Superman-strength bacteria produce gold

EAST LANSING, Mich. — At a time when the value of gold has reached an all-time high, Michigan State University researchers have discovered a bacterium’s ability to withstand incredible amounts of toxicity is key to creating 24-karat gold.

“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.

He and Adam Brown, associate professor of electronic art and intermedia, found the metal-tolerant bacteria Cupriavidus metallidurans can grow on massive concentrations of gold chloride – or liquid gold, a toxic chemical compound found in nature.

In fact, the bacteria are at least 25 times stronger than previously reported among scientists, the researchers determined in their art installation, “The Great Work of the Metal Lover,” which uses a combination of biotechnology, art and alchemy to turn liquid gold into 24-karat gold. The artwork contains a portable laboratory made of 24-karat gold-plated hardware, a glass bioreactor and the bacteria, a combination that produces gold in front of an audience.

Brown and Kashefi fed the bacteria unprecedented amounts of gold chloride, mimicking the process they believe happens in nature. In about a week, the bacteria transformed the toxins and produced a gold nugget.

    Wasn't there a story here about a nobel prize winner who dissolved his medal so that he could sneak it out of Nazi Germany? Then reconstituted it so he could have it restruck, or something to that effect.

    Since you must use gold to produce gold chloride, my question is: is it cost effective? If so, by what % do you increase your final product from the amount required in the gold chloride solution.

    "Gold(III) chloride, traditionally called auric chloride, is a chemical compound of gold and chlorine."

    When Nazi Germany invaded Denmark in World War II, the Hungarian chemist George de Hevesy dissolved the gold Nobel Prizes of Max von Laue and James Franck in aqua regia to prevent the Nazis from stealing them. He placed the resulting solution on a shelf in his laboratory at the Niels Bohr Institute. After the war, he returned to find the solution undisturbed and precipitated the gold out of the acid. The Nobel Society then recast the Nobel Prizes using the original gold.

    Only if the feed is made of gold.

    interesting story.

    I wish the clueless author would have stayed away from the ridiculous alchemy word.

    it is a chemical transformation and it does not trasmutate the nucleus and electrons of one atom into another.
