Indole Test- Principle, Reagents, Procedure, Result Interpretation and ...
Aug 10, 2022 · Principle of Indole Test. Tryptophan is an amino acid that can undergo deamination and hydrolysis by bacteria that express tryptophanase enzyme. Indole is generated by reductive deamination from tryptophan via the intermediate molecule indolepyruvic acid.
Indole test - Wikipedia
The indole test is a biochemical test performed on bacterial species to determine the ability of the organism to convert tryptophan into indole. This division is performed by a chain of a number of different intracellular enzymes , a system generally referred to as " tryptophanase ."
Indole Test: Principle, Procedure, Results • Microbe Online
Indole test is used to determine the ability of an organism to split amino acid tryptophan to form the compound indole. It is used as part of the IMViC procedures to differentiate members of the family Enterobacteriaceae. Tryptophan is hydrolyzed by tryptophanase to produce three possible end products; indole, pyruvate, and ammonia.
Indole Test- Principle, Media, Procedure, Types, Results, Uses
Jan 23, 2022 · Indole test is a biochemical test conducted on bacterial species to detect their ability to produce indole from tryptophan in the presence of a group of enzymes called ‘tryptophanase’. It is a qualitative test that tests the conversion of tryptophan into indole.
Inoculate the tube of tryptone broth with a small amount of a pure culture. Incubate at 35°C (+/- 2°C) for 24 to 48 hours. To test for indole production, add 5 drops of Kovács reagent directly to the tube (3, 5).
