Abstract
Animal product free (APF) media and processes for the culture and fermentation of botulinum toxin producing Clostridium botulinum bacteria. The botulinum toxin obtained can be used for formulating and compounding botulinum toxin pharmaceutical compositions. The APF media can contain significantly reduced levels of meat or dairy by-products and use non-animal based products instead of the animal-derived products. Preferably, the APF media used are substantially free or free of animal derived products.
