The bacterium does not make the gold. It separates it from the gold chloride molecule.
The only things in the universe that create gold atoms are supernovae. On earth, nuclear transmutation is possible in principle (via particle accelerators, tokamaks, etc.) but I don't think anyone has set up a process to make gold successfully that way.

No. It is research, and a terrible headline.

Gold isn't the end goal here. Bacteria that survive in heavy metal solutions are pretty rare. Bacteria that do something useful with those heavy metal solutions are even rarer. The end goal is probably to find and/or create bacteria that can treat large quantities of contaminated water. Water contaminated with other heavy metals like lead, arsenic, etc. Unleashing a heavy-metal leeching bacteria has got to be cheaper than treating a huge quantity of contaminated water. It might take a lot longer, and not be as efficient, but you better believe there is a use and a market for bacteria that can do that. This is just a step along the way.

Where is gold-chloride found in nature? A quick google search and all I could find were descriptions describing gold-chloride as something created in a lab.
I think this was done as a what if experiment and has no practical use. The point though is if you can create a bacteria that will concentrate gold in either industrial or natural compounds if could be very useful. Right now mercury is the main element used in processing gold ore. Japan started extracting gold from sewage. I thought it was a silly idea until I heard how much they extracted. I'm not sure what the source of the gold is, old fillings wearing or naturally occurring but they did get a respectable amount from the sewage. Most of the world's available gold is actually suspended in seawater. The downside is it costs more to extract it than the gold is worth. Say you develop a bacteria that seeks out and absorbs gold then sinks to the bottom of the tank. You could over time end up with a coating of gold on the tank bottom. A similar process has been developed for removing radioactive elements from drinking water.

It's not alchemy. That would be creating gold from other elements. This is simple refining.

Gold from gold chloride is truly not interesting. Gold from seawater -- that would be interesting. Gold from seawater at macroscopic rates with no external energy input in unattended apparatus, that would be very interesting. Sadly, this is not that.

"Create natural gold"? by Anonymous Coward · 2012-10-03 02:14 · Score: 0

The phrase "to create natural gold" suggests poor scientific knowledge. No bacteria can "create" gold, be it "natural" or... not.

Reduction [Re:throw out the dictionary, you ar...] by Geoffrey.landis · 2012-10-03 02:19 · Score: 1

This bacteria refines gold compounds.

More accurately, it reduces gold. That is, it makes gold metal from gold ions.

The word is "reducing". by Sans_A_Cause · 2012-10-03 03:58 · Score: 1

The bacteria are reducing gold ions to elemental gold. They are not "creating" or "extracting" gold. This simple oxidation/reduction chemistry.

Clockwork Angels by ekimminau · 2012-10-03 05:17 · Score: 1

The Percussionist Neil Peart http://en.wikipedia.org/wiki/Neil_Peart of the band Rush http://en.wikipedia.org/wiki/Rush_(band) released a book "Clockwork Angels" http://www.goodreads.com/book/show/13592828-clockwork-angels

co-authored with Kevin J. Anderson http://www.goodreads.com/author/show/4845.Kevin_J_Anderson which has a number of Antagonists, among which is "the clockmaker" who takes over society through the creation and a massive influx of "artificially created" gold. The second primary antagonist has created "artificially created" diamonds. Quite timely I believe. Well played Mr. Peart! Well played!
