use of soy hydrolysate for tetanus toxin production

The present work was planned to develop a modified system for the growth of C. tetani and production of tetanus toxin, the system includes growth media that contain no meat or dairy by-products using non-animal based products. Hydrolyzed soy proteins have been found to replace the meat/dairy product for growth of C. tetani and the production of its toxin, these replacements resulted in production of high tetanus toxin titer and of low side effects
