Production and Oxidation of Indole by Haemophilus influenzae [PDF]
During growth in high concentrations of iron nitrate, H. influenzae produces compounds reactive in biochemical assays for hydroxamates. Mixing experiments established that nitrate was responsible for inducing these compounds. Analysis by 1H and 13C NMR and high resolution mass spectrometry identified the active species as 2,2-bis(3'-indolyl)indoxyl ...

Indol production by bacteria [PDF]
ABSTRACT Production of indol by bacteria appears to be limited to those which produce acid from glucose fermentatively and reduce nitrate. From more limited experience, Gram - positive and pigmented bacteria did not produce indol.

PRODUCTION OF FREE INDOLE BY SOME AROIDS
SUMMARY The production of free indole by several arum lily species (Araceae) was studied. The compound was identified by paper chromatography and thin-layer chromatography in several solvent systems, colour reactions with various reagents, enzymatic conversion to tryptophan, UV absorption spectrum, and formation of a complex with polynitrofluorenone.

Managemental influences on the selective proliferation of two strains of haemolytic Escherichia coli in weaned pigs [PDF]
In an experimental study on a piggery it was found that haemolytic Escherichia coli of O-serotypes 138 or 139 proliferated in the intestinal tracts of pigs following weaning, with E.

Targeting the gut microbial metabolic pathway with small molecules decreases uremic toxin production
Uremic toxins are a class of toxins that accumulate in patients with chronic kidney disease (CKD). Indoxyl sulfate (IS), a typical uremic toxin, is not efficiently removed by hemodialysis.

Indole ring oxidation by activated leukocytes prevents the production of hypochlorous acid
Hypochlorous acid (HOCl) released by activated leukocytes has been implicated in the tissue damage that characterizes chronic inflammatory diseases. In this investigation, 14 indole derivatives, including metabolites such as melatonin, tryptophan and ...

Clinical Persistence of Chlamydia trachomatis Sexually Transmitted Strains Involves Novel Mutations in the Functional αββα Tetramer of the Tryptophan Synthase Operon. [PDF]
Clinical persistence of Chlamydia trachomatis (Ct) sexually transmitted infections (STIs) is a major public health concern. In vitro persistence is known to develop through interferon gamma (IFN-γ) induction of indoleamine 2,3-dioxygenase (IDO), which ...

EIN2 and COI1 control the antagonism between ethylene and jasmonate in adventitious rooting of Arabidopsis thaliana thin cell layers [PDF]
Auxins induce adventitious roots (ARs) in numerous culture-systems, and indole-3-butyric acid (IBA) is frequently the best AR-inducer. Vitamin requirements vary according to species, explant, and culture-conditions. Arabidopsis thaliana thin cell layers (
