Patent number: 11739312Abstract: In one aspect, the invention is directed to polypeptides having an amylase and/or glucoamylase activity, polynucleotides encoding the polypeptides, and methods for making and using these polynucleotides and polypeptides. In one aspect, the polypeptides of the invention can be used as amylases, for example, alpha amylases, to catalyze the hydrolysis of polysaccharide, oligosaccharide or starch into sugars. In one aspect, the invention provides delayed release compositions comprising an desired ingredient coated by a latex polymer coating. In alternative embodiments, enzymes are used to make biofuels, e.g., ethanol, butanol, propanol, or a gasoline-ethanol mix, including a bioethanol, biopropanol, biobutanol, or a biodiesel, or for any form of fuel or biomass processing.Type: GrantFiled: December 2, 2020Date of Patent: August 29, 2023Assignees: BASF Enzymes LLC, Syngenta Participations AGInventors: Malgorzata Slupska, Geoff Hazlewood, Cathy Chang, Peter Luginbuhl, Ellen Burke, Michelle Cayouette, Uvini Gunawardena, Majid Ghassemian, Aron Silverstone, Yan Zhang

Patent number: 8614077Abstract: This invention is directed to methods for recovery of C3-C6 alcohols from dilute aqueous solutions, such as fermentation broths. Such methods provide improved volumetric productivity for the fermentation and allows recovery of the alcohol. Such methods also allow for reduced energy use in the production and drying of spent fermentation broth due to increased effective concentration of the alcohol product by the simultaneous fermentation and recovery process which increases the quantity of alcohol produced and recovered per quantity of fermentation broth dried. Thus, the invention allows for production and recovery of C3-C6 alcohols at low capital and reduced operating costs.Type: GrantFiled: November 22, 2011Date of Patent: December 24, 2013Assignee: Gevo, Inc.Inventors: William A. Evanko, Aharon M. Eyal, David A. Glassner, Fudu Miao, Aristos A. Aristidou, Kent Evans, Patrick R. Gruber, Andrew C. Hawkins, Peter Meinhold, Reid M. Renny Feldman, Uvini Gunawardena, Jun Urano

Publication number: 20110318799Abstract: There is disclosed a method of producing isobutanol. In an embodiment, the method includes providing a microorganism transformed with an isobutanol producing pathway containing at least one exogenous gene. The microorganism is selected to produce isobutanol from a carbon source at a yield of at least 10 percent theoretical. The method includes cultivating the microorganism in a culture medium containing a feedstock providing the carbon source, until isobutanol is produced. The method includes recovering the isobutanol. In one embodiment, the microorganism is a yeast with a Crabtree-negative phenotype. In another embodiment, the microorganism is a yeast microorganism with a Crabtree-positive phenotype. There is disclosed a microorganism for producing isobutanol. In an embodiment, the microorganism includes an isobutanol producing pathway containing at least one exogenous gene, and is selected to produce a recoverable quantity of isobutanol from a carbon source at a yield of at least 10 percent theoretical.Type: ApplicationFiled: September 9, 2011Publication date: December 29, 2011Applicant: GEVO, INC.Inventors: Reid M.
