An object of the present invention is to provide a method for producing an organic acid with higher fermentation efficiency. In a method for producing an organic acid from an organic raw material by allowing bacterial cells or processed products to act on the aqueous reaction liquid containing the organic raw material, the aqueous reaction liquid after the reaction is recovered, and the recovered aqueous solution is recovered. The method as described above, wherein the cells or the processed product thereof are separated from the reaction solution, and the cells or the processed product are repeatedly used by allowing the separated cells or the processed product to act on a new aqueous reaction solution.
