Resolving biodegradation patterns of persistent saturated hydrocarbons in weathered oil samples from the Deepwater Horizon disaster

Biodegradation plays a major role in the natural attenuation of oil spills. However, limited information is available about biodegradation of different saturated hydrocarbon classes in surface environments, despite that oils are composed mostly of saturate ...

Assessment of bioremediation potential and monitoring of biological reductive dechlorination in sites contaminated with chlorinated ethenes

Christof Holliger, Pierre Rossi, Sonia Estelle Tarnawski

Chlorinated ethenes (CEs), such as perchloroethene (PCE) and trichloroethene (TCE), are one of the most common class of groundwater contaminants. Aquifers are considered nowadays as dynamic ecosystems, showing multiple interactions between the physical, ch ...

Assessing the Bacterial Ecology of Organohalide Respiration for the Design of Bioremediation Strategies

Noam Shani

Groundwater is essential for human activities and is sometimes referred to as a non-renewable resource in the same way as oil and gas. During the past century, precious groundwater reserves worldwide have been threatened by anthropogenic release of chemica ...

Chitin colonization, chitin degradation and chitin-induced natural competence of Vibrio cholerae are subject to catabolite repression

Melanie Blokesch

Although Vibrio cholerae is a human pathogen its primary habitat are aquatic environments. In this environment, V. cholerae takes advantage of the abundance of zooplankton, whose chitinous exoskeletons provide a nutritious surface. Chitin also induces the ...

Development of bioreporter assays for the detection of bioavailability of long chain alkanes based on the marine bacterium Alcanivorax borkumensis strain SK2

Jeremy Samuel Arey, Rebecca Rutler

Long-chain alkanes are a major component of crude oil and therefore potentially good indicators of hydrocarbon spills. Here we present a set of new bacterial bioreporters and assays that allow to detect long-chain alkanes. These reporters are based on the ...

The genome of the Gram-positive, metal- and sulfate-reducing bacterium Desulfotomaculum reducens strain MI-1

Rizlan Bernier-Latmani, Thomas Junier, Nicholas Wigginton

P>Spore-forming, Gram-positive sulfate-reducing bacteria (SRB) represent a group of SRB that dominates the deep subsurface as well as niches in which resistance to oxygen and dessication is an advantage. Desulfotomaculum reducens strain MI-1 is one of the ...

Identification and characterization of proteins supporting dehalorespiration in Desulfitobacterium hafniense strain TCE1

Laure Prat

Respiration is a fundamental catalytic process in the aerobic and anaerobic energy metabolism of many prokaryotic and most eukaryotic organisms. The major difference between these organisms is that various organic and inorganic substrates can be used to do ...

BIOGEOGRAPHY AND SPATIAL VARIABILITY OF BACTERIAL COMMUNITIES ASSOCIATED WITH CHLOROETHENE – CONTAMINATED AQUIFERS

Christof Holliger, Pierre Rossi, François Gillet, Noam Shani

Numerous industries and facilities have been using chlorinated ethenes (CEs) as non-flammable solvents since the beginning of the 20th century. These compounds are known to persist in the environment, exerting adverse effects. They have been considered for ...

Electrokinetic transport of PAH-degrading bacteria in model aquifers and soil

An investigation of the mobility, viability, and activity of polycyclic aromatic hydrocarbon (PAH) degrading bacteria in an electric field is presented. Bench-scale model aquifers were used to test electrophoresis and electroosmosis as potential mechanisms ...

Assessment of microbial community changes and limiting factors during bioremediation of hydrocarbon-polluted soil with new miniaturized physiological methods

Karin Kaufmann

Due to human activities, organic pollutants are spilled to the environment where they threaten public health, often as contaminants of soil or groundwater. Living organisms are able to transform or mineralize many organic pollutants, and bioremediation tec ...
