The cost of adaptability: resource availability constrains functional stability under pulsed disturbances

Global change exposes ecosystems to changes in the frequency, magnitude, and concomitancy of disturbances, which impact the composition and functioning of these systems. Here, we experimentally evaluate the effects of salinity disturbances and eutrophicati ...

Organohalide respiration: variations on a common theme

Christof Holliger, Julien Maillard, Mathilde Stéphanie Willemin, Lorenzo Cimmino

Organohalide respiration (OHR) is a bacterial anaerobic respiratory metabolism that makes use of halogenated organic compounds as terminal electron acceptors. While organohalogens have been initially thought to be mainly from anthropogenic origin, thousand ...

Hybrid Transcriptional Regulators for the Screening of Target DNA Motifs in Organohalide-Respiring Bacteria

Christof Holliger, Julien Maillard, Mathilde Stéphanie Willemin, Marie Vingerhoets

The bioremediation of persistent organohalide molecules under anoxic conditions mostly relies on the bacterial process called organohalide respiration (OHR). Organohalide-respiring bacteria (OHRB) are phylogenetically diverse anaerobic bacteria that share ...

Petrophysical properties of heavy oil-bearing carbonate rocks and their implications on petroleum system evolution: Insights from the Majella Massif

Carolina Giorgetti

In this work, we investigate the role of hydrocarbons in changing the petrophysical properties of rocks by merging laboratory measurements, outcrops characterization, and subsurface data focusing on a carbonate-bearing reservoir (Bolognano Formation) of th ...

Modeling metabolic networks of individual bacterial agents in heterogeneous and dynamic soil habitats (IndiMeSH)

Vassily Hatzimanikatis, Meriç Ataman, Dani Or

Natural soil is characterized as a complex habitat with patchy hydrated islands and spatially variable nutrients that is in a constant state of change due to wetting-drying dynamics. Soil microbial activity is often concentrated in sparsely distributed hot ...

Characterization of the predicted membrane anchor of reductive dehalogenases

Julien Maillard, Lorenzo Cimmino, Marie Joanna Marie-Joseph Dannay

BACKGROUND Organohalide respiration (OHR) is a metabolic process that couples the reduction of halogenated organic compounds to energy conservation in a few phylogenetically diverse anaerobic bacteria. In this study, tetrachloroethene (= perchloroethene, P ...

Comprehensive review on toxicity of persistent organic pollutants from petroleum refinery waste and their degradation by microorganisms

Edgard Gnansounou

Control and prevention of environmental pollution has become a worldwide issue of concern. Aromatic hydrocarbons including benzene, toluene, ethyl benzene, xylene (BTEX) and polyaromatic hydrocarbons (PAHs) are persistent organic pollutants (POPs), release ...

Mycobacterium tuberculosis Resists Stress by Regulating PE19 Expression

John McKinney, Anna De Graff Tischler

Mycobacterium tuberculosis requires the phosphate-sensing signal transduction system Pst/SenX3-RegX3 to resist host immune responses. A Delta pstA1 mutant lacking a Pst phosphate uptake system component is hypersensitive to diverse stress conditions in vit ...

Divergent PCB organohalide-respiring consortia enriched from the efflux channel of a former Delor manufacturer in Eastern Europe

Christof Holliger, Pierre Rossi, Luiz Felippe De Alencastro, Martina Praveckova

Polychlorinated biphenyl (PCB) organohalide-respiring communities from the efflux channel of a former Delor manufacturer in Eastern Slovakia were assessed using metagenomic, statistical and cultivation-adapted approaches. Multivariate analysis of environme ...

On-site biostimulation evaluation of a remediated perchloroethene-contaminated acquifer located in Jablunkov, Czech Republic

Isabelle Fäh

Chlorinated ethenes solvents (CEs) are one of the most common contaminants identified in groundwater ecosystems. Long used as a degreaser in industry, perchloroethene (PCE) and trichloroethene (TCE) are particularly persistent in the environment as recalci ...
