The amount of initiation protein (IP) produced by Clostridium perfringens was increased by approximately one-third by modification of Duncan-Strong sporulation medium to include 0.5% glucose, 2% proteose peptone, and 2% sodium phosphate. IP but no spores were produced by the wild type when grown at 46 degrees C and by a mutant blocked at stage 0 of sporulation. IP appears to be a vegetative cell product, perhaps an overproduced autolysin or pathogenicity factor.
通过对邓肯-斯特朗芽孢形成培养基进行改良，使其包含0.5%葡萄糖、2%蛋白胨和2%磷酸钠，产气荚膜梭菌产生的起始蛋白（IP）量增加了约三分之一。野生型在46摄氏度生长时以及在芽孢形成0阶段受阻的突变体均产生IP但不产生芽孢。IP似乎是一种营养细胞产物，可能是一种过度产生的自溶素或致病因子。
