ABSTRACT:
A composition containing 1,4-dihydroxy-2-naphthoic acid at a high concentration is obtained by intracellularly and extracellularly producing 1,4-dihydroxy-2-naphthoic acid using a bacterium belonging to the genusPropionibacteriumand collecting it. This composition is efficacious in improving intestinal flora, alleviating abdominal ailments in association with the intake of milk, and preventing metabolic bone diseases.
