Identification of parameters affecting the outcome of biochemical methane potential (BMP) tests

Anaerobic digestion of organic waste to methane gas (CH4) is an attractive method to produce renewable energy. Due to the trend towards the reuse of waste and away from fossil energy sources, this technology saw a worldwide development in the recent years. ...

Inoculum origin and adaptation had no influence on biomethane potential results with different substrates

Christof Holliger, Marc Deront, Nathalie Bachmann

Biomethane potential (BMP) tests are a valuable tool to design different parts of full-scale anaerobic digestion plants. Recent inter-laboratory studies have shown that the results of BMP tests can vary considerably and a comparison of BMP test norm protoc ...

Methane sources and sinks in Lake Kivu

Alfred Johny Wüest, Martin Schmid

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 ...

Survey of one-carbon metabolism in Desulfitobacteria

Christof Holliger, Julien Maillard, Laure Prat

Desulfitobacterium is a Gram-positive obligate anaerobic bacterium affiliated to the Firmicutes with a highly versatile carbon and energy metabolism. Increasing interest in this genus came with its involvement in the degradation of chlorinated compounds us ...

Discovery and Analysis of Novel Metabolic Pathways for the Biosynthesis of Industrial Chemicals: 3-Hydroxypropanoate

Vassily Hatzimanikatis

Sustainable microbial production of high-value organic compounds such as 3-hydroxypropanoate (3HP) is becoming an increasingly attractive alternative to organic syntheses that utilize petrochemical feedstocks. We applied the Biochemical Network Integrated ...

Study of the microbial communities of core and water samples in a chloroethenes contaminated aquifer

Guillaume Laulan

Widely used in industrial activities, chloroethenes have become common groundwater contaminants. Dehalorespiration is an anaerobic bacterial respiration coupling their sequential degradation to energy production. The interactions between the dehalorespirin ...

The impact of Co and Ni speciation on methanogenesis in sulfidic media - Biouptake versus metal dissolution

Graciela Gonzalez Gil

The speciation of the trace nutrients Co(II) and Ni(II) in sulfide containing media can control the methanogenic activity of Methanosarcina sp., which is of importance for the optimisation of anaerobic treatment of wastewater containing methanol. To obtain ...

Aerobic granular sludge reactor technology Microbial diversity of aerobic granules

David Gregory Weissbrodt

• Goal The goal of the project was to produce biomolecular fingerprints in order to describe the structure of microbial community which develops during aerobic sludge granulation, initiated in sequencing batch wastewater treatment processes. Four SBR were ...

Assessing Model Complexity from Anaerobic Digestion Data: When is Model AM1 Required?

Benoît Chachuat, Olivier Bernard

The anaerobic digestion ecosystem is complex, involving a broad variety of substrates and up to 140 bacterial species. This paper applies a methodology that determines the least number of macroscopic bioreactions to be taken into account in order to explai ...

Planar and Tubular perovskite-type membrane reactors for the partial oxidation of methane to syngas

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Joseph Sfeir

Dense planar and tubular oxygen separation membranes of La 0.6Ca0.4Fe0.75Co0.25O3-d were investigated as reactors for the partial oxidation (POX) of methane to syngas. Disk-shaped membranes were prepared by compaction and tubes by extrusion. Their permeati ...
