Using creativity and unconventional ideas, researchers and engineers at Evonik, one of the world leaders in specialty chemicals, have achieved a significant breakthrough in the biotechnological production of amino acids based on fermentation. They integrated the separating methods of chromatography and reverse osmosis and an online analytical method based on spectroscopy—all of which tend to be used in other industry sectors—in a biotechnological process. This created an outcome experts had previously considered nearly impossible. The researchers’ objective was to achieve optimal separation of the desired amino acid from a fermentation broth.
