Influence of Microplastics on Microbial Structure, Function, and Mechanical Properties of Stream Periphyton

Kristin Schirmer, Ahmed Tlili, Renata Behra

Periphyton is a freshwater biofilm composed of prokaryotic and eukaryotic communities that occupy rocks and sediments, forming the base of the food web and playing a key role in nutrient cycling. Given the large surface that periphyton comprises, it may al ...

Impact of wastewater on the microbial diversity of periphyton and its tolerance to micropollutants in an engineered flow-through channel system

Kristin Schirmer, Ahmed Tlili

Wastewater treatment plants (WWTPs) play an important role in retaining organic matter and nutrients but to a lesser extent micropollutants. Therefore, treated wastewater is recognized as a major source of multiple stressors, including complex mixtures of ...

Silver Nanoparticle Effects on Stream Periphyton During Short-Term Exposures

Kristin Schirmer, Ahmed Tlili, Renata Behra

Silver nanoparticles (AgNP) are increasingly used as antimicrobials in consumer products. Subsequently released into aquatic environments, they are likely to come in contact with microbial communities like periphyton, which plays a key role as a primary pr ...

Optofluidic microdevice for algae classification: a comparison of results from discriminant analysis and neural network pattern recognition

Yves Bellouard

The early detection of changes in the level and composition of algae is essential for tracking water quality and environmental changes. Current approaches require the collection of a specimen which is later analyzed in a laboratory: this slow and expensive ...
