These bacteria literally poop gold. Researchers are studying a metal-eating bacterium name Cupriavidus Metallidurans that can ingest toxic metal compounds, survive the negative effects and produce small nuggets of gold. The key to the bacteria’s’ mechanism is its home.

Are there bacteria that eat gold?

An international team of researchers has figured out how one metal-gobbling bacterium, Cupriavidus metallidurans, manages to ingest toxic metallic compounds and still thrive, producing tiny gold nuggets as a side-effect.

Where can I buy Cupriavidus metallidurans?

Cupriavidus metallidurans BS1 was isolated from a gold copper mine in China and was found to have 99.9–100% 16S rRNA gene identity to available genomes in the National Center for Biotechnology Information (NCBI) database of C.

Can bacteria grow on gold?

Reith found some of the first convincing evidence that bacteria thrive on gold particles about ten years ago. At multiple sites, thousands of kilometers apart, he and his team found the bacterium Cupriavidus metallidurans living in biofilms on gold nuggets.

What can the Ralstonia Metallidurans bacteria do?

According to discoverer Frank Reith, Ralstonia metallidurans “is able to survive in concentrations of gold that would kill most other micro-organisms” (1). Not only can these microbes withstand toxic concentrations of metals, they are found to be able to precipitate gold.
