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 ...

Culture based approaches, dependent and independent, for microbial community fractions in petroleum oil reservoirs

Edgard Gnansounou

Petroleum reservoir is an ecosystem having extreme environmental conditions of temperature, pressure and salinity. They possess highly anoxic conditions. Major microbial communities present in this environment include fermentative bacteria, sulphate reduci ...

Indirect Evidence Link PCB Dehalogenation with Geobacteraceae in Anaerobic Sediment-Free Microcosms

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

Although polychlorinated biphenyls (PCBs) production was brought to a halt 30 years ago, recalcitrance to degradation makes them a major environmental pollutant at a global scale. Previous studies confirmed that organohalide-respiring bacteria (OHRB) were ...

Indirect evidences for PCB congener degradation by Geobacteraceae in anaerobic sediment-free microcosms

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

Although PCBs production was brought to a halt thirty years ago, recalcitrance to degradation makes them a major environmental pollutant. Previous studies confirmed that organohalide-respiring bacteria (OHRB) were capable of utilizing chlorinated congeners ...

Iron-oxides and iron-citrate as new photocatalysts in solar inactivation of Escherichia coli in water

Cristina del Socorro Lonfat

This study addresses the bacterial inactivation mechanism by photo-Fenton process at near-neutral pH, focusing on iron-oxides and iron-citrate as photocatalysts for solar water disinfection and using E. coli as a bacteria model. Cell envelope damage during ...

Extracellular polymeric substances affecting pore-scale hydrologic conditions for bacterial activity in unsaturated soils

Dani Or

Soil bacterial cells are often found embedded in biosynthesized extracellular polymeric substances ( EPS) forming aggregates or stationary colonies attached to solid surfaces. Soil bacterial aggregation and pooling of resources offer a successful adaptatio ...

A Comparison of Solar Photocatalytic Inactivation of Waterborne E. Coli Using Tris(2,2’-bipyridine)ruthenium(II), Rose Bengal and TiO2

César Pulgarin, Julian Andrés Rengifo Herrera

Background. The development of alternative processes to eliminate pathogenic agents in water is a matter of growing interest. Current drinking water disinfection procedures, such as chlorination and ozonation, can generate disinfection by-products with car ...

Stealth proteins: in silico identification of a novel protein family rendering bacterial pathogens invisible to host immune defense

Philipp Bucher

There are a variety of bacterial defense strategies to survive in a hostile environment. Generation of extracellular polysaccharides has proved to be a simple but effective strategy against the host's innate immune system. A comparative genomics approach l ...

Ultrasensitive reporter protein detection in genetically engineered bacteria

Theo Lasser

We demonstrate the use of laser-induced. fluorescence confocal spectroscopy to measure analyte-stimulated enhanced green fluorescent protein (egfp) synthesis by genetically modified Escherichia coli bioreporter cells. Induction is measured in cell lysates ...

Rafts can trigger contact-mediated secretion of bacterial effectors via a lipid-based mechanism

Françoise Gisou van der Goot Grunberg

Infection by the Gram-negative bacterial pathogen Shigella flexneri depends on its ability to invade host cells. Bacterial engulfment requires a functional type III secretion system (TTSS) allowing the translocation into host cells of bacterial effectors t ...
