7th Symposium on remediation in Jena
“Jenaer Sanierungskolloquium”:

Metal Stress: biotic and abiotic factors

The 7th Symposium on remediation is dealing with metals in the environment as ecotoxicological
risk for organisms being influenced by biotic and abiotic factors. Among the biotic factors,
especially in contaminated soil, the activities of microorganisms and the chemical components
exuded by plant roots are major players. In terms of abiotic factors, the hydrogeological parameters,
mineral formation and dissolution, or physico-chemcial soil properties largely influence metal
release and reactive transport.

In this year, participants from 8 countries will present their research in 6 sessions with 40 talks and
poster presentations. Session 1 starts with metal transport in acid mine drainage waters, followed by
precipitation as (bio)mineral formation (session 2). Session 3 focuses on influence on microbial
communication, session 4 deals with plant stress response, and session 5 shows mechanisms of
interaction. Finally, protection of water paths and the food chain will be discussed in session 6.
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.
