| Chlorinated ethenes such as tetrachloroethene (PCE) and trichloroethene (TCE) are some of the most common groundwater contaminants found at Department of Defense (DoD) facilities. In addition to their common presence, these compounds are persistent under most natural geochemical conditions at these contaminated sites. Remediation of these sites through biodegradation of the chlorinated ethenes is a promising alternative at many of the sites. Reductive dechlorination is the primary pathway for biodegradation ... |

|
| Study of the fate of chemicals on substrates requires that those chemicals be applied to the substrate in a uniform and reproducible manner. Relatively simple means of droplet deposition of non-viscous chemicals are satisfactory, however thickened chemicals present problems using the same deposition techniques. By using supercritical carbon dioxide as a diluent, we were able to reduce the viscosity of various polymer-thickened chemicals and store them in a high-pressure reservoir. ... |

|
| An oxidative pathway for the mineralization of 2,4-dinitrotoluene (2, 4-DNT) by Burkhoderia sp. strain DNT has been reported previously. We report here the isolation of additional strains with the ability to mineralize dinitrotoluene (2,6-DNT) by a different pathway. Burkizodena cepacia strain JS85O and Hydrogenephaga palleronii strain JS863 grew on 2,6-DNT as the sole source of carbon and nitrogen. The initial steps in the pathway metabolites through mass spectroscopy and nuclear ... |

|
| 3-Hydroxylaminophenol mutase from Ralstonia eutropha JMP134 is involved in the degradative pathway of 3-nitrophenol, in which it catalyzes the conversion of 3-hydroxylaminophenol to aminohydroquinone. To show that the reaction was really catalyzed by a single enzyme without the release of intermediates, the corresponding protein was purified to apparent homogeneity from an extract of cells grown on 3-nitrophenol as the nitrogen source and succinate as the carbon and energy source. 3-Hydroxylaminophenol ... |

|
| Because of its high electron deficiency, initial microbial transformations of 2,4,6-trinitrotoluene (TNT) are characterized by reductive rather than oxidation reactions. The reduction of the nitro groups seems to be the dominating mechanism, whereas hydrogenation of the aromatic ring, as described for picric acid, appears to be of minor importance. Thus, two bacterial strains enriched with TNT as a sole source of nitrogen under aerobic conditions, a gram-negative strain called TNT-8 ... |
