The influence of ammonium acetate on the enterotoxin production and sporulation of Clostridium perfringens (NCTC 8238 and 8798) has been studied. 1) The enterotoxin production and sporulation in the sporulation medium (with 0.4% soluble starch) were promoted by the addition of ammonium acetate. The optimum concentration of added ammonium acetate was 0.3% in NCTC 8238 and 0.1% in NCTC 8798. 2) The effect of ammonium acetate on the enterotoxin production in NCTC 8238 was enhanced by the addition of 0.01 - 0.05% glucose into the sporulation medium. The effect of ammonium acetate in NCTC 8798 was enhanced by the addition of 0.6 - 1.8% glycerol instead of glucose.ウェルシュ菌(NCTC 8238, 8798)のエンテロトキシン(ET)産生および胞子形成におよぼす酢酸アンモニウム(AAC)添加の影響を検討した. 1) 胞子形成培地(可溶性デンプン0.4%含有)にAACを添加した場合,NCTC 8238では0.3%, NCTC 8798では0.1%の添加によって,ET産生および胞子形成が上昇した. 2) NCTC 8238の場合には,胞子形成培地にグルコース(0.01-0.05%)を添加することにより,またNCTC 8798の場合にはグリセリン(0.6-1.8%)を添加することによりAACのET産生効果が著しく上昇した.
