Implementation of a flavin biosynthesis operon improves extracellular electron transfer in bioengineered Escherichia coli
Ardemis Anoush Boghossian, Melania Reggente, Mohammed Mouhib
Bioelectrochemical systems (BES) are promising for energy, sensing, environmental, and synthesis applications. Escherichia coli were previously bioengineered for application in BES by introduction of extracellular electron transfer (EET) pathways. Inspired ...
2023Characterization of the electron-accepting part of the organohalide respiration chain of Dehalobacter and Desulfitobacterium
Organohalide respiration (OHR) is a bacterial anaerobic process that use halogenated compounds, e.g. tetrachloroethene (PCE), as terminal electron acceptors. D. restrictus strain PER-K23, an obligate OHR bacterium (OHRB), and D. hafniense strain TCE1, a ba ...
EPFL2022Organohalide respiration: breakthrough towards the elucidation of the electron-accepting moiety of the respiratory chain
Christof Holliger, Julien Maillard, Adrian Schmid, Lorenzo Cimmino
Background Organohalide respiration (OHR) is a bacterial anaerobic process in which chlorinated compound, e.g. tetrachloroethene (PCE), is used as terminal electron acceptors. Dehalobacter restrictus PER-K23, a paradigmatic organohalide-respiring bacterium ...
2021Insights into the microbial reduction of pentavalent and hexavalent uranium species by Shewanella oneidensis MR-1
Margaux Camille Andréa Molinas
Decades of uranium-related activities such as ore mining, nuclear power generation, weapon manufacture, storage of nuclear wastes, have contributed to the release of U in the environment. U occurrence is concerning, since in surface environments, U is typi ...
EPFL2021ANAEROBIC BIODEGRADATION OF ORGANOHALIDE POLLUTANTS: A CRUCIAL STEP TOWARDS THE ELUCIDATION OF PROTEINS INVOLVED
Christof Holliger, Julien Maillard, Adrian Schmid, Lorenzo Cimmino
Halogenated organic compounds (so-called organohalides) represent one of the major class of groundwater pollutants. The exploration of how organohalides are used as energy source is important in terms of ecosystem remediation but is also essential for the ...
2019Anaerobic Biodegradation of organohalide pollutants: a crucial step towards the elucidation of proteins involved
Christof Holliger, Julien Maillard, Adrian Schmid, Lorenzo Cimmino
Halogenated organic compounds (so-called organohalides) represent one of the major class of groundwater pollutants. The exploration of how organohalides are used as energy source is important in terms of ecosystem remediation but is also essential for the ...
2019Imaging the aerobic granular sludge microbial community using light-sheet fluorescence micros
Christof Holliger, Julien Maillard, Arnaud Michel Gelb, Karen Gemayel
One of the aims of wastewater treatment is the removal of phosphorus before the water is discharged into the environment. Since phosphorus concentrations in wastewater exceed the requirement of bacterial growth, biological phosphorus removal is based on th ...
2019Regulation of organohalide respiration
Julien Maillard, Mathilde Stéphanie Willemin
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 f ...
Academic Press2019RdhC, a family of membrane-bound flavoproteins involved in electron transfer in organohalide respiration ?
Julien Maillard, Romain Hamelin, Mathilde Stéphanie Willemin, Géraldine Florence Buttet
Organohalide respiration (OHR) is a bacterial energy metabolism making use of halogenated compounds – like tetrachloroethene (PCE), a major pollutant – as terminal electron acceptors. Three models of electron transport chain exist for OHR [1], however many ...
2018The membrane-bound C subunit of reductive dehalogenases: topology analysis and reconstitution of the FMN-binding domain of PceC
Julien Maillard, Romain Hamelin, Mathilde Stéphanie Willemin, Géraldine Florence Buttet, Aamani Rupakula Boyanapalli
Organohalide respiration (OHR) is the energy metabolism of anaerobic bacteria able to use halogenated organic compounds as terminal electron acceptors. While the terminal enzymes in OHR, so-called reductive dehalogenases, are well-characterized, the identi ...
