Patent ID: 8771981

Claim:
A method for producing an L-amino acid, which comprises: (a) preparing a processed product of a microalga, which promotes production and accumulation of the L-amino acid by a bacterium having an ability to produce the L-amino acid, comprising: (i) culturing the microalga in a first medium, followed by (ii) incubating the cultured microalga of step (i) at a mid-temperature of 40° C. to 70° C., and (iii) performing centrifugation on the product of step (ii), resulting in a precipitate and supernatant; and (b) culturing the bacterium in a second medium comprising the supernatant of step (iii) to produce and accumulate the L-amino acid in the second medium, wherein the supernatant comprises glucose or glycerol; and (c) collecting the L-amino acid from the second medium.
