DSM has a well-known portfolio of biopreservative products, marketed under the "Delvo" range, for a number of applications, including beverage, meat, cheese, and baked goods. The active ingredient to extend shelf life and prevent spoilage is natamycin, an antifungal derived from Streptomyces natalensis. The company uses a controlled fermentation route to produce natamycin. Recognizing the potential of natamycin as a preservation tool in different segments of the agrifood value chain, in 2012 the company launched Zivion M for the suppression of mushroom dry bubble disease caused by Verticillium fungicola. Later, the company explored the use of natamycin for post-harvest control for fruits, which requires the right formulation and dosage for success.
