Welcome to the 6th Symposium on remediation in Jena
"Jenaer Sanierungskolloquium"
focusing on
"Microbe-mineral interfaces at heavy metal polluted sites"

The 6th Symposium on remediation is dealing with microorganisms affecting the minerals at heavy metal polluted sites, at the same time allowing application for bioremediation. This process includes plant-microbe and complex microbe-substrate interactions. They are reflected by biological, geological, physical and chemical properties, which all have to be investigated in detail to allow the prediction of sustainable associations with the prospect of application to in-situ remediation.

The symposium includes 5 sessions with 24 talks and poster presentations, and participants from 10 countries are here to exchange their knowledge. Session 1 starts with bacterial resistance on heavy metals and associated effects on their metabolism. Session 2 focusses on symbiotic interactions of soil fungi with plants. Session 3 deals with the influences on reactive transport, especially of the microbial impact, and session 4 shows different applications in bioremediation. Finally, analytical tools to investigate bio-geo-interactions will be introduced in session 5.

Bio-geo-interactions are in the focus of the research of the Friedrich Schiller University of Jena. PhD projects of the graduate school “Alteration and element mobility at the microbe-mineral interface” supported by the German Research Foundation (DFG), as well as research projects supported by the German Ministry of Education and Technology are presented in this symposium. All projects here are of the Jena School for Microbial Communication. This research focus of the Friedrich Schiller University is also reflected by the newly established BSc/MSc program Biogeosciences and the MSc Microbiology.
