Combined Earth observations reveal the sequence of conditions leading to a large algal bloom in Lake Geneva
Damien Bouffard, Abolfazl Irani Rahaghi, Oscar Rodrigo Sepúlveda Steiner, Rafael Sebastian Reiss, Marco Toffolon, Frédéric Charles Soulignac
Freshwater algae exhibit complex dynamics, particularly in meso-oligotrophic lakes with sudden and dramatic increases in algal biomass following long periods of low background concentration. While the fundamental prerequisites for algal blooms, namely ligh ...
Springernature2024Reactivity of Cyanobacteria Metabolites with Ozone: Multicompound Competition Kinetics
Cyanobacterial blooms occur at increasing frequency and intensity, notably in freshwater. This leads to the introduction of complex mixtures of their products, i.e., cyano-metabolites, to drinking water treatment plants. To assess the fate of cyano-metabol ...
Amer Chemical Soc2024Vertical distribution and seasonal dynamics of planktonic cyanobacteria communities in a water column of deep mesotrophic Lake Geneva
Tamar Kohn, Stéphane Joost, Anna Carratala Ripolles, Oliver Michele Selmoni, Charlotte Gisèle Weil, Hannah Elisa Chmiel, Annie Sandrine Guillaume, Coralie Chappelier
Background: Temperate subalpine lakes recovering from eutrophication in central Europe are experiencing harmful blooms due to the proliferation of Planktothrix rubescens, a potentially toxic cyanobacteria. To optimize the management of cyanobacteria blooms ...
2023Improving algal bloom detection using spectroscopic analysis and machine learning: A case study in a large artificial reservoir, South Korea
The prediction of algal blooms using traditional water quality indicators is expensive, labor-intensive, and timeconsuming, making it challenging to meet the critical requirement of timely monitoring for prompt management. Using optical measures for foreca ...
ELSEVIER2023Phototransformation kinetics of cyanobacterial toxins and secondary metabolites in surface waters
Background Cyanobacteria and their toxins occur in high concentrations during the so-called bloom events in surface waters. To be able to assess the risks associated with cyanobacterial blooms, we need to understand the persistence and fate processes of th ...
SPRINGER2021Inhibited vertical mixing and seasonal persistence of a thin cyanobacterial layer in a stratified lake
Alfred Johny Wüest, Damien Bouffard, Oscar Rodrigo Sepúlveda Steiner, Bieito Fernandez Castro
Harmful blooms of the filamentous cyanobacteria Planktothrix rubescens have become common in many lakes as they have recovered from eutrophication over the last decades. These cyanobacteria, capable of regulating their vertical position, often flourish at ...
2021Catalytic effects of photogenerated Fe(II) on the ligand-controlled dissolution of Iron(hydr)oxides by EDTA and DFOB
Low bioavailability of iron due to poor solubility of iron(hydr)oxides limits the growth of microorganisms and plants in soils and aquatic environments. Previous studies described accelerated dissolution of iron(hydr)oxides under continuous illumination, b ...
PERGAMON-ELSEVIER SCIENCE LTD2021Biotechnology Applications of Nanocarbons in Plant and Algal Systems
Ardemis Anoush Boghossian, Alice Judith Gillen, Alessandra Antonucci
The unique combination of structural, optical, and electronic properties of nanocarbons (NCs) has made these materials particularly attractive for various applications in biotechnology and biomedicine, ranging from sensing, gene-delivery, bioimaging and th ...
Royal Society of Chemistry2021Interaction of Fluorescent Single-Walled Carbon Nanotubes with Photosynthetic Microbes
The discovery of carbon-based nanomaterials has impacted a variety of research areas in ways that could not be imagined three decades ago. Their unique combination of structural, optical, and electronic properties has made these nano-sized materials partic ...
EPFL2020Thin layers of phytoplankton and harmful algae events in a coastal upwelling system
We combined time-series from a monitoring program and specific field observations in order to: 1) describe the characteristics of thin layers of phytoplankton (TLP) in the Galician Rías Baixas (NW Iberian Peninsula), 2) investigate the relationship between ...
