Degradation of trichloroethylene by toluene dioxygenase in whole-cell studies with Pseudomonas putida F1.
Toluene-induced cells of Pseudomonas putida F1 removed trichloroethylene from growth media at a significantly greater initial rate than the methanotroph Methylosinus trichosporium OB3b. With toluene-induced P. putida F1, the initial degradation rate varied linearly with trichloroethylene concentration over the range of 8 to 80 microM (1.05 to 10.5 ppm). At 80 microM (10.5 ppm) trichloroethylene...
متن کاملTrichloroethylene degradation by Escherichia coli containing the cloned Pseudomonas putida F1 toluene dioxygenase genes.
Toluene dioxygenase from Pseudomonas putida F1 has been implicated as an enzyme capable of degrading trichloroethylene. This has now been confirmed with Escherichia coli JM109(pDTG601) that contains the structural genes (todC1C2BA) of toluene dioxygenase under the control of the tac promoter. The extent of trichloroethylene degradation by the recombinant organism depended on the cell concentrat...
متن کاملOxidative carbonylation of toluene to p-toluic acid catalyzed by rhodium in the presence of vanadium and oxygen
The mechanism and kinetics of the liquid phase, oxidative carbonylation of toluene to toluic acid were investigated. The catalyst system consisted f Rh(acac)3, NH4VO3, trifluoroacetic acid (TFAH), and trifluoracetic anhydride (TFAA). Liquid toluene together with gaseous CO and O2 was sed as the reactant. The effects of temperature, the partial pressures of O2 and CO, the concentrations of TFAH ...
متن کاملSubtle difference between benzene and toluene dioxygenases of Pseudomonas putida.
Benzene dioxygenase and toluene dioxygenase from Pseudomonas putida have similar catalytic properties, structures, and gene organizations, but they differ in substrate specificity, with toluene dioxygenase having higher activity toward alkylbenzenes. The catalytic iron-sulfur proteins of these enzymes consist of two dissimilar subunits, alpha and beta; the alpha subunit contains a [2Fe-2S] clus...
متن کاملPathways for the degradation of m-cresol and p-cresol by Pseudomonas putida.
A comparison of the oxidation rates of various compounds by whole cells of Pseudomonas putida 3, 5 indicated that m-cresol is metabolized by oxidation to 3-hydroxybenzoate followed by hydroxylation to gentisate, the ring-fission substrate, when grown with 3, 5-xylenol. However, when m-cresol was the growth substrate, similar experiments suggested a different pathway involving a methyl-substitut...
