It all began back in the early 1970s when Novo Industri established a production facility in Kalundborg. Now, 50 years later, new companies are again establishing fermentation plants in the area. Fermentation with natural or genetically engineered bacteria and yeast is fundamental to a broad range of industrial activities in Kalundborg ranging from the large industrial-scale production of enzymes, protein feed, food and pharmaceuticals to the small-scale wine production on the Røsnæs peninsula.
