Anthropogenic organohalide contaminants present in wastewater treatment plants (WWTPs) often remain untreated and can be discharged into the environment. Although organohalide respiring bacteria (OHRB) contribute to the elimination of anthropogenic organohalides in natural anaerobic environments, reductive dehalogenation by OHRB in mainstream WWTPs ...

Primers That Target Functional Genes of Organohalide-Respiring Bacteria
Springer Protocols, 2015Halogenated organic hydrocarbons are problematic environmental pollutants that can be reductively dehalogenated by organohalide-respiring bacteria (OHRB) in anoxic environments. This energy-conserving process is mediated by reductive dehalogenases (RDases).

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.

Isotopic effects of PCE induced by organohalide-respiring bacteria
Environmental Science and Pollution Research, 2017Reductive dechlorination performed by organohalide-respiring bacteria (OHRB) enables the complete detoxification of certain emerging groundwater pollutants such as perchloroethene (PCE). Environmental samples from a contaminated site incubated in a lab-scale microcosm (MC) study enable documentation of such reductive dechlorination processes.

Organohalide-respiring bacteria (OHRB)-mediated reductive dehalogenation is promising in in situ bioremediation of chloroethene-contaminated sites. The bioremediation efficiency of this approach is largely determined by the successful colonization of fastidious OHRB, which is highly dependent on the presence of proper growth niches and microbial ...

Complex I-like enzymes in organohalide-respiring bacteria
2021Complex I (NADH:ubiquinone oxidoreductase, NUO) and complex I-like enzymes have been detected in several organohalide-respiring bacteria at genomic and proteomic levels. The question of the involvement of these enzymes in organohalide respiration remains to be elucidated.

Polychlorinated biphenyls (PCBs) have accumulated in aquatic sediments due to their inherent chemical stability and their presence poses a risk due to their potential toxicity in humans and animals. Granular activated carbon (GAC) has been applied to PCB contaminated sediment sites to reduce the aqueous concentration by sequestration thus reducing the ...

Distribution of Organohalide-Respiring Bacteria between Solid and Aqueous Phases
Environmental Science & Technology, 2014Contemporary microbial monitoring of aquifers relies on groundwater samples to enumerate nonattached cells of interest. One-dimensional column studies quantified the distribution of bacterial cells in solid and the aqueous phases as a function of microbial species, growth substrate availability and porous medium (i.e., Appling soil versus Federal Fine ...

Genetic System of Organohalide-Respiring Bacteria
2013Organohalide-respiring bacteria (OHRB) utilize halogenated organic compounds as terminal electron acceptors and are considered to be significantly important from both viewpoints of bioremediation and natural halogen cycle. Growth-linked bioremediation using OHRB has been successfully applied to removal of chlorinated solvents, e.g., tetrachloroethene ...

Comparative Physiology of Organohalide-Respiring Bacteria
2016The potential for reductive organohalide respiration is relatively widespread among bacteria. In this chapter, we highlight metabolic differences between facultative and obligate organohalide-respiring bacteria. In addition, we compare the genomic architecture and evolution of the bacteria that comprise the obligate organohalide-respiring ...
