  • Patent number: 10072278
    Abstract: The present invention relates to a novel L-valine-producing strain which is transformed so as to strengthen the expression of L-valine operon by having a nucleotide sequence, for coding a leader peptide in a regulatory region of ilvBN operon, entirely deleted, or partially deleted or substituted. In addition, the present invention relates to a method for producing L-valine using the novel L-valine-producing strain. According to the novel valine-producing strain and the L-valine production method of the present invention using the strain, there is an advantageous effect of producing L-valine at high efficiency and high yield.
