Investigation of Aeration Rate on Uranium Bioleaching in Internal Airlift Bioreactor [PDF]

مجله علوم و فنون هسته‌ای, 2012
Uranium is leached from the uranium ore of the second anomaly of Saghand by the Acidithiobacillus ferrooxidans bacteria in an internal airlift bio-reactor. This study has been made to find the effect of aeration rate as well as its optimal value.

Reduction of Mo6+ with elemental sulfur by Thiobacillus ferrooxidans

Journal of Bacteriology, 1988
In the presence of phosphate ions, molybdic ions (Mo6+) were reduced enzymatically with elemental sulfur by washed intact cells of Thiobacillus ferrooxidans to give molybdenum blue. The whole-cell activity that reduced Mo6+ was totally due to cellular sulfur:ferric ion oxidoreductase (SFORase) (T. Sugio, W. Mizunashi, K. Inagaki, and T.
