Degradation of catechin by Bradyrhizobium japonicum

  title={Degradation of catechin by Bradyrhizobium japonicum},
  author={Waheeta Hopper and Ayyamperumal Mahadevan},
Rhizobia utilize phenolic substances as sole carbonsource. Bradyrhizobium japonicum utilizescatechin, a unit of condensed tannin as carbonsource. To establish the degradative pathway ofcatechin, the products of catechin degradation wereisolated by paper chromatography and TLC andidentified by HPLC, UV, IR and NMR spectra. B.japonicum cleaves catechin through catechinoxygenase. Phloroglucinolcarboxylic acid andprotocatechuic acid were identified as the initialproducts of degradation… 
Biodegradation of the phytoestrogen luteolin by the endophytic fungus Phomopsis liquidambari
Results revealed that P. liquidambari can biodegrade luteolin efficiently and could potentially be used to bioremediate phytoestrogen contamination.
Hydrolysable Tannins and Biological Activities of Meriania hernandoi and Meriania nobilis (Melastomataceae)
A bio-guided study of leaf extracts allowed the isolation of two new macrobicyclic hydrolysable tannins and oct-1-en-3-yl β-xylopyranosyl-(1”-6’)-β-glucopyranoide from Meriania hernandoi, in addition to 11 known compounds reported for the first time in the Merianiania genus.
Post symbiotic analysis of the Bradyrhizobium japonicum-soybean symbiosis : proteomics and mutagenesis of protocatechuate 3, 4-dioxygenase paralogs
Proteins were isolated from the periplasm of Bradyrhizobium japonicum bacteroids by a modification of the method of Streeter and LeRudilier (1990) and compared to those isolate from the cytoplasm and found a theme in the carbon and amino acid metabolism groups of thePeriplasmic proteins was the production of succinate.
Enzymatic activity of cell-free extracts from Burkholderia oxyphila OX-01 bio-converts (+)-catechin and (−)-epicatechin to (+)-taxifolin
The results suggest that the OX-01 may have evolved to target both (+)-catechin and (−)-epicatechin, which are major structural units in plants.
Comparative study of the phenolic composition in lentils processed with and without addition of commercial tannase.
The phenolic composition of lentil flour samples, processed with and without the addition of tannase during different times of incubation, 30, 60, 90, 120, 150 and 180 min, were analyzed by high
Naringenin degradation by the endophytic diazotroph Herbaspirillum seropedicae SmR1.
It is shown that this operon is involved in naringenin degradation and that its expression is induced by naringanin and chrysin, two closely related flavonoids.
Oxalate contributes to the resistance of Gaillardia grandiflora and Lupinus sericeus to a phytotoxin produced by Centaurea maculosa
Addition of exogenous oxalate to native grasses and Arabidopsis thaliana (L.) Heynh grown in vitro alleviated the phytotoxic effects of catechin, supporting the field experiments and suggesting that root-secreted oxalates may also act as a chemical facilitator for plant species that do not secrete the compound.


Degradation of aromatic compounds byRhizobium spp.
The ability of rhizobia to utilize catechol, protocatechuic acid, salicylic acid, p-hydroxybenzoic acid and catechin was investigated and Catechol and protocatechuate acid were directly cleaved by the species.
Utilization of catechin and its metabolites by Bradyrhizobium japonicum
Catechin-induced cells oxidized catechin more rapidly than uninduced cells, and the two final ring compounds of the cate chin catabolic pathway, protocatechuic acid and hydroxyquinol, were oxidized differentially.
Rhizobia catabolize nod gene-inducing flavonoids via C-ring fission mechanisms
The initial structural modification of nod gene-inducing flavonoids by rhizobia can generate chalcones, whose open C-ring system may have implications for the binding of inducers to the nodD gene product.
Degradation of certain aromatic compounds by rhizobia
Chemotaxis to aromatic and hydroaromatic acids: comparison of Bradyrhizobium japonicum and Rhizobium trifolii
Using a quantitative capillary assay to measure chemotaxis, the ability of hydroaromatic acids, selected aromatic acids, and their metabolites to serve as chemoattractants for two distantly related rhizobial species, Bradyrhizobium japonicum and R. trifolii, was tested.
Metabolism of resorcinylic compounds by bacteria: alternative pathways for resorcinol catabolism in Pseudomonas putida
Data is presented which shows that one strain of Pseudomonas putida ORC catabolizes resorcinol by a metabolic pathway via hydroxyquinol and ortho oxygenative cleavage to give maleylacetate, but that the other strain (O1) yields mutants that utilize res orcinol.
Utilization of catechin byRhizobium sp.
Rhizobium sp. isolated fromLeucaena leucocephala utilized catechin as sole carbon source. Optimum growth occurred at 2 to 5 mM. From replacement cultures containing catechin, phloroglucinolcarboxylic
Nutritional diversity of Rhizobiaceae revealed by auxanography
Conservation of pathways for aromatic catabolism against a background of wide evolutionary divergence among the Rhizobiaceae suggests that pressures for selection of the traits were exerted throughout the evolutionary history of the organisms.
Astringency in fruits. I. Microbial degradation of catechin.
The studies indicated that Aspergillus flavus (dicat) was the most active of the organisms tested for the degradation of catechin and was optimal at pH 5.0 and 0.3% cATEchin.
Metabolism of resorcinylic compounds by bacteria: new pathway for resorcinol catabolism in Azotobacter vinelandii
Evidence is presented to document a third pathway for the microbial catabolism of resorcinol, which is converted to pyrogallol by res orcinol-grown cells of Azotobacter vinelandii and is the substrate for one of two ring cleavage enzymes induced by growth with resorinol.
