Patent number: 8481056Abstract: Whole-cell vaccines and methods for their use in producing protective immune responses in vertebrate hosts subsequently exposed to pathogenic bacteria. The present invention involves a method of enhancing antigen presentation by intracellular bacteria in a manner that improves vaccine efficacy. After identifying an enzyme that has an anti-apoptotic effect upon host cells infected by an intracellular microbe, the activity of the enzyme is reduced, thereby modifying the microbe so that it increases immunogenicity. Also, the present invention provides a method of incrementally modifying enzyme activity to produce incrementally attenuated mutants of the microbe from which an effective vaccine candidate can be selected.Type: GrantFiled: September 19, 2011Date of Patent: July 9, 2013Assignee: Vanderbilt UniversityInventors: Douglas S. Kernodle, Markian R. Bochan

Patent number: 8283150Abstract: Purified cellobiohydrolase I (glycosyl hydrolase family 7 (Cel7A)) enzymes from Penicillium funiculosum demonstrate a high level of specific performance in comparison to other Cel7 family member enzymes when formulated with purified EIcd endoglucanase from A. cellulolyticus and tested on pretreated corn stover. This result is true of the purified native enzyme, as well as recombinantly expressed enzyme, for example, that enzyme expressed in a non-native Aspergillus host. In a specific example, the specific performance of the formulation using purified recombinant Cel7A from Penicillium funiculosum expressed in A. awamori is increased by more than 200% when compared to a formulation using purified Cel7A from Trichoderma reesei.Type: GrantFiled: October 8, 2008Date of Patent: October 9, 2012Assignee: Alliance for Sustainable Energy, LLCInventors: William S.

Publication number: 20100279336Abstract: This invention provides a method for rapidly measuring an premature yeast flocculating factor of malt contained in a brewing material, comprising the following steps of: (1) mixing yeast in the late logarithmic growth phase or thereafter with a water-extracted high molecular fraction prepared from a test material sample in a buffer solution and suspending the mixture in the buffer solution; and (2) irradiating the suspension obtained in the step (1) with visible light, photographing the scattered light with a camera device, image-analyzing the image data thus obtained and determining the degree of whiteness of the suspension to measure the degree of sedimentation of the yeast in the suspension. According to the present invention, the premature yeast flocculating factor of malt contained in the brewing material can be measured in a highly accurate, rapid and simple manner, and, further, even a plurality of analytes can be rapidly measured.Type: ApplicationFiled: December 12, 2008Publication date: November 4, 2010Inventors: Setsuzo Tada, Asumi Nakahoshi

Patent number: 7420105Abstract: According to the invention, there is provided null-LOX-1 barley and plant products produced thereof, such as malt manufactured by using barley kernels defective in synthesis of the fatty acid-converting enzyme lipoxygenase-1. Said enzyme accounts for the principal activity related to conversion of linoleic acid into 9-hydroperoxy octadecadienoic acid, a lipoxygenase pathway metabolite, which—through further enzymatic or spontaneous reactions—may lead to the appearance of trans-2-nonenal. The invention enables brewers to produce a beer devoid of detectable trans-2-nonenal-specific off-flavors, even after prolonged storage of the beverage.Type: GrantFiled: March 11, 2004Date of Patent: September 2, 2008Assignee: Carlsberg A/SInventors: Klaus Breddam, Ole Olsen, Birgitte Skadhauge, Finn Lok, Soren Knudsen, Lene Molskov Bech

Patent number: 5788957Abstract: A method and apparatus for correcting refractive errors of the eye are disclosed. Accelerated reshaping of the corneal tissue is accomplished by administering one or more enzymes and/or other agents to the eye which temporarily soften the cornea. The cornea is thereafter fitted with a rigid contact lens or a series of lenses which have a concave curvature that will correct a refractive error. The softened cornea then rapidly reshapes its convex curvature to the concave curvature of the contact lens or series of lenses, thereby rendering the eye emmetropic. The enzymes and/or other agents then dissipate from the cornea, and the cornea "hardens" to retain the new emmetropic shape. After "hardening" has occurred, the lens rendering the eye emmetropic is removed.Type: GrantFiled: September 12, 1996Date of Patent: August 4, 1998Assignee: Advanced Corneal Systems, Inc.Inventor: Donald H.

Patent number: 5350681Abstract: The present invention discloses a method for the enzymatic synthesis of a peptide. A protected peptide having a C-terminal carboxylate group or a protected, N-acyl amino acid having an alpha carboxylate group is reacted with a protected peptide having an N-terminal ammonium group or a protected amino acid having an alpha ammonium group in the presence of a condensation enzyme under conditions in which the carboxylate group and the ammonium group condense to form a protected, uncharged, peptide product. This peptide product is transported across a water-immiscible hydrophobic phase into an aqueous product phase and prevented from back diffusing across the water-immiscible hydrophobic phase. The peptide product can be converted, chemically or enzymatically, to a charged species that cannot back diffuse across the water-immiscible phase into the aqueous reaction phase.Type: GrantFiled: August 12, 1992Date of Patent: September 27, 1994Assignee: The Coca-Cola CompanyInventors: Guillermo A.

Patent number: 4277505Abstract: Germination of cereal grain in malting is carried out by passing steeped grain to and through a series of six closed spaced discrete vessels in succession. The grain is maintained in each vessel for about a day and in each vessel is subjected to an upward flow of humidified attemperated air. The grain is turned either in a vessel or through transference to the next vessel. Transference from one vessel to the other is carried out by discharging the grain from each vessel along a lower conveyor to an elevator which raises the grain to an upper conveyor that discharges the grain down into the next vessel. Grain leaves the last vessel of the series as green malt and then passes to a malt kiln where it is dried to a desired moisture level.Type: GrantFiled: January 22, 1979Date of Patent: July 7, 1981Assignee: J.
