摘要:
In a method for producing an L-amino acid or a nucleic acid by culturing a microorganism having an ability to produce the L-amino acid or nucleic acid in a liquid medium contained in a fermentation tank provided with a stirring impeller with optionally adding seed crystals to the medium as required to produce and accumulate crystals of the L-amino acid or nucleic acid in the medium, and collecting crystals of the L-amino acid or nucleic acid from culture, power density of the stirring impeller is controlled to be 2.4 kW/m 3 or lower after precipitation of the crystals or addition of the seed crystals.
