PROBLEM TO BE SOLVED: To provide a method for a solid bed adsorptive separation of organic acids and/or amino acids from fermentation broths containing organic acid and/or amino acids.SOLUTION: A method for separation of organic acids from fermentation broths comprises: i) providing a feed material comprising a fermentation product further comprising an organic acid; ii) providing an ion exchange adsorbent medium; and iii) separating the organic acid from the feed material by eluting the feed material with a mobile phase through the ion exchange adsorbent media. Interaction is present between the organic acid and the ion exchange adsorbent medium. The mobile phase is a dilute solution of the organic acid.
