Outlook—The Next Frontiers for Research on Organohalide-Respiring Bacteria
2016Research efforts over the last two decades have substantially advanced the understanding of organohalide-respiring bacteria (OHRB), and this progress has enabled successful bioremediation applications at chlorinated solvent-contaminated sites. Yet, major knowledge gaps remain, and detailed biochemical, genetic, regulatory, evolutionary, taxonomic, and ...

Polybrominated diphenyl ethers (PBDEs) are persistent organic pollutants prevalent in the environment. Organohalide-respiring bacteria (OHRB) can attenuate PBDEs via reductive debromination, but often producing toxic end-products. Debromination of PBDEs to diphenyl ether remains a rare phenomenon and is so far specifically associated with ...

It is acknowledged that organohalide-respiring bacteria (OHRB) can degrade polybrominated diphenyl ethers (PBDEs); however, very little is known about the distribution of OHRB or their response to PBDE contamination in natural sediments. We collected sediments from 28 sampling sites in Taihu Lake, China, and investigated the spatial distribution and ...

Discovery of Organohalide-Respiring Processes and the Bacteria Involved
2016Hazardous halogenated organic compounds are produced industrially for a variety of uses, are highly resistant to degradation by aerobic organisms, and are now widely distributed throughout the natural environment. Discovered in the 1960s were, anaerobic organisms that can transform chlorinated pesticides such as DDT and lindane.

Trichloroethylene (TCE) is one of the most common groundwater contaminants in the United States; however clean-up efforts are a challenge due to its physical and chemical properties. TCE and several of its degradation products were detected in the groundwater of the Beaver Dam Road Landfill site (Beltsville, MD) at concentrations above accepted maximum

Anaerobic reductive dechlorination of hexachlorobenzene (HCB) and three isomers of tetrachlorobenzene (TeCB) (1,2,3,4-, 1,2,3,5- and 1,2,4,5-TeCB) was investigated in microcosms containing chloroaromatic contaminated river sediment. All chlorobenzenes were dechlorinated to dichlorobenzene (DCB) or monochlorobenzene.

Because of the stepwise, progressive nature of reductive dehalogenation reactions, polyhalogenated parent electron acceptors and their corresponding intermediary dehalogenation products are almost always simultaneously present in the environments where these processes occur.

Organohalide-respiring bacteria (OHRB) have been isolated from a wide range of anoxic environments worldwide and can easily be enriched in the laboratory. Obligate OHRB generally thrive best in mixed communities as part of anaerobic food webs that typically involve interspecies hydrogen (H2) transfer from fermenters to OHRB, and often OHRB compete for ...
