This is similar to certain bacteria that live in our oceans and consume oil. Most people are totally unaware that oil seeps into out oceans and seas naturally every single day. There are microbes that feed upon this oil discharge.
Several tears ago when there was an oil rig leak in the Gulf the Leftists went insane. Making all sorts of crazy doom and gloom statements. Days later, when the Leftists Media actually went to the site. There was nearly no evidence of a leak. Their doom and disaster proclamations were nonsense.
They discovered nearly no evidence of the leak. No major oil slicks. No massive fish kills or dead sea birds. The leak was Light Sweet Crude. It was consumed by these microbes that gathered by the TRILLIONS for a feast.
I read about that. :)
Coolest thing I have found was that they also can use enzymes to extract gold and silver from ore. And other metals depending on the type of enzyme.
