It's not exactly "eliminating" the pollution, but the bacteria are certainly making it more manageable by converting it from a dissolved to a solid form. There isn't any biological pathway, that I know of, anyway, that can eliminate radioactive isotopes.
Apparently, these little buggers enable the metabolism of soluble radioactive contaminants into insoluble harmless forms. That really is an incredible capability that would help with the concern about the use of nuclear power in the US as one of the ways to get us off the teat of foreign oil.
But...don't worry...the anti-nuke crowd will come up with something of concern and block efforts to use the technology and in the end, this will never be adopted.
It's amazing to think that we are so worried about what might happen if Uranium gets loose, bacteria truly is the greatest living creature on this earth.
Step 1: Build nuclear power plant in the middle of nowhere Nevada, one mile underground.
Step 2: Use bacteria to take care of waste
Step 3: Wait, that would mean cheap energy for our peons... CANCEL STEP ONE! ABORT! ABORT!!!!!
Lets throw some bacteria eating uranium in the doomed Chernobyl reactor, and then it can be buried in giant steel coffin.
These neocons want to fool you into thinking using Depleted Uranium isn't going to be the disaster of the century!
Do you have any idea how many people have been maimed or killed by Depleted Uranium?
Do you think you should find out?
Uranium is an element, "Elements cannot be reduced to simpler substances by normal chemical means." http://www.answers.com/element&r=67
So unless this bacteria can smash atoms it can't break down Uranium.
Its a fundamental principle of chemistry. Think before you bury
I don't know if I trust this stuff enough to be putting it in the water but using it to combat radioactive waste is pretty cool. I just think we need to keep it away from the water supply until we know everything that there is about it and then some.

It's kinda cool to think that an organism could utilize the energy from radioactive materials. It has implications for how long the organism could benefit from a few atoms of this . . . conceivably for years, centuries. What a great science fiction concept. Combine radio active materials into human cells and you could live without oxygen for long periods of time, or with out energy source foods.
2 things
1) Will those bacteria become radio active after they eat :)
2) Even Cow Dung (yes cow excetea) blocks Radio Activiy , (Hindu mythology facts which is true)
It would be more accurate to say that these bacteria "breathe" uranium by using it as a terminal electron receptor.I think. It's also possible they're reducing sulfur compounds (which is very similar to oxygen) and making the uranium precipitate as uranium sulfide.
Organisms like this usually don't grow very well because there's nothing quite like oxidizing organic compounds all the way down with oxygen to produce a lot of electrons for oxidative phosphorylation.
