Microbial hydroxylation of indole to 7-hydroxyindole by Acinetobacter calcoaceticus strain 4-1-5.

A screening study yielded Acinetobacter calcoaceticus strain 4-1-5, which is capable of hydroxylating indole to 7-hydroxyindole. Strain 4-1-5 grew on terephthalate as the sole source of carbon and energy and hydroxylated indole to 7-hydroxyindole by cometabolism of indole using terephthalate as cosubstrate. Strain 4-1-5 produced 0.574 mM of 7-hydroxyindole at 2.38 mM indole in 24 h with the cel...

Microbial Hydroxylation of Indole Alkaloids.

The hydroxylation of the indole-type alkaloids, yohimbine, alpha-yohimbine, beta-yohimbine, and corynanthine, was achieved with several genera of higher fungi and species of Streptomyces. Microorganisms were found which monohydroxylated these compounds in three different positions. The site of hydroxylation was strain-specific for two strains of Cunninghamella echinulata and C. bainieri.

Indole and 7‐hydroxyindole diminish Pseudomonas aeruginosa virulence

Indole is an extracellular biofilm signal for Escherichia coli, and many bacterial oxygenases readily convert indole to various oxidized compounds including 7-hydroxyindole (7HI). Here we investigate the impact of indole and 7HI on Pseudomonas aeruginosa PAO1 virulence and quorum sensing (QS)-regulated phenotypes; this strain does not synthesize these compounds but degrades them rapidly. Indole...

Microbial 7 ao - Hydroxylation of 3 - Ketobisnorcholenol

The transformation of 22-hydroxy-23,24-bisnorchol-4-en-3-one to 7a-22-dihydroxy-23,24-bisnorchol-4-en3-one by Botryodiploida theobromae, Lasiodiplodia theobromae, and various Botryosphaeria strains is described. Factors affecting the reaction were incubation temperature, sonication of the substrate, and addition of 2,2'-dipyridyl, extra carbohydrate, and Amberlite XAD-7. The enzyme responsible ...

5-Chloro-1-(4-methyl­phenyl­sulfon­yl)-1H-indole

In the title compound, C15H12ClNO2S, the indole ring is essentially planar (r.m.s. deviation = 0.0107 Å) and makes a dihedral angle of 85.01 (6)° with the benzene ring. In the crystal, three C-H⋯O hydrogen bonds result in a hydrogen-bonded spiral running parallel to the c axis.
