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

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 ...

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.

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 ...
