Mining copper with microbes

Copper is an important bulk metal for the German industry: it is mainly used in the cable and electrical industry, but also in the construction and automotive sectors, and in mechanical engineering. Until now most of it had to be imported either in the form of metal concentrates or crude ore. The world market leader Chile has been an important copper partner for Germany.

Novel biosurfactants to hit the market

They are found in cosmetics, pharmaceuticals, cleaning agents, on seeds and even in fire extinguishers: surfactants. These substances reduce the surface tension of a liquid or the interfacial tension between two liquid phases. Surfactants can be used to mix generally immiscible liquids together or separate them from each other in a controlled manner.
In mid-December, Biotensidon GmbH, a Karlsruhe-based subsidiary of the Swiss firm Biotensidon International AG, announced a breakthrough in the mass production of rhamnolipid surfactants.

The foundation for next-generation-but-one vehicle technology has just been laid in the car manufacturing city of Wolfsburg. In the presence of Federal Minister of Research Johanna Wanka, the LeichtbauCampus Open Hybrid Lab Factory was inaugurated at a location not far from the headquarters of VW.
