    • PROBLEM TO BE SOLVED: To provide a method for mass-producing dipicolinic acid at low cost.
      SOLUTION: The method for highly efficiently producing dipicolinic acid from a sort of most inexpensive so-called industrial wastes comprises the following steps: (1) Koji and yeast are made to act on a steamed plant material to effect fermentation, and alcohol-based volatiles are removed from the resultant plant material at normal or reduced pressures to prepare medium substrate, (2) the medium substrate is inoculated with bacillus natto to make a fermented product, and (3) from the fermented product, the objective dipicolinic acid is refined. Specifically, in this method, distillation tailings produced in e.g. manufacturing Sho-chu( low-grade distilled spirits ) are used as the medium substrate.
