Regulation of Organohalide Respiration
Advances in Microbial Physiology, 2019 Organohalide respiration (OHR) is an anaerobic metabolism by which bacteria conserve energy with the use of halogenated compounds as terminal electron acceptors. Genes involved in OHR are organized in reductive dehalogenase (rdh) gene clusters and can be found in relatively high copy numbers in the genomes of organohalide-respiring bacteria (OHRB). The

Structural Basis for Organohalide Respiration
Science, 2014 How bacteria break down organohalides Anaerobic bacteria can break down a range of organohalide pollutants. To do so, they use unusual reductive dehalogenase enzymes that remove the halogen ion from the molecule, making the pollutants less toxic. Bommer et al. describe x-ray

Organohalide Respiration with Diclofenac by Dehalogenimonas
Environmental Science & Technology, 2022Diclofenac (DCF) is a pharmaceutically active contaminant frequently found in aquatic ecosystems. The transformation pathways and microbiology involved in the biodegradation of DCF, particularly under anoxic conditions, remain poorly understood. Here, we demonstrated microbially mediated reductive dechlorination of DCF in anaerobic enrichment culture ...

Glucose facilitates the acclimation of organohalide-respiring bacteria
Journal of Hazardous Materials, 2023Organohalide respiring bacteria (OHRB) are the mainstay for bioremediation of organohalide contaminated sites. Enrichment screening of OHRB is prerequisite for the development of high performance dehalogenating bacterial agents. Herein, different domestication strategies were formulated for the main factors (nutrients and inocula) affecting the ...

Genomic Insights Into Organohalide Respiration
Current Opinion in Biotechnology, 2013In the last few years there has been a burst of genomes released for organohalide respiring bacteria (referred to as OHRB herein though the process is otherwise known as dehalorespiration, reductive dechlorination, or halorespiration). The microorganisms are employed in bioremediation of sites contaminated with chlorinated ethene, ethane, and methanes,
