Biomolecules, bacteria and other microorganisms considerably influence geochemical processes such as the formation or weathering of rocks. They bind to mineral surfaces or convert minerals through metabolic processes. Furthermore, many biological components interact with dissolved metals in their environment, bind them or transform them. Together with modern biotechnologies, these mechanisms can be used to develop energy-efficient, environmentally-friendly and economic technologies.
At the Helmholtz Institute Freiberg for Resource Technology, the Biotechnology Department predominantly conducts research for the development of biotechnological extracting and recycling procedures, also known as Biomining. The group aims at high-tech metals from primary and secondary raw materials. This includes the biological extraction of metals from raw materials (bioleaching), the selective binding and recovery of metal ions from aqueous solutions (biosorption) and the selective particle separation with biological agents (bioflotation).
For this purpose, the biologists work closely with the other departments at the institute. Apart from developing new technologies, the focus is on fundamental microbiological research such as understanding the interactions of microorganisms or biomolecules with the metals and minerals in their environment.
