Fungus recovers precious metal from waste water

A fungus better known for eating dead wood can also recover the world’s most precious metal from waste water and even add value to it. Palladium overtook gold and platinum as the world’s most expensive metal earlier this year as demand from auto-makers outstripped supply. The element is used in vehicle exhaust systems to curb harmful emissions but manufacturers are currently only able to recover and recycle about a third. Now, chemists at Loughborough University in England say a species of fungus can simplify the recovery process; creating palladium nano-particles that can be re-used in other industries. In laboratory-based experiments, the researchers used white rot fungus, phanerochaete chrysosporium, to absorb palladium from industrial effluent and found it also reduced palladium ions to nanoparticles – a valuable commodity in their own right.
