The present inventors have made studies on cultivation conditions suitable for the production of equol, using bacteria that are classified into the family Coriobacteriaceae and the family Streptococcaceae as one example of microorganism groups. As a result, it is found that the equol production efficiency is dramatically increased when the concentration of a hydrogen gas in a gas phase in which fermentation is to be carried out is 40-100% (particularly 100%) by mass. Namely, the present inventors succeeded in the establishment of cultivation conditions suitable for the production of equol using an anaerobic microorganism. |
