Biofuel production from microalgae by hydrothermal processing

Christian Ludwig, Rizlan Bernier-Latmani, Frédéric Vogel, Jean-Paul Schwitzguebel, Gabriela Anca Haiduc

Introduction: Microalgae cultures represent an attractive source of biomass for biofuel and chemicals production since they can have higher energy yields per area than conventional biomass crops and can be grown on marginal land using waste, saline, or bra ...

Dynamic NanoSIMS ion imaging of unicellular freshwater algae exposed to copper

This work demonstrates the capabilities of nanoscale secondary-ion mass spectrometry, using the Cameca NanoSIMS50 ion microprobe, to detect and image the copper-ion distribution in microalgal cells exposed to nanomolar and micromolar copper concentrations. ...

Occurrence of dissolved and particle-bound taste and odor compounds in Swiss lake waters

Urs von Gunten

The occurrence of algal taste and odor (T&O) compounds was investigated in three Swiss lakes which exhibit different nutrient levels from eutrophic to oligotrophic (Lake Greifensee, Lake Zurich and Lake Lucerne). Apart from dissolved T&O compounds, the stu ...

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 ...

Sawdust addition reduces the productivity of nitrogen-enriched mountain grasslands

Thomas Spiegelberger

Anthropogenic nutrient enrichment of mountain grasslands has boosted grasses and fast-growing unpalatable plants at the expense of slow-growing species, resulting in a significant loss in biodiversity. A potential tool to reduce nutrient availability and a ...

Regulation of Episomal Gene Expression by KRAB/KAP1-Mediated Histone Modifications

Didier Trono, Patrick Aebischer, Isabelle Barde, Sonia Verp, Vivianne Padrun, Christopher Towne, Anna Claire Groner

KAP1 is an essential cofactor of KRAB zinc finger proteins, a family of vertebrate-specific epigenetic repressors of largely unknown functions encoded in the hundreds by the mouse and human genomes. So far, KRAB/KAP1-mediated gene regulation has been studi ...

Testate amoebae analysis in ecological and paleoecological studies of wetlands: past, present and future

Edward Mitchell

Testate amoebae are an abundant and diverse polyphyletic group of shelled protozoa living in aquatic to moist habitats ranging from estuaries to lakes, rivers, wetlands, soils, litter, and moss habitats. Owing to the preservation of shells in sediments, te ...

Quantitative characterization of a recombinant Pichia pastoris Mut+ strain secreting avidin using transient continuous cultures

Carmen Jungo

The objective of this thesis was to characterize the growth stoichiometry, the specific recombinant protein productivity and the regulation of the alcohol oxidase (AOX) enzyme of a Pichia pastoris Mut+ strain, performing conventional chemostat cultures and ...

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 ...
