New antiplasmodial natural products from cyanobacteria: linking their ecological role to their therapeutic potential

Karl Gademann, Cyril Portmann

Cyanobacteria (blue-green algae) produce many metabolites that are directed towards competing photoautotrophs. Such algicidal compounds might offer new approaches for the selective inhibition of the malaria parasite, Plasmodium falciparum, as this organism ...

Dynamic NanoSIMS ion imaging of unicellular freshwater algae exposed to copper

Vera Slaveykova-Startcheva

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. ...

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 ...

Cyanobacterial Natural Products for the Inhibition of Biofilm Formation and Biofouling

Karl Gademann

Biofouling is defined by the non-specific attachment of biological material (proteins, carbohydrates, prokaryotic cells and higher organisms) to surfaces upon their exposure to any biological fluid. Biofouling is a serious problem in many areas ranging fro ...

Effects of experimental lead pollution on the microbial communities associated to Sphagnum fallax (Bryophyta)

Ecotoxicological studies usually focus on single microbial species under controlled conditions. As a result, little is known about the responses of different microbial functional groups or individual species to stresses. In an aim to assess the response of ...
