METHOD FOR PRODUCTION OF L-AMINO ACID

摘要

In a method for producing an L-amino acid by fermentation comprising culturing a microorganism having an L-amino acid-producing ability in a liquid medium to accumulate the L-amino acid in the medium with precipitation of the L-amino acid, a polymer selected from the group consisting of a water-soluble cellulose derivative, a water-soluble polyvinyl compound, a polar organic solvent-soluble polyvinyl compound, a water-soluble starch derivative, an alginic acid salt and a polyacrylic acid salt is added to the medium.
