  • Patent number: 11154607
    Abstract: The disclosed compositions and methods provide an approach for the rational development of a nucleic acid vaccine. Methods are disclosed to deliver a viral genome, and/or a representative or derivative of such, that is attenuated but can, when co-delivered with unreplicable compensatory translational tools to a host cell, initially generate phenotypically wild-type, genetically attenuated viruses which infect subsequent cells and elicit a relevant and robust immune response. However, progeny of this initial generation, lacking the compensatory tools delivered to the initial host cells, are both phenotypically and genetically attenuated, thereby compromised in their ability to induce disease.

  • Patent number: 9279137
    Abstract: A mutant bacterial acetolactate synthase (AHAS I) which is resistant to feedback inhibition by L-valine is described. Also described is a method for producing branched-chain L-amino acids using a bacterium from the Enterobacteriaceae family wherein the L-amino acid productivity of said bacterium is enhanced by the use of the acetolactate synthase (AHAS I) which is resistant to feedback inhibition by L-valine. This acetolactate synthase contains a mutant small subunit encoded by the mutant ilvN gene.

  • Patent number: 9150885
    Abstract: A method of producing isopropyl alcohol includes: culturing an isopropyl alcohol-producing Escherichia coli under a bacterial cell growth condition in which the Escherichia coli stably proliferates in an isopropyl alcohol production period while continuously supplying a substrate solution to a culture tank and continuously removing a product-containing culture solution from the culture tank, the substrate solution containing a plant-derived raw material, the number of cells of the isopropyl alcohol-producing Escherichia coli in the culture tank being maintained during the culturing, and the isopropyl alcohol-producing Escherichia coli having isopropyl alcohol production ability introduced or modified by genetic recombination; bringing the isopropyl-alcohol-producing Escherichia coli into contact with the plant-derived raw material in the culture tank to produce isopropyl alcohol; and recovering the isopropyl alcohol produced by the isopropyl alcohol-producing Escherichia coli from the culture solution that co

  • Patent number: 9115382
    Abstract: A reagent is provided for the detection of an exotoxin protein produced by a beta-hemolytic streptococcus bacteria suspected of being present in a host biological fluid collected from a subject. An enzyme inhibitor is present to inhibit rogue protein modification of the substrate to prevent a false positive result of the color change. A kit is provided that is readily usable by an untrained user and merely requires that an element of the kit be contacted with a biological sample and thereafter no further actions are required by the user before a discernable color change is observed with visible or UV light and a positive/negative results reference card.

  • Patent number: 9080178
    Abstract: The invention provides transgenic Escherichia coli cells comprising a mutation in cydAB gene, and/or cyoABCD gene, and/or cbdAB gene, and/or ygiN gene, wherein the mutation reduces (preferably, but not necessarily, by 100%) the cytochrome oxydase activity of a protein encoded by cydAB gene, and/or cyoABCD gene, and/or cbdAB gene, and/or ygiN gene. In a preferred embodiment, the mutation is a deletion of the cydAB gene, cyoABCD gene, and cbdAB gene. In another embodiment, the mutation is a deletion of the cydAB gene, cyoABCD gene, cbdAB gene, and ygiN gene.

  • Publication number: 20150147794
    Abstract: Disclosed herein is a microorganism capable of producing ethane-1,2-diol from D-xylose, and a method for producing ethane-1,2-diol using the same. More specifically, the present invention relates to an engineered Escherichia coli (E. coli) prepared by knocking out a D-xylose isomerase gene and/or an aldehyde dehydrogenase gene within the genomic DNA of E. coli and transforming an expression vector including a D-xylose dehydrogenase gene into the E. coli, and an efficient method for producing ethane-1,2-diol from D-xylose using the engineered E. coli.

  • Publication number: 20150148293
    Abstract: Mutant fibroblast growth factor (FGF) proteins having a polypeptide sequence with a high sequence identity to proteins encoded by members of the Fgf-1 subfamily of genes from a mammalian species, such as human, and with a specific amino acid substitution of an alanine at a position corresponding to amino acid position 66 of human FGF-1 with a cysteine and/or a specific amino acid substitution of a phenylalanine at a position corresponding to amino acid position 132 of human FGF-1 with a tryptophan (based on the 140 amino acid numbering scheme of human FGF-1) are provided. Other amino acid mutations or substitutions may be combined. Polynucleotide sequences encoding the mutant FGF proteins and host cells containing such polynucleotide sequences are provided. Methods of administering a mutant FGF protein to an individual to treat an ischemic condition or disease or a wound or tissue injury are also provided.

    Abstract: The present invention relates to microorganisms of Escherichia coli having enhanced L-tryptophan productivity and to a method for producing L-tryptophan using the same. More particularly, the present invention relates to an Escherichia coli variant in which repression and attenuation control of the tryptophan operon is released and accumulation of anthranilate is reduced and thereby enhancing L-tryptophan productivity. The present invention also relates to a method for producing L-tryptophan using the Escherichia coli variant.
