Thats pretty interesting, I wonder if they will ever be able to grow this bacteria in the lab and if so create their own gold much like how some people grow crystals with a seed and some type of chemical solution..
And in going with that idea what effect would it have on the gold market (value etc)... if its anything like fake diamonds being impossible to make without the right tools also maybe it takes hundred of years for these pacteria to actually increase the size of the gold.. then I would say the price of gold is safe.. but who
knows really all guess work really.
