Inoculum origin and adaptation had no influence on biomethane potential results with different substrates

Christof Holliger, Marc Deront, Nathalie Bachmann

Biomethane potential (BMP) tests are a valuable tool to design different parts of full-scale anaerobic digestion plants. Recent inter-laboratory studies have shown that the results of BMP tests can vary considerably and a comparison of BMP test norm protoc ...

Methane sources and sinks in Lake Kivu

Alfred Johny Wüest, Martin Schmid

Unique worldwide, Lake Kivu stores enormous amounts of CH4 and CO2. A recent study reported that CH4 concentrations in the lake have increased by up to 15% in the last 30 years and that accumulation at this rate could lead to catastrophic outgassing by sim ...

Characterization of Groundwater Microbial Communities, Dechlorinating Bacteria, and In Situ Biodegradation of Chloroethenes Along a Vertical Gradient

Pierre Rossi, Noam Shani

The variability of hydrogeochemical conditions can affect groundwater microbial communities and the natural attenuation of organic chemicals in contaminated aquifers. It is suspected that in situ biodegradation in anoxic plumes of chloroethenes depends on ...

Ecological Controls of Aerobic and Anaerobic Microbial Activities and Potential Impacts on Greenhouse Gases in Regenerating Peatlands

Andy Siegenthaler

Peatlands represent massive global carbon (C) pools and sinks. Carbon accumulation depends on the ratio between net primary production and decomposition of organic matter, both of which can change under projected increases of atmospheric carbon dioxide (CO ...

Modeling the effectiveness of U(VI) biomineralization in dual porosity porous media

David Andrew Barry

Recent attention has focused on the in situ immobilization of uranium by stimulation of dissimilatory metal-reducing bacteria (DMRB). The objective of this work was to investigate the effectiveness of this approach in heterogeneous and structured porous me ...

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, Pierre Rossi, Emmanuelle Rohrbach, Sirous Ebrahimi, Sébastien Gabus, 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 ...

Influence of temperature and high acetate concentrations on methanogenensis in lake sediment slurries

Christof Holliger, Bernhard Wehrli

Methanogenesis from main methane precursors H2/CO2 and acetate was investigated in a temperature range of 2–70 °C using sediments from Lake Baldegg, Switzerland. Psychrophilic, psychrotrophic, mesophilic, and thermophilic methanogenic microbial communities ...

Marine isotope stage (MIS) 8 millennial variability stratigraphically identical to MIS 3

Jérôme Chappellaz

We have performed the first ever combined-element stable isotopic measurements of extraterrestrial molecules. Methane from two carbonaceous chondrites, Murchison and Cold Bokkeveld, was measured for its hydrogen and carbon isotopic compositions. The combin ...

Bile acids induce energy expenditure by promoting intracellular thyroid hormone activation

Johan Auwerx, Kristina Schoonjans, Chikage Mataki

While bile acids (BAs) have long been known to be essential in dietary lipid absorption and cholesterol catabolism, in recent years an important role for BAs as signalling molecules has emerged. BAs activate mitogen-activated protein kinase pathways, are l ...
