Abstract
The continuous production of Clostridium tetani toxin has been carried out in a 1-liter stirred culture vessel for as long as 65 days. Toxin production of approximately 120 flocculating units per ml was maintained with a dilution rate of 0.125 hr(-1), a temperature of 34 C, a pH of 7.4, and the addition to the medium of 0.1 g of potassium chloride per liter. The average minimal lethal intraperitoneal dose of the toxin in mice was approximately 10(6) per ml.
摘要
破伤风梭菌毒素的连续生产已在1升搅拌培养容器中持续进行了长达65天。在稀释率为0.125小时^(-1)、温度为34℃、pH值为7.4且每升培养基添加0.1克氯化钾的条件下，维持了约每毫升120个絮凝单位的毒素产量。该毒素对小鼠的平均最小腹腔致死剂量约为每毫升10^6。

Nitrogen-gas bubbling during the cultivation of Clostridium tetani produces a higher yield of tetanus toxin for the preparation of its toxoid.在破伤风梭菌培养过程中通入氮气气泡可提高破伤风毒素的产量，用于制备类毒素。

Effective levels of tetanus toxin can be made in a production medium totally lacking both animal (e.g., brain heart infusion) and dairy proteins or digests (e.g., casein hydrolysates).破伤风毒素的有效产量可以在完全不含动物蛋白（如脑心浸液）和乳蛋白或消化物（如酪蛋白水解物）的生产培养基中实现。
