    • 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 a casein hydrolysate and 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, casein hydrolysates and minerals, is used for culture of Clostridium botulinum , the growth rate of the bacterium in the medium is higher than that in each of the medium that is in current use and the medium comprising plant-derived peptones alone. In addition, when the medium of the present invention is used, a high concentration of botulinum toxin can be produced by culturing the bacterium in a safe manner.

    • The present disclosure relates to a stable liquid composition comprising a botulinum toxin as an active ingredient which is ready-to-use without the need for a reconstitution process, and particularly, to a liquid composition capable of preventing the botulinum toxin from aggregating even when the botulinum toxin is contained at a low concentration to thereby exhibit high stability, and efficiently preventing adsorption, etc., to a container, to constantly maintain an activity of the botulinum toxin for each batch or for each liquid vial. Specifically, the present disclosure relates to the liquid composition comprising (i) a botulinum toxin as an active ingredient, (ii) L-alanine or methyl cellulose, (iii) a non-ionic surfactant, and (iv) a buffer, and optionally, an isotonic agent. The liquid composition of the botulinum toxin according to the present disclosure is which is ready-to-use without performing a reconstitution process, and thus, it is possible to improve user's convenience, and reduce a deviation of botulinum toxin activity, etc., due to dilution errors in the reconstitution process, etc. Further, the liquid composition according to the present disclosure efficiently prevents the botulinum toxin from aggregating even at a low botulinum toxin concentration to thereby have extremely excellent storage stability, and efficiently prevents adsorption of the botulinum toxin to a container, thereby constantly maintaining an activity of the botulinum toxin for each batch or for each liquid vial.

    • 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.

    • The present invention relates to a method for production of a botulinum toxin, and more particularly to a method for preparation of botulinum toxin, the method comprising the steps of: (a) treating a culture of a botulinum toxin-producing strain with acid to precipitate a botulinum toxin; (b) adding buffer to the precipitated botulinum toxin, followed by treatment with a protease inhibitor and nuclease, thereby extracting the botulinum toxin; (c) treating the extracted botulinum toxin with acid to precipitate the botulinum toxin and dissolving the precipitate in buffer; and (d) purifying the botulinum toxin by anion exchange chromatography. The use of the method of the invention toxin makes it possible to produce a high-purity botulinum toxin by a simple process, suggesting that the method is very economical and efficient. The botulinum toxin produced by the method of the invention has high purity compared to botulinum toxins produced by conventional methods, and thus has an increased ability to act in a local area. Thus, the systemic circulation of the botulinum toxin, which can result in side effects, is reduced to increase the safety. Accordingly, the botulinum toxin of the invention can be used for various purposes, including treatment of neuromuscular disorders, removal of wrinkles, and treatment of spastic hemiplegia and cerebral palsy.
