9th Symposium on remediation in Jena "Jenaer Sanierungskolloquium":

Microbial impact on element mobility

4th - 5th October, 2010
Friedrich Schiller University
Wöllnitzer Str. 7
07749 Jena

The 9th Symposium on remediation is dealing with the impact of microorganisms on the biogeochemical changes in the environment. These will include specifically the responses of both bacteria and fungi tobioavailable fractions of metals in soil and the water phase. The molecular mechanisms induced in cells dealing with heavy metal stress encompass intracellular and extracellular proteins induced under these conditions. As a result of altered gene expression, the bioavailability of metals is changed and thus a regulatory loop is formed in the environment governed by microbial physiology. The interaction with the environment provides new conditions which influence abiotic reactions in reactive transfer and mobility of metals, both in interaction with soil or mineral interfaces, and with ground and surface waters.

International participants will present their research in 6 sessions with 30 talks and additional poster presentations. Session 1 starts with heavy metals and radionuclides in the environment, with Sessions 2 and 3 are devoted to bacterial and fungal resistance mechanisms, respectively. On Tuesday morning, the meeting will continue with Session 4 on microbial communities, to be followed by Session 5 on Plant interactions and a concluding session integrating latest results on the soil-water system, nutrition and physiology. One invited speaker will open each session, to be followed by presentations of young researchers to be selected from the application.

PhD projects of the graduate school "Alteration and element mobility at the microbe-mineral interface" supported by the German Research Foundation (DFG), of the Excellence Graduate School "Jena School for Microbial Communi­cation", as well as research projects supported by the German Ministry of Education and Technology are presented in this symposium. The research focus of Bio-Geo-Interactions at the Friedrich Schiller University is also reflected by MSc programs in Biogeosciences and Microbiology.

We welcome you warmly to the 9th remediation symposium in Jena and invite you to participate.
