Technically its alchemy. Michigan State University researchers have discovered a metal-tolerant bacteria, Cupriavidus metallidurans, that can survive and grow on high concentrations of gold chloride, a toxic chemical compound found in nature.
The Gold bit is important, the Chloride is highly toxic.
However it eats the chloride parts, and leaves behind the non-nutritious parts, you know, the gold. Unlike previous experiments you end up with nuggets and not nano-particles.
It looks like the bacteria is not that easy to produce in industrial quantities, yet, and where would you get the source materials. Having said that I suspect its safer than the traditional processing method of using potassium bromide (which as well as gold leaves potassium auric bromide and potassium chloride).
Also if the bacteria does escape, what can it eat? People?
Oh, turning people in to gold (and a little pulp). How very Midas. Or James Bond villain.
Superman-strength bacteria produces gold
At a time when the value of gold has reached an all-time high, MSU researchers have discovered a bacterium’s ability to withstand incredible amounts of toxicity is key to creating 24-karat gold.
