Temporal evolution of bacterial communities associated with the in situ wetland-based remediation of a marine shore porphyry copper tailings deposit

Christof Holliger, Emmanuelle Rohrbach, Nouhou Diaby, Pierre Rossi

Mine tailings are a serious threat to the environment and public health. Remediation of these residues can be carried out effectively by the activation of specific microbial processes. This article presents detailed information about temporal changes in ba ...

Use of silicate minerals for long-term pH control during reductive dechlorination of high tetrachloroethene concentrations in continuous flow-through columns

Christof Holliger, Julien Maillard, Emmanuelle Rohrbach, David Andrew Barry, Alessandro Brovelli, Elsa Marina Lacroix

The long-term buffering potential of three silicate minerals (diopside, fayalite and forsterite) present as fine particles in porous quartz sand medium was evaluated in flow-through column experiments over a period of 6.5 months. The columns were operated ...

Diversity of cobalamin riboswitches in the corrinoid-producing organohalide respirer Desulfitobacterium hafniense

Christof Holliger, Julien Maillard, Emmanuelle Rohrbach, Aurélie Duret

The strategic adaptation of prokaryotes in polluted niches involves the efficient regulation of their metabolism. The obligate anaerobe and metabolically versatile Desulfitobacterium hafniense reductively dechlorinates halogenated organic compounds (so-cal ...

An unusual tandem-domain rhodanese harbouring two active sites identified in Desulfitobacterium hafniense

Christof Holliger, Julien Maillard, Emmanuelle Rohrbach, Laure Prat

The rhodanese protein domain is common throughout all kingdoms of life and is characterized by an active site cysteine residue that is able to bind sulfane sulfur and catalyse sulfur transfer. No unique function has been attributed to rhodanese-domain-cont ...

Reductive dechlorination of tetrachloroethene by a stepwise catalysis of different organohalide respiring bacteria and reductive dehalogenases

Christof Holliger, Katia Szynalski, Julien Maillard, Emmanuelle Rohrbach, Pierre Rossi

The enrichment culture SL2 dechlorinating tetrachloroethene (PCE) to ethene with strong trichloroethene (TCE) accumulation prior to cis-1,2-dichloroethene (cis-DCE) formation was analyzed for the presence of organohalide respiring bacteria and reductive de ...

Performance and microbial community composition dynamics of aerobic granular sludge from sequencing batch bubble column reactors operated at 20, 30, and 35°

Christof Holliger, Julien Maillard, Emmanuelle Rohrbach, Sébastien Gabus, Pierre Rossi, Sirous Ebrahimi, Maryam Hosseini

Two bubble column sequencing batch reactors fed with an artificial wastewater were operated at 20, 30 and 35°C. In a first stage, stable granules were obtained at 20°C whereas fluffy structures were observed at 30°C. Molecular analysis revealed high abunda ...

Statistical Assessment of Variability of Terminal Restriction Fragment Length Polymorphism Analysis Applied to Complex Microbial Communities

Christof Holliger, Emmanuelle Rohrbach, François Gillet, Nouhou Diaby, Pierre Rossi

The variability of terminal restriction fragment polymorphism analysis applied to complex microbial communities was assessed statistically. Recent technological improvements were implemented in the successive steps of the procedure, resulting in a standard ...
