一般描述

2,3,5-三苯基氯化四氮唑(TTC)是一种广泛用于固体培养基中微生物菌落计数的染料。这种染料在氧化形式下是无色的,当被微生物还原时,由于形成了甲臜,因此变为红色。活的微生物,例如大肠杆菌和其他大肠菌群,通过酶促作用减少TTC,形成红色的甲臜,保留在细胞的颗粒内部。强烈建议在检测巴氏杀菌奶时使用TTC,因为在巴氏杀菌奶中有很大比例的微生物无法减少 TTC,而这些微生物无法通过实验室程序检测到。较高浓度的 TTC 可对革兰氏阳性菌的生长起抑制作用。

应用

2,3,5-三苯基氯化四氮唑(TTC)溶液是一种氧化还原指示剂,可以帮助指示细胞呼吸、识别活细胞和非活细胞,以及识别能够在固体培养基上还原 TTC 的微生物
