acid(s) is converted to alcohol.Type: GrantFiled: February 18, 2009Date of Patent: February 21, 2012Assignee: LanzaTech New Zealand LimitedInventors: Sean Dennis Simpson, Christophe Collet, Phuong Loan Tran, Bakir Al-Sinawi, Richard Llewellyn Sydney Forster, Matthew James Rowe, Gary Chan, Kelly Marie Mahar, Jennifer Mon Yee Fung

Publication number: 20120034648Abstract: The invention relates to a cell which comprises a nucleotide sequence encoding a xylose isomerase, wherein the amino acid sequence of the xylose isomerase has at least about 70% sequence identity to the amino acid sequence set out in SEQ ID NO: 3 and wherein the nucleotide sequence is heterologous to the host. A cell of the invention may be used in a process for producing a fermentation product, such as ethanol. Such a process may comprise fermenting a medium containing a source of xylose with a cell of the invention such that the cell ferments xylose to the fermentation product.Type: ApplicationFiled: March 5, 2009Publication date: February 9, 2012Inventors: Paul Klaassen, Jan Metske Van Der Laan, Bianca Elisabeth Maria Gielesen, Gijsberdina Pieternella Van Suylekom
