Kurz1,2, Eleonora Secchi1, Roman Stocker1, Joaquin Jimenez-Martinez1,2 1Department of Civil, Environmental and Geomatic Engineering, Institute of Environmental Engineering, ETH Zurich, 2Department Water Resources and Drinking Water, Swiss Federal Institute of Aquatic Science and Technology The present protocol describes a microfluidic platform to study biofilm development in quasi-2D porous media by combining high-resolution microscopy imaging with simultaneous pressure difference measurements. The platform quantifies the influence of pore size and fluid flow rates in porous media on bioclogging. Environment Construction of a Low-cost Mobile Incubator for Field and Laboratory Use Ariane Schertenleib1, Jürg Sigrist2, Max N. D. Friedrich3, Christian Ebi4, Frederik Hammes2, Sara J. Marks1 1Department of Sanitation, Water & Solid Waste for Development, Swiss Federal Institute of Aquatic Science and Technology (Eawag), 2Department of Environmental Microbiology, Eawag, 3Department of Environmental Social Sciences, Eawag, 4Department of Urban Water Management, Eawag This paper describes a method for building an adaptable, low-cost and transportable incubator for microbial testing of drinking water. Our design is based on widely available materials and can operate under a range of field conditions, while still offering the advantages of higher-end laboratory-based models. Environment Characterization of Aquatic Biofilms with Flow Cytometry Linn Sgier1, Stephanie N. Merbt1, Ahmed Tlili1, Alexandra Kroll1, Anze Zupanic1 1Department of Environmental Toxicology, Eawag - Swiss Federal Institute for Aquatic Science and Technology Flow cytometry in combination with visual clustering offers an easy-to-use and fast method for studying aquatic biofilms. It can be used for biofilm characterization, detection of changes in biofilm community structure, and detection of abiotic particles embedded in the biofilm.
