Indole-3-lactic acid as a tryptophan metabolite produced by Bifidobacterium spp.
Fifty-one strains of the genus Bifidobacterium have been found to accumulate indole-3-lactic acid in culture broth. The isolated metabolite was identified through mass and nuclear magnetic resonance spectroscopy. All the microorganisms tested, as resting cells, have been shown to be able to convert L-tryptophan into L-indole-3-lactic acid.
متن کاملIndole -3-Acetic Acid Production by the Bacterial Strains Isolated from Vermicomposts in the Presence and Absence of Tryptophan
ABSTRACT: Vermicompost was prepared from leaf materials such as Gliricidia sepium Jacq, Leucaena leucocephala (Lam.) De Wit and Cassia auriculata Linn and earthworms, Eudrilus eugeniae (Kinberg) and Eisenia fetida (Savigny) along with cowdung in six Treatments. Fortnightly analyses (0, 15, 30, 45 and 60 d) of the colony forming units (CFU) of bacteria in vermicomposts, vermicasts and earthworm ...
متن کاملBioproduction of Indole Acetic Acid by Rhizobium Strains Isolated from Root Nodules of Green Manure Crop, Sesbania sesban (L.) Merr.
Twenty six Rhizobium strains were isolated from root nodules of Sesbania sesban (L.) Merr. collected from different regions of Andhra Pradesh. All the 26 Rhizobium strains produced indole acetic acid (IAA), but maximum amount was produced by only five strains in yeast extract mannitol (YEM) medium supplemented with L-tryptophan. The strains were found to elaborate maximum IAA when fed with 2.5...
متن کاملIndole-3-acetic acid (IAA) production by Arthrobacter species isolated from Azolla.
Arthrobacter species, isolated from the leaf cavities and the microsporocarps of the aquatic fern species Azolla pinnata and Azolla filiculoides, produced indole-3-acetic acid (IAA) in culture when the precursor tryptophan was added to the medium. No IAA production was detected in the absence of tryptophan. Maximum IAA formation was obtained in the first 2 d of incubation. Part of the tryptopha...
متن کاملScreening of Lactic Acid Bacteria Strains Isolated from Some Nigerian Fermented Foods for EPS Production
This study was embarked upon to obtain laboratory strains of lactic acid bacteria from some traditional fermented foods, with potential for the production of exopolysaccharides (EPSs), which is an important factor in assuring the proper consistency and texture of fermented food. One hundred and fifteen strains of Lactic Acid Bacteria (LAB) were isolated and characterized from some fermented dai...
