General description

通过混合二甲氨基苯甲醛、异戊醇和浓盐酸,可以制备Kovac试剂。为了鉴定微生物,利用色氨酸底物生成吲哚是一种实用的诊断工具。吲哚产生是鉴定大肠杆菌的关键试验。孵育后,添加试剂将有助于确定是否已产生吲哚。当与吲哚反应时,试剂变红。

Application

Kovac试剂可用于斑点实验,通过用试剂饱和滤纸来测定吲哚。它也可以用于初始斑点实验以测定吲哚,然后通过分光光度测定法和HPLC-UV/Vis-MS/MS方法进行定量。
在有氧的情况下,某些细菌(如大肠杆菌)能够将色氨酸分解为吲哚和α-氨基丙酸。该试剂可用于检测吲哚并鉴定吲哚阳性和吲哚阴性的微生物。

For microbiologists the most fundamental stain was developed in 1884 by the Danish bacteriologist Hans Christian Gram.

There are many other methods of detection to indicate the presence of E. coli. Review common tests and biochemical reactions for this contaminant.
