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

Christof Holliger, Pierre Rossi, Emmanuelle Rohrbach, Nouhou Diaby

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 ...

Towards a kinetic model of the phospholipids biosynthesis of the yeast Saccharomyces cerevisiae

Vassily Hatzimanikatis, Meriç Ataman, Georgios Savoglidis, Iro Oikonomidi

Lipids, as vital eukaryotic cellular components, play a major role in cell, tissue and organ physiology. Alterations of lipid enzymes and metabolic pathways are related to many human diseases, such as cancer, diabetes and neurodegenerative diseases. In thi ...

Functional diversity of reductive dehalogenases in a bacterial consortium degrading chloroethenes

Christof Holliger, Julien Maillard, Géraldine Florence Buttet, Sébastien Keller

Chlorinated hydrocarbon pollution threatens nature and human health due to its toxic and carcinogenic potential. Enrichment cultures were investigated for the bioremediation potential of tetrachloroethene (PCE). This process is based on bacterial anaerobic ...

Nitrogen Removal over Nitrite by Aeration Control in Aerobic Granular Sludge Sequencing Batch Reactors

Christof Holliger, Julien Maillard, Samuel Lochmatter

This study investigated the potential of aeration control for the achievement of N-removal over nitrite with aerobic granular sludge in sequencing batch reactors. N-removal over nitrite requires less COD, which is particularly interesting if COD is the lim ...

Methane Reacts with Heteropolyacids Chemisorbed on Silica to Produce Acetic Acid under Soft Conditions

David Lyndon Emsley, Aaron James Rossini, Jeremie Pelletier

Selective functionalization of methane at moderate temperature is of crucial economic, environmental, and scientific importance. Here, we report that methane reacts with heteropolyacids (HPAs) chemisorbed on silica to produce acetic acid under soft conditi ...

Optimization of Reactor Startup and Nitrogen Removal of Aerobic Granular Sludge Systems

Samuel Lochmatter

Aerobic granular sludge (AGS) in sequencing batch reactors (SBR) has recently made its proofs as full-scale technology for the biological treatment of urban wastewater. In contrast to conventional flocculent activated sludge, microorganisms aggregate to de ...

Above- and below-ground methane fluxes and methanotrophic activity in a landfill-cover soil

Graciela Gonzalez Gil

Landfills are a major anthropogenic source of the greenhouse gas methane (CH4). However, much of the CH4 produced during the anaerobic degradation of organic waste is consumed by methanotrophic micro-organisms during passage through the landfill-cover soil ...

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 ...

Phylogenetic and functional marker genes to study ammonia-oxidizing microorganisms (AOM) in the environment

Thomas Junier

The oxidation of ammonia plays a significant role in the transformation of fixed nitrogen in the global nitrogen cycle. Autotrophic ammonia oxidation is known in three groups of microorganisms. Aerobic ammonia-oxidizing bacteria and archaea convert ammonia ...

Methane- and ammonia-oxidizing bacteria at the chemocline of Lake Kinneret (Israel)

The vertical distribution of methane- and ammonia-oxidizing bacteria (MOB and AOB, respectively), and the physicochemical conditions in the chemocline of Lake Kinneret (Israel) were studied at a resolution of 10 cm from 16.2 to 17.7 m depth. Profiles of th ...
