'Uranium-Eating' Bacteria To Clean-Up Radioactive Sites

Ranger Mine - a uranium mine in Kakadu National Park, Australia.

From Cosmos:

SYDNEY: Some bacteria have the capacity to stabilise uranium contaminated sites, and if they are used they could reducing the chances of these sites contaminating major waterways and ecosystems, U.S. scientists have said.

Of the millions of tonnes of bacteria living within the Earth's subsurface, some are able to transform the oxidative state of uranium, which defines how the element with interact with oxygen to form various molecules. They change it from the radioactive, toxic and water soluble uranium (VI) to the less soluble, stationary and therefore less harmful uranium (IV) as part of their normal growth.
