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 ...

Cutover peatland regeneration assessment using organic matter and microbial indicators (bacteria and testate amoebae)

Alexandre Buttler, Edward Mitchell

Cutover peatlands cover large surfaces of high potential value for biodiversity and carbon sequestration function if successfully restored but the evaluation of restoration success is not straighforward. We assessed the bioindicator value of organic mat ...

Linking chemical speciation to metal bioavailability

Cristina Lamelas

It is recognized that dissolved organic matter (DOM) plays an utmost role in aquatic ecosystems by binding trace metals and influencing their speciation, bioavailability and detrimental effects. DOM is considered to protect the aquatic microorganisms from ...

Effects of aqueous organosulfur chemistry on particulate methanesulfonate to non-sea salt sulfate ratios in the marine atmosphere

Athanasios Nenes

The oxidation of dimethyl sulfide (DMS, CH3SCH3) in the atmosphere could influence climate by affecting cloud condensation nuclei concentrations and cloud properties. This work focuses on elucidating the importance of DMS-cloud intera ...

Coupling between land ecosystems and the atmospheric hydrologic cycle through biogenic aerosol pathways

Athanasios Nenes

Important land surface characteristics affect the way in which water is transferred to the atmosphere, processed in the atmosphere, and eventually returned to the surface. In turn, the amount of water in the atmosphere and returning to Earth affects many o ...

Acoustic observations of zooplankton in lakes using a Doppler current profiler

Alfred Johny Wüest

In this paper we test the usefulness of acoustic backscatter measurements from a 614 kHz Acoustic Doppler Current Profiler (ADCP) for the qualitative and quantitative characterisation of zooplankton distributions in lakes. ADCP-based backscatter estimat ...

Structure of microbial communities in Sphagnum peatlands and effect of atmospheric carbon dioxide enrichment

Alexandre Buttler, Edward Mitchell, Jean-Michel Gobat

Little is known about the structure of microbial communities in Sphagnum peatlands, and the potential effects of the increasing atmospheric CO2 concentration on these communities are not known. We analyzed the structure of microbial communities in five Sph ...
