The present study was to redesign the conventional Mueller and Miller medium to produce tetanus toxin from Clostridium tetani. Meat based ingredients (such as Bovine Heart/ Brain/ Liver Infusion) were replaced with vegetable peptone & alternate casein hydrolysate and scaled up from 100mL to 1000mL. Modified Mueller and Miller Medium containing vegetable peptone (substitute of BHI) and alternate casein hydrolysate were used for production and scale -up of tetanus toxin. Detoxification of tetanus toxin was carried out by using formaldehyde to produce tetanus toxoid. Purification of tetanus toxoid was achieved by fractional precipitation. It was found that under optimum conditions, use of meat free media leads to production of tetanus toxin with equal limes flocculation (Lf) titer and high antigenic content at par with conventional meat based media without any post vaccination infections. The yield of toxin was improved during scale-up of the process. The present study provides a method for growth of Clostridium tetani that maximizes tetanus toxin production without any use of animal-derived components.
