DENITRIFYING PAO AND GAO IN AEROBIC GRANULAR BIOFILM CULTIVATED WITH ACETATE AND PROPIONATE

Christof Holliger, David Gregory Weissbrodt, Samuel Lochmatter, Graciela Gonzalez Gil

Phosphate accumulating organisms (PAO) and glycogen accumulating organisms (GAO) play an important role in aerobic granular biofilm systems used for wastewater treatment. Both are slow growing organisms which can take up and store carbon under anaerobic co ...

The choice of inoculum is key for aerobic granular sludge process development

Christof Holliger, Pierre Rossi, Emmanuelle Rohrbach, David Gregory Weissbrodt, Samuel Lochmatter, Sirous Ebrahimi, Sébastien Gabus

The aerobic granular sludge process optimization is linked to the interdependence of process, biofilm and microbial scales. Stable dense fast-settling granules composed of bacterial guilds for the simultaneous removal of carbonaceous, phosphorous and nitro ...

Are Sphagnum-dominated regenerating cutover bogs C sinks or not? A study in the Swiss Jura Mountains with predictions of climate change impacts on the C balance

Alexandre Buttler, Edward Mitchell, Andy Siegenthaler

Growing peatlands are an important long-term carbon (C) sink and thus play a key role in the global C cycle. Vast surfaces of northern peatlands have been mined for peat and are currently abandoned. In these surfaces, secondary vegetation succession takes ...

Formation of assimilable organic carbon (AOC) and specific natural organic matter (NOM) fractions during ozonation of phytoplankton

Urs von Gunten, Thomas Egli

Ozonation of natural surface water increases the concentration of oxygen-containing low molecular weight compounds. Many of these compounds support microbiological growth and as such are termed assimilable organic carbon (AOC). Phytoplankton can contribute ...

Carbon storage on exposed continental shelves during the glacial-interglacial transition

Jed Oliver Kaplan

We present analyses of new and previously published estimates of total (vegetation plus soil) carbon storage on exposed continental shelves during the LGM. Carbon stock estimates from environmental reconstructions vary from 113 to 202 Pg C. Estimates from ...

Nitrogen and Sulphur Deposition on regional and global scales: a multi-model evaluation

We use 23 atmospheric chemistry transport models to calculate current and future (2030) deposition of reactive nitrogen (NOy, NHx) and sulfate (SOx) to land and ocean surfaces. The models are driven by three emission scenarios: (1) current air quality legi ...

Long-term effects of short-term perturbation in a sub-alpine grassland

Thomas Spiegelberger

Theoretical advances and short-term experimental studies have furthered our understanding of how ecosystems respond to perturbation. However, there are few wellreplicated experimental studies that allow an assessment of long-term responses. Results from a ...

Exploitation of northern peatlands and biodiversity maintenance: a conflict between economy and ecology

Alexandre Buttler, Edward Mitchell

Peatlands are ecosystems of exceptional conservation value because of their beauty, biodiversity, importance in global geochemical cycles, and the paleoenvironmental records they preserve. Commercial extraction and drainage for forestry or agriculture have ...

Implications of coral reef buildup for the controls on atmospheric CO2 since the Last Glacial Maximum

Jed Oliver Kaplan

We examine the effect on atmospheric CO2 of the occurrence of increased shallow water carbonate deposition and regrowth of the terrestrial biosphere following the last glacial. We find that contrary to recent speculations that changes in terrestrial carbon ...

Climate and interannual variability of the atmosphere-biosphere 13CO2 flux

Jed Oliver Kaplan

We present a bottom-up approach to simulate the terrestrial isotopic carbon variations using the Lund-Potsdam-Jena dynamic global vegetation model (LPJ-DGVM). LPJ is extended to include isotopic fractionation of C-13 at the leaf level during assimilation a ...
