Scientists Produce Gold Using Bacteria
Michigan State University researchers have found a way to use the metal-tolerant bacteria 'Cupriavidus metallidurans' to turn liquid gold into solid, 24-karat gold.
Michigan State University researchers have found a way to produce 24-karat gold from liquid gold using bacteria. Assistant professor of microbiology and molecular genetics, Kazem Kashefi, and associate professor of electronic art and intermedia, Adam Brown, found the metal-tolerant bacteria Cupriavidus metallidurans can grow onto liquid gold a toxic chemical compound found in nature. The bacteria transforms the toxins and produces a gold nugget.
Their art installation ‘The Great Work of the Metal Lover' uses a combination of biotechnology, art, and alchemy. It contains a portable laboratory made of 24-karat gold-plated hardware and a glass bioreactor. A series of art prints have also been made that contain some of the gold produced in the bioreactor.
