Beschreibung
Zusammenfassung:	The present invention allows for an efficient production of a carboxylic acid, by providing a method of producing a carboxylic acid, which includes the following steps (A) and (B): (A) filtering a carboxylic acid-containing fermentation broth by passing said fermentation broth through a nanofiltration membrane, to obtain a carboxylic acid-containing filtrate from the permeate side of the membrane; and (B) extracting the carboxylic acid from the carboxylic acid-containing filtrate obtained in the step (A) using an extraction solvent which undergoes phase separation with the filtrate, and collecting a carboxylic acid extract phase-separated from the aqueous phase.
