How about indirect bioleching of uranium via iron oxidation by for ex.
Thiobacillus ferrooxidans? Isn't that bioleaching of Uranium. It was done
on a commercial scale in the 1980s in the Elliot Lake district in Ontario
at the Denison mine in particular. There was also some evidence that T.
ferrooxidans can oxidize U(IV) to U(VI) enzymatically and uses some of this
energy to assimilate CO2 although I am not sure if this hypothesis was
rejected.
