Bacteria that produce pure gold revealed

Scientists have discovered a bacterium that eats toxic material and, well, poops pure gold. This microbial magician, named Cupriavidus metallidurans, when placed in a minilab full of gold chloride, a nasty toxin, gobbled up the poison and, in about a week, processed it out as 24-karat nuggets of the precious yellow metal.

The bacterium was found to be 25 times more resistant to the gold-based toxic chemical than believed and most likely does its amazing alchemy regularly in nature.

“Microbial alchemy is what we’re doing — transforming gold from something that has no value into a solid, precious metal that’s valuable,” said Kazem Kashefi, assistant professor of microbiology and molecular genetics.
