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 ...

Comparison of the genomes of organohalide-respiring bacteria has improved our understanding of the genetic background of the organohalide respiration process. In this chapter the remarkable differences between obligate and facultative organohalide-respiring bacteria in the number of reductive dehalogenase-encoding genes and the numbers and types of ...

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 ...

Exploiting the ecogenomics toolbox for environmental diagnostics of organohalide-respiring bacteria
Trends in Biotechnology, 2010Various 'omics' methods have enabled environmental probing at the molecular level and have created an important new paradigm in bioremediation design and management. Ecogenomics - the application of genomics to ecological and environmental sciences - defines phylogenetic and functional biodiversity at the DNA, RNA and protein levels.

Biodegradation, 2014
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.

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 ...

Application of Fenton's reagent and enhanced reductive dechlorination are currently the most common remediation strategies resulting in removal of chlorinated ethenes. In this study, the influence of such techniques on organohalide-respiring bacteria was assessed at a site contaminated by chlorinated ethenes using a wide spectrum of molecular genetic ...
