Transformations of halogenated organic compounds under denitrification conditions.
Trihalomethanes, carbon tetrachloride, 1,1,1-trichloroethane, 1,2-dibromoethane, chlorinated benzenes, ethylbenzene, and naphthalene at concentrations commonly found in surface and groundwater were incubated under anoxic conditions to study their transformability in the presence of denitrifying bacteria. None of the aromatic compounds showed significant utilization relative to sterile controls ...
متن کاملQuantitative structure-activity relationships for toxicity and genotoxicity of halogenated aliphatic compounds: wing spot test of Drosophila melanogaster.
Halogenated aliphatic compounds were evaluated for toxic and genotoxic effects in the somatic mutation and recombination test employing Drosophila melanogaster. The tested chemicals included chlorinated, brominated and iodinated; mono-, di- and tri-substituted; saturated and unsaturated alkanes: 1,2-dibromoethane, 1-bromo-2-chloroethane, 1-iodopropane, 2,3-dichloropropene, 3-bromo-1-propene, ep...
متن کاملDegradation of halogenated aliphatic compounds by Xanthobacter autotrophicus GJ10.
A bacterium that is able to utilize a number of halogenated short-chain hydrocarbons and halogenated carboxylic acids as sole carbon source for growth was identified as a strain of Xanthobacter autotrophicus. The organism constitutively produces two different dehalogenases. One enzyme is specific for halogenated alkanes, whereas the other, which is more heat stable and has a higher pH optimum, ...
متن کاملBacterial Growth on Halogenated Aliphatic Hydrocarbons: Genetics and Biochemistry
Many synthetically produced halogenated aliphatic compounds are xenobiotic chemicals in the sense that they do not naturally occur on earth at biologically significant concentrations. Nevertheless, various microorganisms have been isolated that possess the capacity to grow at the expense of these compounds, and to use them as a carbon and energy source under aerobic conditions. This raises a nu...
متن کاملBiodegradation of halogenated organic compounds.
In this review we discuss the degradation of chlorinated hydrocarbons by microorganisms, emphasizing the physiological, biochemical, and genetic basis of the biodegradation of aliphatic, aromatic, and polycyclic compounds. Many environmentally important xenobiotics are halogenated, especially chlorinated. These compounds are manufactured and used as pesticides, plasticizers, paint and printing-...
