說明
一般描述
Kovac′s reagent is a biochemical reagent composed of n-Butanol, hydrochloric acid, ａnd 4-dimethylaminobenzaldehyde. It is used for the detection of indole producing microorganisms. Tryphan is abundant in trypticalle digested peptone. Some microorganisms can cleave tryphan to give pyruvic acid, ammonia, ａnd indole. Indole then reacts with 4-dimethylaminobenzaldehyde to form a dark red dye. As tryphan also gives a color reaction with 4 dimethylaminobenzaldehyde, it must be separated from the indole. This is achieved by selectively extracting indole with butanol.
應用
Bactident™ Kovac′s Indole reagent is used for the detection of indole producing microorganisms in food ａnd beverages, ａnd environmental samples. This is suitable for the identification of E. coli.
