indole has various use in industries of perfume, pharma . It is used to prepare jasmine oil, orange oil and it is found in coal tar.
class of alkaloids containing a structural moiety of indole.
The indole test is a biochemical test performed on bacterial species to determine the ability of the organism to split indole from the amino acid tryptophan. This division is performed by a chain of a number of different intracellular enzymes, a system generally referred to as "tryptophanase."
Sulfur Indole Motility test
Indole test,Proteus vulgaris is be indole positive and Citrobacter freundii will be indole negative
The indole test is based on the ability of certain bacteria to produce the enzyme tryptophanase, which converts tryptophan into indole. This indole is then detected by adding a reagent such as Kovac's reagent, which reacts with indole to produce a red color. A positive test indicates the presence of tryptophanase enzyme in the bacteria.
A negative indole test typically shows no color change, indicating the absence of indole production. The medium remains yellow or unchanged, suggesting that the tested organism does not possess the enzyme tryptophanase, which is responsible for converting tryptophan to indole.
S.aureus is a positive gram. Indole test is a part the biochemistry test to determinate a bacteria negative gram. indole test used to determine S.aureus, the result is negative. That is improve which S.aureus haven't trytophanase enzym (please see indole test principle)bcb
Shigella species are generally indole negative, except for Shigella flexneri, which can be indole positive depending on the specific strain. In laboratory identification, indole testing is used to differentiate between various enteric bacteria. Therefore, while most Shigella species do not produce indole, Shigella flexneri may show positive results under certain conditions.
The indole positive test is used to test the absence or presence of the vibro cholera.
Indole is more basic than pyrrole due to the presence of the nitrogen atom in the benzene ring of the indole structure. The lone pair of electrons on the nitrogen atom in indole makes it more basic compared to pyrrole, which lacks this nitrogen atom in the benzene ring.
The chemical name for auxin is indole-3-acetic acid (IAA).
The chemical formula of indole-3-acetic acid is C10H9NO2.
