  • METHOD OF PRODUCING ISOPRENOID COMPOUND
    Publication number: 20210403954
    Abstract: Producing an isoprenoid compound by: 1) culturing an isoprenoid compound-forming microorganism in the presence of a growth promoting agent at a sufficient concentration to grow the isoprenoid compound-forming microorganism; 2) decreasing a concentration of the growth promoting agent to induce formation of the isoprenoid compound by the isoprenoid compound-forming microorganism; and 3) culturing the isoprenoid compound-forming microorganism to form the isoprenoid compound, is characterized in that the growth phase of the isoprenoid compound-forming microorganism is separated from the formation phase of the isoprenoid compound.

  • Method for producing a lower alkyl ester of ?-L-aspartyl-L-phenylalanine
    Patent number: 7935506
    Abstract: A method for producing lower alkyl ester of ?-L-aspartyl-L-phenylalanine by cultivating a recombinant Escherichia coli bacterium that has the ability to produce and accumulate an aromatic L-amino acid according in a culture medium to produce and accumulate L-phenylalanine in the medium and synthesizing lower alkyl ester of ?-L-aspartyl-L-phenylalanine from the aspartic acid or its derivative and the obtained L-phenylalanine.

  • bacteria transformed with the yddG gene to enhance L-amino acid producing activity
    Patent number: 7666655
    Abstract: The present invention relates to a method for producing L-amino acid, such as L-phenylalanine and L-tryptophan, is provided using bacterium belonging to the genus Escherichia wherein the L-amino acid productivity of said bacterium is enhanced by enhancing an activity of protein encoded by the yddG gene from Escherichia coli, wherein said protein has an activity to make said bacterium resistant to L-phenylalanine, a phenylalanine analogue, or a tryptophan analogue. The present invention further relates to a method for producing lower alkyl ester of ?-L-aspartyl-L-phenylalanine.
