Multiple-endpoint assay provides a detailed mechanistic view of responses to herbicide exposure in Chlamydomonas reinhardtii

The release of herbicides into the aquatic environment raises concerns about potential detrimental effects on ecologically important non-target species, such as unicellular algae, necessitating ecotoxicological risk assessment. Algal toxicity tests based o ...

Esfenvalerate toxicity to the cladoceran Ceriodaphnia dubia in the presence of green algae, Pseudokirchneriella subcapitata

The presence of phytoplankton, like other particulate organic matter, can interfere with the effects of hydrophobic contaminants such as pyrethroid pesticides. However, the reduction or elimination of toxicity by algae added as food during testing is not t ...

Development of a microalgal process for bioenergy production, CO2 mitigation and wastewater treatment

Christof Holliger, Jean-Paul Schwitzguebel, Gabrielle Hack, Charlotte Pfistner

Over the last decade, intensive research has been carried out all over the world to explore the huge potential of microalgae for biofuel production, which could be coupled to the use of industrial flue gas to enhance CO2 fixation as a greenhouse gas mitiga ...

Towards the sustainable cultivation of microalgae for the production of biofuels and added-value chemicals

Christof Holliger, Jean-Paul Schwitzguebel, Gabrielle Hack, Charlotte Pfistner

Microalgae represent an attractive source of biomass for biofuels 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 brackish water. Their use ...

Optofluidic lab-on-a-chip for rapid algae population screening

Yves Bellouard

The rapid identification of algae species is not only of practical importance when monitoring unwanted adverse effects such as eutrophication, but also when assessing the water quality of watersheds. Here, we demonstrate a lab-on-a-chip that functions as a ...

Catalytic gasification of algae in supercritical water for biofuel production and carbon capture

Christian Ludwig, Frédéric Vogel, Martin Brandenberger

There has been growing concern about the way cultivating biomass for the production of agro-biofuels competes with food production. To avoid this competition biomass production for biofuels will, in the long term, have to be completely decoupled from food ...

No Evidence for the Induction of Brown Algal Chemical Defense by the Phytohormones Jasmonic Acid and Methyl Jasmonate

Induced chemical defense reactions are widespread in marine brown algae. Despite the evidence that the biosynthesis of defense metabolites can be up-regulated upon herbivory, we do not know how this regulation of biosynthetic pathways to secondary metaboli ...

To live and let die in The Big Blue

Karl Gademann

Harmful algal blooms in both freshwater and marine environments pose significant challenges for humans, livestock and aquatic food webs. Over the last 50 years, several authors proposed that small mol. iron chelators (siderophores) could be responsible for ...

Comparison of Cd(II), Cu(II) and Pb(II) Biouptake by Green Algae in the Presence of Humic Acid

Cristina Lamelas

The present study examines the role of humic acid, as a representative of dissolved organic matter, in Cd(II), Cu(II) and Pb(II) speciation and biouptake by green microalgae. Cellular and intracellular metal fractions were compared in the presence of citri ...
