Organohalide-Respiring Bacteria—An Introduction
2016Organohalide-respiring bacteria (OHRB) “breath” halogenated compounds for energy conservation. This fascinating process has received increasing attention over the last two decades revealing the physiological, biochemical, genomic, and ecological features of this taxonomically diverse bacterial group.

Comparative Biochemistry of Organohalide Respiration
2016Corrinoid-containing reductive dehalogenases (RDases) play a key role in the energy metabolism of anaerobic organohalide-respiring bacteria (OHRB). In such microorganisms the reductive dehalogenation of organohalides catalyzed by RDases is coupled to ATP synthesis via electron transport phosphorylation. The overview presented here summarizes the actual

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 ...

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 ...

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.

Energiekonservierung über Organohalid-Respiration in Sulfurospirillum multivorans
2018The epsilonproteobacterium Sulfurospirillum multivorans is able to couple the reductive dechlorination of tetrachloroethene (PCE) to energy conservation via electron transport phosphorylation (organohalide respiration). The key enzyme of this anaerobic respiration is the reductive PCE dehalogenase (PceA).

Primers That Target Functional Genes of Organohalide-Respiring Bacteria
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).

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.

Environmental Science & Technology
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 ...
