Scientists Discover Bacteria that Poops Pure Gold

This popped up on a Geology page I frequent ; not sure if it's current affair. They are presenting it as such , non the less it's very interesting.


Bacteria eats poison, poops out gold

The gold you see in the photo above was not found in a river or a mine. It was produced by a bacteria that, according to researchers at Michigan State University, can survive in extreme toxic environments and create 24-karat gold nuggets. Pure gold.

This scenario may sound like a biochemist’s version of a fairy tale, but it’s real and scientists at McMaster University have just described how the process works in an article published online in the journal Nature Chemical Biology.

The bacteria is called Delftia acidovorans, and it turns out that its King Midas-like conversion is part of a self-defense mechanism. Gold ions dissolved in water are toxic, so when the bacteria senses them it releases a protein called delftibactin A. The protein acts as a shield for the bacteria and changes the poisonous ions into harmless particles that accumulate outside the cells.

Although the amount of gold that Delftia acidovorans release is tiny (the particles are 25-50 nanometers across) it’s possible that the bacteria or the protein could someday be used to dissolve gold from water or to help people identify streams and rivers carrying the mineral.

Maybe this critter can save us all from the global economic crisis?

Of course not—but at least it can make Kazem Kashefi—assistant professor of microbiology and molecular genetics—and Adam Brown—associate professor of electronic art and intermedia—a bit rich, if only for the show they have put together.

Kashefi and Brown are the ones who have created this compact laboratory that uses the bacteria Cupriavidus metallidurans to turn gold chlroride—a toxic chemical liquid you can find in nature—into 99.9% pure gold.

Accoding to Kashefi, they are doing "microbial alchemy" by "something that has no value into a solid [in fact, it the toxic material they use does cost money. Less than gold, but still plenty], precious metal that's valuable."

The bacteria is incredibly resistant to this toxic element. In fact, it's 25 times stronger than previously thought. The researchers' compact factory—which they named The Great Work of the Metal Lover—holds the bacteria as they feed it the gold chloride. In about a week, the bacteria does its job, processing all that junk into the precious metal—a process they believe happens regularly in nature.

So yes, basically, Cupriavidus metallidurans can eat toxins and poop out gold nuggets.

It seems that medieval alchemists were looking for the Philosopher's Stone—the magic element that could turn lead to gold—in the wrong place. It's not a mineral. It's a bug.

I can shit bricks so if I eat some of that bacteria do you think my toilet will be Fort Knox #2!

Imagine finding gold on Uranus.
