8th Symposium on remediation in Jena
“Jenaer Sanierungskolloquium”:

Geo-bio-processes at geochemical barriers

The 8th symposium on remediation focuses on geo-bio-processes in formation of geochemical barriers, especially on heavy metals and radionuclides resulting from acid mine drainage and the physico-/chemical parameters characterizing the substrates as the main factor for formation of the barriers. Additionally, microbial processes influencing dissolution and precipitation at geochemical barriers are covered. Thus, the remediation symposium focuses on both microbial impact and the physico-/chemical processes that considerably modify the barriers and equally also near-surface mineral deposits.


The former uranium mining district of Eastern Thuringia represents one of the most cost intensive remediation projects world-wide, and at the same time also provides a perfect research area for basic and applied sciences in geo-bio-interactions. The established geo-bio-interaction methods may provide a cost reduction involving new technologies in soil-improvement and bioremediation for defined targets. Thus, this symposium aims at a knowledge improvement with regard to biologically influenced geological, chemical and physical processes at geochemical barriers.

Geo-bio-interaction has become an interdisciplinary focus across departments at the University of Jena. The Ph.D. program “Alteration and element mobilization at microbe-mineral interfaces” funded by the German Research Foundation, as well as associated research projects, e.g. supported by the German Ministry of Education and Technology, contribute efficiently to this development. Having been in place for 5 years now the Biogeosciences B.Sc. and M.Sc. programs provide the basis for such research.

In session 1, case studies for geochemical barriers are presented. In session 2, geomicrobiological processes are viewed in the light of their influence on geochemical barriers. Session 3 deals with specific applications improving soil formation and plant growth. Session 4 is dedicated to the contributions on the fractionation processes, e.g. rare earth elements and stabile isotopes. Session 5 deals with specific mineralogical formations, session 6 on comparable processes in relation to the formation of near-surface mineral deposits.

We welcome you warmly to the 8th remediation symposium in Jena and invite you to participate.
