Complete Reductive Dechlorination of 4-Hydroxy-chlorothalonil by Dehalogenimonas Populations.

Environmental Science and Technology, 2022
Chlorothalonil (2,4,5,6-tetrachloroisophthalonitrile, TePN) is one of the most widely used fungicides all over the world. Its major environmental transformation product 4-hydroxy-chlorothalonil (4-hydroxy-2,5,6-trichloroisophthalonitrile, 4-OH-TPN) is ...

Effect of Copresence of Zerovalent Iron and Sulfate Reducing Bacteria on Reductive Dechlorination of Trichloroethylene.

Environmental Science and Technology, 2021
Sulfur amendment of zerovalent iron (ZVI) materials has been shown to improve the reactivity and selectivity of ZVI toward a select group of organohalide contaminants in groundwater, most notably trichloroethene (TCE).

Microbial reductive dechlorination of PCBs

Biodegradation, 1993
Reductive dechlorination is an advantageous process to microorganisms under anaerobic conditions because it is an electron sink, thereby allowing reoxidation of metabolic intermediates. In some organisms this has been demonstrated to support growth.

Nitrogen fixation by reductively dechlorinating bacteria

Environmental Microbiology, 2006
Summary Significant advances in the ecology, physiology and genetics of reductively dechlorinating bacteria have revealed their important environmental roles in bioremediation and in the global chlorine cycle. N 2 fixation has been widely observed in symbiotic, associative ...

Reductive dechlorination of chlorobiphenylols by rats

Experientia, 1977
Dechlorinated products were isolated from the urine of rats that were administered chlorobiphenylols, the primary hydroxylated metabolites of PCB in mammals. The mechanism of chlorine loss from chlorobiphenylols is different from the mechanism of dechlorination via arene oxides whereby concomitant hydroxylation is always observed.

Reductive Dechlorination of Chlorinated Aromatics

Synthetic Communications, 1993
Abstract A practical method has been found for the reduction of PCB's and chlorinated benzenes in a nonpolar solvent with formic acid, water, Pd/C and sodium carbonate. This reductive dechlorination can be run under atmospheric pressure and relatively mild conditions.

Zeolite Imidazolate Framework-8 Metal–Organic Frameworks Embedded with Bimetallic Fe/Pd Nanoparticles for Reductive Dechlorination

, 2020
Bimetallic Fe/Pd nanoparticles are often used for reductive dechlorination. However, the disadvantage of using bimetallic nanoparticles is their potential aggregation, and hence reduced reactivity....

Reductive dechlorination of DDT by haem proteins

Bioinorganic Chemistry, 1977
DDT1 is converted to DDD by reduced myoglobin (rapidly), cytochrome c oxidase, and a haem-containing undecapeptide derived from cytochrome c. Cytochrome c itself is inactive. This demonstrates that an accessible haem site is necessary for the reaction. Spectrophotometric evidence is presented for an interaction between DDT and the undecapeptide.

Reductive dechlorination for remediation of polychlorinated biphenyls

Chemosphere, 2012
Technologies such as thermal, oxidative, reductive, and microbial methods for the remediation of polychlorinated biphenyls (PCBs) have previously been reviewed. Based on energy consumption, formation of PCDD/F, and remediation efficiency, reductive methods have emerged as being advantageous for remediation of PCBs.

Metabolic Synergy of Dehalococcoides Populations Leading to Greater Reductive Dechlorination of Polychlorinated Biphenyls.

Environmental Science and Technology
Polychlorinated biphenyls (PCBs) are dioxin-like pollutants that cause persistent harm to life. Organohalide-respiring bacteria (OHRB) can detoxify PCBs via reductive dechlorination, but individual OHRB are potent in dechlorinating only specific PCB ...
