Reductive Dehalogenation by Aqueous Biochars
… targets the reactivity of a�"BCs toward the reductive degradation of organohalogens. This Ph.D. project aims to: 1) study the degradation of organohalogen (with triclosan (TCS) as a model compound) by reduced a�"BCs; 2) investigate the impact of the chemical nature of quinones (QNs) as …

Microbial Growth On Anthropogenic Compounds By Reductive Dehalogenation Or Oxidation
… nature. Dehalococcoides mccartyi strain 195 can reductively dehalogenate some of these compounds and, in the case of tetrachloroethene (PCE), detoxify it by producing ethene. Its genome contains a putative prophage, which could inhibit its ability to grow to high densities and cause phage …

Substrate interactions during the anaerobic biodegradation of 1,1,1-trichloroethane
… and can have adverse effects on human health. Reductive dehalogenation, in which cleavage of carbon-halogen bonds is accompanied by electron transfer to the halogenated substrate, is the most important mechanism for the anaerobic biodegradation of highly halogenated aliphatic hydrocarbons. The …

Isolation and characterization of carbofuran and dicamba degrading bacteria
… of aqueous medium. This was followed by a reductive dehalogenation reaction at the meta position of 3,6-dichlorosalicylic acid forming 6-chlorosalicylic acid. The metabolites were isolated using thin layer chromatography. Confirmation of metabolite identity was achieved using HPLC, and mass …

Removal of Perfluorooctane Sulfonate (PFOS) and Related Compounds From Industrial Effluents
… to minimize discharges of these pollutants. Reductive dehalogenation is widely applied to the degradation of highly chlorinated compounds. Hence, the susceptibility of PFOS and related compounds to biological and chemical reductive dehalogenation was evaluated in batch assays. PFAS were not …

The effects of solvents and nucleophiles on heteroaromatic SRN1 reactions
… and iodobenzene were accompanied by a reductive dehalogenation process. That these reactions involved the abstraction of s-hydrogens from the nucleophile was supported by the isolation of 2,4,4,5,5,7-hexamethyloctane-3,6-dione. Spectral characterizations and the independent synthesis of …

The Microbubble Assisted Bioremediation of Chlorinated Ethenes
… consortia to stimulate their ability to reductively dehalogenate tetrachloroethylene all the way to ethene and ethane. A continuous flow system, consisting of six anaerobic soil column bioreactors, inoculated with sediments from Virginia Tech's Duck Pond, was used for this study. Two …
