Microbial processing of apatite rich low grade Indian uranium ore in bioreactor

- Bioreactor leaching of uranium by Acidithiobacillus ferrooxidans and Leptosprillium ferrooxidans improved the kinetics.
- Uranium leaching was 57% and 63% in 5 days with pure culture of A. ferrooxidans and L. ferrooxidans.
- Biogenic Fe(III) with L. ferrooxidans and A. ferrooxidans leached 90% and 87% uranium in 10 h.
- Fe(III) biogenically enhances the kinematics of uranium dissolution in bioreactors.
