Bacterium helps formation of gold
Date: 13.10.2009
Australian scientists have found that the bacterium *Cupriavidus metallidurans* catalyses the **biomineralisation** of **gold** by transforming toxic gold compounds to their metallic form using active cellular mechanism.
Researchers reported the presence of bacteria on **gold surfaces** but have never clearly elucidated their role. Now, an international team of scientists has found that there may be a **biological reason** for the presence of these bacteria on gold grain surfaces.
