Patents by Inventor Lhing-Yew Li-D'Elia

Lhing-Yew Li-D'Elia has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8067210
    Abstract: The invention provides methods to increase the production of an amino acid from Corynebacterium species by way of the amplification of amino acid biosynthetic pathway genes in a host cell chromosome. The invention also provides novel processes for the production of an amino acid by way of the amplification of amino acid biosynthetic pathway genes in a host cell chromosome and/or by increasing promoter strength. In a preferred embodiment, the invention provides processes to increase the production of L-lysine in Corynebacterium glutamicum by way of the amplification of L-lysine biosynthetic pathway genes in a host cell chromosome. The invention also provides novel isolated nucleic acid molecules for L-lysine biosynthetic pathway genes of Corynebacterium glutamicum.
    Type: Grant

  • Patent number: 7741460
    Abstract: The invention provides methods to increase the production of an amino acid from Corynebacterium species by way of the amplification of amino acid biosynthetic pathway genes in a host cell chromosome. Amplification may be by integration of one or more copies of a gene or genes into a host cell chromosome. One gene that may be incorporated is the gene ORF2, which encodes an unnamed hypothetical protein and which may be obtained from Corynebacterium glutamicum. The invention also provides novel isolated nucleic acid molecules for L-lysine biosynthetic pathway genes of Corynebacterium glutamicum.
