Production of Indole by Escherichia coli

Nature, 1948
THE mechanism of the production of indole by Escherichia coli has attracted the attention of many workers since Hopkins and Cole1 first demonstrated that the precursor of indole is tryptophan. The problem is an intriguing one among the bacterial degradation of amino-acids, inasmuch as fission of a carbon-carbon bond occurs at a position in the molecule

Production of indole diterpenes by Aspergillus alliaceus

Biotechnology and Bioengineering, 2006
AbstractProduction of two related indole diterpenes (differing by a dimethyl leucine side chain) by Aspergillus alliaceus was improved through several pilot scale fermentations. Media were optimized through focus primarily on initial increases, as well as mid‐cycle additions, of carbon and nitrogen sources.

Extracellular Production of Indolics by the Fungus Cyathus

Mycologia, 1971
Three species of Cyathus, C. africanas Brodie, C. helenae Brodie, and C. striatus (Huds.) ex Pers., were chosen for a study of the extracellular production of indolic substances.

THE REACTION PRODUCTS OF INDOLS WITH DIAZOESTERS

Canadian Journal of Research, 1935
In conformity with findings of previous work on indols and in contradistinction to more recent work on pyrrols, the action of diazoesters on indol leads to 3-substituted as well as a small amount of 1:3-disubstituted derivatives. The formation of 2-substituted derivatives could not be demonstrated.

Photoreaction of indole-containing mycotoxins to fluorescent products

Mycotoxin Research, 2009
Photochemical reaction of the non-fluorescent mycotoxin cyclopiazonic acid (CPA) to fluorescent products was recently reported. Because CPA contains an indole moiety, believed to contribute to the fluorescence, it was of interest to determine whether the effect might be more generally applicable to indole-containing mycotoxins.

ESP and ESM1 mediate indol-3-acetonitrile production from indol-3-ylmethyl glucosinolate in Arabidopsis

Phytochemistry, 2008
Glucosinolates are plant secondary metabolites that act as direct defenses against insect herbivores and various pathogens. Recent analysis has shown that methionine-derived glucosinolates are hydrolyzed/activated into either nitriles or isothiocyanates depending upon the plants genotype at multiple loci.

Evolution of benzoxazinone biosynthesis and indole production in maize

Planta, 2001
The synthesis of a diverse spectrum of secondary metabolites has allowed plants to develop sophisticated chemical defense mechanisms. Maize (Zea mays L.), for example, releases a cocktail of volatile compounds when attacked by a caterpillar. These compounds attract a parasitic wasp, which deposits its eggs in the larvae, thereby controlling the ...

Sensitive reagents for detection of indole production by bacteria

Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. Series A: Medical Microbiology, Infectious Diseases, Virology, Parasitology, 1986
A number of substituted 4-aminobenzaldehydes were compared with more commonly employed reagents for the detection of indole-producing organisms among the Enterobacteriaceae. Factors such as rate of colour intensity and stability were compared in tests with reference organisms and clinical isolates, and with appropriate concentrations of pure indolic ...
