Bundesanstalt für Geowissenschaften und Rohstoffe

The Federal Institute for Geosciences and Natural Resources (BGR) with about 700 employees is the central geoscientific authority providing advice to the German Federal Government in all geo-relevant questions. It is subordinate to the Federal Ministry for Economic Affairs and Energy (BMWi). The BGR geomicrobiology unit belongs to the department for raw materials and has specific expertise in the field of metal extraction using microorganisms (bioleaching/ biomining). Since 1973 several projects in this field have been carried out and the results have regularly been published in international recognized journals (> 100 papers). Additional geomicrobiological R&D projects are currently carried out concerning carbon capture and storage (CCS), microbial degradation of hydrocarbons, and the deep biosphere.

The work of the geomicrobiologists includes the analysis of microbial communities in environmental samples using molecular methods as well as the isolation and characterisation of microorganisms and the maintenance of the collection of bacteria and fungi (> 1000 strains). Their tasks also include the identification of metabolic products of microorganisms. At the same time, the scientists offer interdisciplinary support to other working groups within the BGR including the Deutsche Rohstoffagentur (DERA). They also cooperate with foreign partners in research projects, scientific-technical cooperation (WTZ), and in projects of technical cooperation (TZ).

Current third party funded projects in BGR geomicrobiology related to biomining:

EcoMetals is a transnational research project aiming at the development of innovative biohydrometallurgical processes for the extraction of copper and other (associated) metals from coppershale.. The project receives funding from the French ANR (L’Agence nationale de la recherche) and the German Ministry of Education and Research BMBF (Bundesministerium für Bildung und Forschung) under the reference number 033RF001.

In total, 17 partners from science and industry collaborate in this project. Start of the project was in February 2014 and it will run until June 2017.
