Abstract: The present invention relates to a medium composition for production of botulinum toxin and, more particularly, to a medium composition for culture of Clostridium sp. capable of producing botulinum toxin. The medium composition of the present invention comprises at least one plant-derived peptone selected from the group consisting of a garden pea hydrolysate, a cotton seed hydrolysate and a wheat gluten hydrolysate. When the medium according to the present invention, which contains plant-derived peptones and minerals, is used for culture of Clostridium botulinum, the growth rate of the bacterium in the medium is about 1.5-2 times higher than that in the medium that is in current use. In addition, when botulinum toxin is produced by culturing the bacterium in the medium, infection with transmissible spongiform encephalopathy (TSE) or the like can be prevented by blocking introduction of animal-derived components.

Abstract: A method of making botulinum toxin comprises treating a culture of a botulinum toxin-producing strain with acid to precipitate a botulinum toxin; adding buffer to the precipitated botulinum toxin, followed by treatment with a protease inhibitor and nuclease, thereby extracting the botulinum toxin; treating the extracted botulinum toxin with acid to precipitate the botulinum toxin and dissolving the precipitate in buffer; and purifying the botulinum toxin by anion exchange chromatography. The use of the method makes it possible to produce a high-purity botulinum toxin by a simple process. The botulinum toxin produced by the method has high purity, and thus has an increased ability to act in a local area. Thus, the systemic circulation of the botulinum toxin is reduced to increase the safety. Accordingly, the botulinum toxin can be used for treatment of neuromuscular disorders, removal of wrinkles, and treatment of spastic hemiplegia and cerebral palsy.
