Organohalide-Respiring Bacteria—An Introduction

2016
Organohalide-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.

Exploiting the ecogenomics toolbox for environmental diagnostics of organohalide-respiring bacteria

Trends in Biotechnology, 2010
Various '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.

Comparative Biochemistry of Organohalide Respiration

2016
Corrinoid-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

Ultrastructure of Organohalide-Respiring Dehalococcoidia Revealed by Cryo-Electron Tomography

Applied and Environmental Microbiology, 2022
Dehalococcoidia respire organohalogen compounds and play relevant roles in bioremediation of groundwater, sediments, and soils impacted with toxic chlorinated pollutants. Using advanced imaging tools, we have obtained three-dimensional images at macromolecular resolution of whole Dehalococcoidia cells ...

Offshore Marine Sediment Microbiota Respire Structurally Distinct Organohalide Pollutants

Environmental Science & Technology, 2022
Marine sediments are a major sink of organohalide pollutants, but the potential for offshore marine microbiota to transform these pollutants remains underexplored. Here, we report dehalogenation of diverse organohalide pollutants by offshore marine microbiota.

Distribution of Organohalide-Respiring Bacteria between Solid and Aqueous Phases

Environmental Science & Technology, 2014
Contemporary 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

2013
Organohalide-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

2016
The 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 ...

Electron transport chains in organohalide-respiring bacteria and bioremediation implications

Biotechnology Advances, 2018
In situ remediation employing organohalide-respiring bacteria represents a promising solution for cleanup of persistent organohalide pollutants. The organohalide-respiring bacteria conserve energy by utilizing H2 or organic compounds as electron donors and organohalides as electron acceptors.
