Method for Producing an L-Amino Acid

摘要

A method for producing an L-amino acid by preparing a processed product of a microalgae, which promotes production and accumulation of the L-amino acid by a bacterium having an ability to produce the L-amino acid, by culturing the microalgae in a medium, and processing the resulting culture at a midtemperature; culturing the bacterium in a medium containing the processed product of the microalgae to produce and accumulate the L-amino acid in culture; and collecting the L-amino acid from the culture.

主权项

1. A method for producing an L-amino acid, which comprises:
(a) preparing a processed product of a microalga, which comprises a fatty acid and promotes production and accumulation of the L-amino acid by a bacterium having an ability to produce the L-amino acid, by culturing the microalga in a first medium, followed by processing at a mid-temperature of 40° C. to 70° C., (b) culturing the bacterium in a second medium comprising the processed product of the microalga to produce and accumulate the L-amino acid in the second medium, and (c) collecting the L-amino acid from the second medium.
