Microbial metal

It is crucial to understand the transport and deposition of technologically important metals such as platinum. Now, a team at the University of Adelaide, Australia, have revealed the role of bacteria in the formation and movement of platinum and related metals in surface environments. Project leader Frank Reith explains that, “These platinum group elements are strategically important metals, but finding new deposits is becoming increasingly difficult due to our limited understanding of the processes that affect the way they are cycled through surface environments." The new insight into the role of bacteria could improve understanding of the bio-geochemical processes taking place in deposits and boost our ability to find and extract such metals.
