    摘要: A microorganism is provided which has an ability to produce an L-amino acid such as L-lysine, L-tryptophan, L-phenylalanine, L-valine, L-leucine, L-isoleucine and L-serine, and has been modified to increase the activity of pyruvate synthase or pyruvate:NADP+ oxidoreductase. This microorganism is cultured in a medium containing ethanol or an aliphatic acid as the carbon source to produce and accumulate the L-amino acid in the medium or cells, and the L-amino acid is collected from the medium or the cells.

    摘要: An organic acid is produced by allowing a bacterium which has an ability to produce an organic acid and has been modified so that expression of yidE gene is enhanced, or a product obtained by processing the bacterium, to act on an organic raw material in a reaction mixture containing carbonate ions, bicarbonate ions, or carbon dioxide gas to produce the organic acid, and collecting the organic acid.

    摘要: In a method for producing a target substance utilizing a microorganism, which comprises culturing a γ-proteobacterium in a medium to produce and accumulate the target substance in the medium or cells and collecting the target substance, there is used a strain in which the ArcA protein does not normally function in the cell by means of, for example, disruption of the arcA gene on the chromosome.

    摘要: A microorganism which can metabolize a carbon source at a specific pH in a liquid medium containing L-glutamic acid at a saturation concentration and the carbon source, and has ability to accumulate L-glutamic acid in an amount exceeding the amount corresponding to the saturation concentration in the liquid medium at the pH; and a method for producing L-glutamic acid by fermentation, which comprises culturing the microorganism in a liquid medium of which pH is adjusted to a pH at which L-glutamic acid is precipitated, to produce and accumulate L-glutamic acid and precipitate L-glutamic acid in the medium.
