Abstract
Disclosed are a medium composition for culturing Clostridium botulinum comprising a potato peptone, a yeast extract and glucose, and a method of preparing a botulinum toxin using the same. The medium excludes animal-derived products and major allergens, and enables the botulinum toxin-producing strain to reach the maximum growth level within a short time, thereby providing effects of shortening the production time and reducing the production cost in the botulinum toxin production process.
