Methane sources and sinks in Lake Kivu

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 ...

Faster and Smoother - VSH Revisited

Juraj Sarinay

We reconsider the provably collision resistant Very Smooth Hash and propose a small change in the design aiming to improve both performance and security. While the original proofs of security based on hardness of factoring or discrete logarithms are preser ...

Microbial diversity of aerobic granular sludge: Is it different from activated sludge?

David Gregory Weissbrodt

This common presentation was given within the Aerobic Granular Sludge Workshop organized during the IWA Biofilm Conference 2011 (Shanghai, China). The aim was to bring the state-of-the-art knowledge on the microbial diversity present in aerobic granular sl ...

Purification & characterization of PceC protein involved in dehalorespiration by desulfitobacterium & dehalobacter

Christof Holliger, Julien Maillard, Aamani Rupakula Boyanapalli

Dehalorespiration is a process during which microbes derive energy by the reductive dehalogenation of chlorinated organic pollutants, by using them as electron acceptors. Characterization of the full dehalorespiration pathway in dehalogenating organisms is ...

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 ...

MICROBIAL AND BIOMOLECULAR HETEROGENEITY OF AEROBIC GRANULES WITHIN A SINGLE BIOREACTOR ?

David Gregory Weissbrodt, Samuel Lochmatter

Aerobic granulation is considered as a promising alternative to conventional activated sludge in biological wastewater treatment. Instead of forming flocs the bacterial communities aggregate to dense granular biofilms. In the present study, granules were c ...

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 ...

Oxygen and proton reduction by decamethylferrocene in non-aqueous acidic media

Hubert Girault, Manuel Alejandro Méndez Agudelo, Bin Su, Peiyu Ge, Imren Hatay, Zdenek Samec

Experimental studies and density functional theory (DFT) computations suggest that oxygen and proton reduction by decamethylferrocene (DMFc) in 1,2-dichloroethane involves protonated DMFc, DMFcH+, as an active intermediate species, producing hydrogen perox ...

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 ...

Advantages and limits of co-digestion in wastewater treatment plants – comparison to co-digestion in agriculture

Nathalie Bachmann

The Master Project offers a survey on several aspects of co-digestion in wastewater treatment plants (WWTP) and in agriculture. The description of the legal context and the technical processes present the basis for the subsequent analysis of the co-digesti ...
