一般說明

Kovac′s吲哚试剂是一种含有4-(二甲胺基)苯甲醛和盐酸的正丁醇溶液。

應用

Kovac′s吲哚试剂用于计数存储、解冻和熟肉饼等碎牛肉样本的大肠杆菌O157:H7。它还用于计数脱水黑水中的大肠杆菌

生化/生理作用

Kovac′s吲哚试剂用于检测吲哚并帮助鉴定吲哚阳性和吲哚阴性微生物。在色氨酸酶存在的情况下,大肠杆菌可以将色氨酸分解为吲哚和α丙氨酸。试剂中的p-氨基苯甲醛与吲哚发生反应,生成溶于酒精、乙醚和氯仿的樱桃红络合物。建议使用不含葡萄糖的培养基和色氨酸含量高的蛋白胨进行测试。

A simple colorimetric method for the differentiation of indoleacetic acid (IAA) and indolebutyric acid (IBA) in plant samples is described. The color change is based upon the reaction between the auxins and p-(dimethylamino)benzaldehyde (PDAB, Ehrlich reagent) following the electrophilic substitution
