Organic acids are prepared from their salts electrodialytically. At the same time, another acid is converted electrodialytically into the corresponding salt. Both electrodialytic conversions take place in the same electrodialysis unit. If the salt of the organic acid has been fermentatively prepared as, for example, malate from fumarate, it is possible both to prepare malic acid by electrodialysis and also to prepare fumarate from fumaric acid for the fermentation. Through coupling substrate and product streams in the electrodialysis, a closed circuit is formed.
