Association between Smoking and Urine Indole Levels Measured by a Commercialized Test [PDF]

Metabolites, 2022
Indoles are formed from dietary tryptophan by tryptophanase-positive bacterium. A few amounts of indole are excreted in the urine. On the other hand, cigarette smoke contains indoles, which could also change the urine indole levels.

Indole Derivative Feeding Test and Detection of TRP and Indole derivatives by Thin Layer Chromatography

Bio-Protocol, 2013
The mutualistic root endophyte Piriformospora indica colonizes a wide range of plants and the colonization of root cells by this fungus is very often associated with beneficial effects to its host, such as growth promotion and increased biotic and ...

Structure-mutagenicity relationships on quinoline and indole analogues in the Ames test [PDF]

Genes and Environment
Background Although the in silico predictive ability of the Ames test results has recently made remarkable progress, there are still some chemical classes for which the predictive ability is not yet sufficient due to a lack of Ames test data.

Evaluation of a New Incubation-Type Indole Strip Test [PDF]

Applied Microbiology, 1970
A total of 189 of Enterobacteriaceae and three strains of Clostridium perfringens were tested with a new incubation-type indole paper strip. This 4-hr incubation test gave the same results as a standard 48-hr indole test, except with some strains of Proteus rettgeri ...

Preliminary Test of the Reduction Capacity for the Intestinal Adsorption of Skatole and Indole in Weaning Piglets by Pure and Coated Charcoal [PDF]

Animals, 2021
To reduce the risk of boar taint, intact male piglets are immuno- or surgically castrated. One alternative is reducing skatole by adding skatole reducing or adsorbing substances to the boars’ diet.

Ability Test of IAA (Indole-3-Acetic Acid) Hormone-Producing Endophytic Bacteria from Lamongan Mangrove

Jurnal Riset Biologi dan Aplikasinya, 2022
Most of the plant-associated bacteria can synthesize active biological components of phytohormones such as auxin. This study aimed to examine the potency of 61 endophytic bacteria isolates from the mangroves at Kutang Beach, Lamongan in producing IAA ...

The Para-dimethyl-amido-benzaldehyde Test for Indole [PDF]

Epidemiology and Infection, 1907
1. The high estimate formed by Böhme of the utility of this test has been fully confirmed.2. Other substances, such as skatole-carboxylic acid, which tended to confuse the results of the older method, do not give an indole-like reaction with this reagent.3.

Differentiation of Haemophilus spp. in Respiratory isolate cultures by an indole spot test [PDF]

Journal of Clinical Microbiology, 1982
Indole spot tests using isolated, nonhemolytic colonies of Haemophilus species were positive for 90 of 151 (60%) respiratory isolates of Haemophilus influenzae, whereas 67 to 72 (93%) isolates of H. influenzae from cerebrospinal fluid and blood specimens were indole positive.
