NanoSIMS isotopic imaging - Deciphering the nature of coral-symbiont metabolic interactions

Anders Meibom, Isabelle Domart-Coulon, Christophe Kopp, Thomas Krüger, Maoz Fine

The ability of endosymbiotic Symbiodinium to fix inorganic nutrients and their translocation to the coral host is considered a key element for the growth of coral reefs in tropical coastal waters and has been a fundamental research topic for over 50 years. ...

Organic nitrate aerosol formation via NO3 + biogenic volatile organic compounds in the southeastern United States

Satoshi Takahama, Christine Mohr

Gas- and aerosol-phase measurements of oxidants, biogenic volatile organic compounds (BVOCs) and organic nitrates made during the Southern Oxidant and Aerosol Study (SOAS campaign, Summer 2013) in central Alabama show that a nitrate radical (NO3) reaction ...

Methane oxidation pathways in Lake La Cruz

Corinne Jegge

Even though lakes only occupy a small percentage of Earth's surface, they represent a natural source of methane, contributing substantially to methane emissions and ultimately to global warming. There is extensive evidence that methane emissions from lakes ...

Wastewater treatment processes modelling for anaerobic digestion effluents

Miriel Steudler

The general topic of this research project is the modelling of wastewater treatment processes for anaerobic digestion effluents, which are characterized by high nitrogen concentrations. In order to avoid eutrophication of lakes and rivers caused by nutrien ...

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 ...

Do peatlands hibernate?

Alexandre Buttler, Vincent Eric Jules Jassey, Constant Signarbieux, Robert Thomas Edmund Mills

Winter seasonality with low amounts of incoming radiation, frost and snow cover characterize large areas at mid- and high latitudes, especially in the arctic and in mountain ranges. Because of these adverse conditions, it is often assumed that ecosystem pr ...

A Fast and Selective Near-Infrared Fluorescent Sensor for Multicolor Imaging of Biological Nitroxyl (HNO)

Pablo Rivera Fuentes

The first near-IR fluorescent turn-on sensor for the detection of nitroxyl (HNO), the one-electron reduced form of nitric oxide (NO), is reported. The new copper-based probe, CuDHX1, contains a dihydroxanthene (DHX) fluorophore and a cyclam deriv. as a Cu( ...

Microbial diversity differences within aerobic granular sludge and activated sludge flocs

In this study, we investigated during 400 days the microbial community variations as observed from 16S DNA gene DGGE banding patterns from an aerobic granular sludge pilot plant as well as the from a full-scale activated sludge treatment plant in Epe, the ...

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 ...

Optimized aeration strategies for nitrogen and phosphorus removal with aerobic granular sludge

Christof Holliger, Samuel Lochmatter, Graciela Gonzalez Gil

Biological wastewater treatment by aerobic granular sludge biofilms offers the possibility to combine carbon (COD), nitrogen (N) and phosphorus (P) removal in a single reactor. Since denitrification can be affected by suboptimal dissolved oxygen concentrat ...
