“With our investment in the León site, we are well equipped to further strengthen our position as the global market and technology leader for fermentation-generated cystine,” said Dr. Gerhard Schmid, head of WACKER BIOSOLUTIONS, explaining the expansion measures. “The modernized fermentation plants and the new cystine production plant enable us to reliably meet our customers’ growing demand for cysteine and cystine, and to commercialize new fermentation-generated products.

Cystine and cysteine, the amino acid produced from it, are widely used in the pharmaceutical, cosmetics and food sectors not only, for example, to manufacture flavorings and make doughs in baked goods easier to process, but also as a free-radical scavenger in cosmetics products or as an expectorant in cough medicines. WACKER is the first company in the world to produce cystine by fermentation in a patented biotech process. Due to the entirely plant-based and inorganic raw materials, WACKER cystine and cysteine are purely vegetarian. This makes them especially safe for use in food and pharmaceutical products. In 2008, WACKER was awarded the Federation of German Industries (BDI) Environmental Prize for its innovative production of cysteine
