Abstract
A method for producing an L-amino acid such as L-lysine is provided. An L-amino acid is produced by culturing a bacterium having an L-amino acid-producing ability, which has been modified so that the activity of a carotenoid biosynthesis enzyme is increased, in a medium, and collecting the L-amino acid from the medium.
Claims33
A method for producing an L-amino acid, the method comprising:
- culturing a bacterium having an L-amino acid-producing ability in a medium to accumulate an L-amino acid in the medium;
- and
- collecting the L-amino acid from the medium,
- wherein the bacterium has been modified so that the activity of a carotenoid biosynthesis enzyme is increased as compared with a non-modified bacterium.
1 more element
A method for producing bacterial cells containing a carotenoid, the method comprising:
- culturing a bacterium that is able to produce an L-amino acid and a carotenoid in a medium to accumulate a carotenoid in cells of the bacterium;
- and
- collecting the cells,
- wherein the bacterium has been modified so that the activity of a carotenoid biosynthesis enzyme is increased as compared with a non-modified bacterium.
1 more element
Cells of a bacterium,
- wherein the cells contain a carotenoid,
- wherein the bacterium is able to produce an L-amino acid and a carotenoid, and
- wherein the bacterium has been modified so that the activity of a carotenoid biosynthesis enzyme is increased as compared with a non-modified bacterium.
