| 摘要 |
It is intended to provide an industrial purification method for PDC obtained by fermentative production. A purification method for 2-pyrone-4,6-dicarboxylic acid, characterized by allowing a monovalent to tetravalent cationic salt to exist in a fermentation liquid containing 2-pyrone-4,6-dicarboxylic acid produced by a microorganism; and a purification method for 2-pyrone-4,6-dicarboxylic acid, characterized by extracting 2-pyrone-4,6-dicarboxylic acid from a fermentation liquid containing 2-pyrone-4,6-dicarboxylic acid produced by a microorganism without forming a 2-pyrone-4,6-dicarboxylate. |
