Standard presentation:

1st price (1000€) : Stefan Lips for his presentation on “How to anchor metabolic responses of microbial communities to community functioning?

Stefan Lips

  • Status: PhD student (>3 Year)
  • Lab: Department Bioanalytische Ökotoxikologie, Helmholtz-Zentrum für Umweltforschung – UFZ, Leipzig, Germany
  • About me and my research: During my bachelor I realised that every product finally ends up in the water, but there was nobody who knew for certain whether this has an effect on the ecosystem. This realization paved my way to the field of ecotoxicology. Nowadays I am working on the effects of chemicals on microorganism communities and their function in the ecosystem.

2nd price (800€) : Laurianne Paris for her presentation on “Metabolic response of Microbacterium sp. C448 exposed to environmental and medicinal concentrations of sulfamethazine antibiotic


  • Status: post doc
  • Labs: Laboratoire Microorganismes : Génome et Environnement- UMR 6023, Clermont-Ferrand, France ; Insitut de Chimie de Clermont-Ferrand – UMR 6296, Clermont-Ferrand, France
    • About me and my research: The aim of our study was to elucidate the metabolic processes involved in sulfonamide biodegradation by using the sulfonamide-mineralizing bacterium Microbacterium C448, present in the environment, and the sulfamethazine (SMZ) antibiotic as models. Our starting hypothesis is the following one: at low SMZ concentrations, C448 could mineralize it without activating its resistance pathway, while the bacterium would need to resist to be able to degrade it at high concentrations. Our first results of the proteom analysis confirmed the use of the SMZ degradation pathway in vivo conditions, and a dependance of the proteins involved in degradation to the SMZ concentration. However, while the resistance pathway was used at a low SMZ concentration, Microbacterium sp. C448 did not use this pathway at high SMZ concentration, suggesting that another restistance pathway was involved or that SMZ was toxic only at a low concentration.

3rd price ex-aquo (450€) : Ana Miguel Rios for her presentation on “Organic micropollutant degradation in a membrane bioreactor inoculated with activated sludge”

Ana B Rios-Miguel

  • Status : 3rd year PhD student
  • Lab: Department of Microbiology, Radboud University, Nijmegen, The Netherlands
  • About me and my research: I am a motivated PhD student interested in microbial metabolism. My current research focuses on improving biodegradation of pharmaceuticals in wastewater treatment plants. More specifically, I am trying to decipher the metabolic mechanisms underlying their removal in order to correctly predict it and enhance it.

3rd price ex-aquo (450€) : Loren Billet for her presentation on “Antibiotics favor the establishment of antibiotrophic bacteria in agricultural soil microbial communities, but are not always sufficient to enhance antibiotic-degradation: manure spreading can help.

Loren Billet

  • Status: 3rd year PhD student
  • Labs:INRAE, UMR Agroecology, Dijon, FRANCE ; INRAE, UR Riverly, Villeurbanne, FRANCE
  • About me and my research: After a microbiology master degree focusing on ecotoxicological issues and internships on pesticide-degrading bacteria, I became interested in antibiotics as emerging pollutants and the associated bacterial functions. My work aims at better understanding the antibiotrophic function (use of antibiotics as substrates), and in particular its impact on the spread of antibiotic-resistant bacteria in agro-ecological systems.
Flash presentation:

1st price (800€) : Lauris Evariste for his poster on “Gut microbiota and host-related responses of Xenopus laevis tadpoles exposed to nanoparticles


  • Status : post doc
  • Lab: UMR 5245 ECOLAB – Laboratoire Ecologie Fonctionnelle et Environnement, Toulouse, France.

(Current lab: UMR 1331 Toxalim, Toulouse, France)

  • About me and my research : The different research works that I managed were in the field of the ecotoxicology. Thereby, I studied the effects induced by different contaminants on various organisms from multiple trophic levels. My research works evolved toward a more integrative ecotoxicology, considering interactions between organisms in response to environmental stress, especialy in the case of the links between the disturbances induced in the gut bacterial communities and the consequences on host physiology.

2nd price (500€) : Mégane Noyer for her poster on “Archaea and Bacteria evolve differently in response to a Mediterranean extreme storm event

Megane Noyer

  • Status: 3rd year PhD student (thesis defense on December 17th, 2020).
  • Lab: UMR 5110 CEFREM – Centre de Formation et de Recherche sur les Environnements Méditerranéens, Perpignan, France

About me and my research: My university course was based on ecotoxicology, and then I specialised in microbial ecotoxicology via my internships and my thesis. My research aimed to determine the impact of pollutant mixtures on the evolution of the fluvial microbiome during extreme rainfall events via multivariate statistical analyses coupling high throughput sequencing data to a wide range of environmental parameters. Now, I am looking for a post-doc position.

3rd price ex-aquo (250€) : Camila Diaz-Vanegas for her poster on “Field testing of two filling materials for the bioremediation of arsenic-rich Acid Mine Drainage


  • Status : 2nd year PhD student
  • Lab : HydroSciences Montpellier, Montpellier, France
  • About me and my research: I am Colombian PhD student in Water Science at Montpellier University, my research is focused in the optimization of biological processes for the treatment of arsenic-rich acid mine drainage. With master degree in Sustainable Management of Pollution at ISA, Lille. I am passionate in sustainable remediation and have experience in characterization of contaminated sites and assessment of bioremediation processes. I am resourceful and able to work at field and laboratory conditions.

3rd price ex-aquo (250€) : Tamara van Bergen for her poster on “Biodegradation rates of pharmaceuticals in activated sludge are dependent on concentration”

tamara-fieldwork 2

  • Status: 3rd year PhD student
  • Lab: Environmental Science, Radboud University, The Netherlands
  • About me and my research: I am an environmental scientist with a broad interest in global biogeochemical cycles, mitigation of anthropogenic stressors on ecosystems, wastewater purification and ecological engineering. I am fascinated by the interaction between biotic and abiotic components of (eco)systems. My PhD project aims to assess biodegradation of chemicals of emerging concern in wastewater treatment plants by relating physico-chemical properties, genetic/enzymatic characteristics of microbes and physical conditions in treatment plants.

International Conference EcotoxicoMic 2017

The First International Conference on Microbial Ecotoxicology was held in Lyon (France) on November 21-24, 2017. Organized by the EcotoxicoMic Network and the Rovaltain Foundation, the conference gathered for the first time more than 160 microbial ecotoxicologists representing 23 countries from around the world and belonging for both the private and academics sectors.

Thanks to the support of our many partners, the quality of the presentations and the presence of world-renowned speakers, this  event  was  fruitful, leading to numerous exciting communications, discussions and prospects of collaboration . We hope that it will  start  a  long  series of passionate conferences dedicated to Microbial Ecotoxicology!
