In situ spectroscopy on intact Leptospirillum ferrooxidans reveals that reduced cytochrome 579 is an obligatory intermediate in the aerobic iron respiratory chain [PDF]

open access: yes, 2012
Electron transfer reactions among colored biomolecules in intact bacterial cells were monitored using an integrating cavity absorption meter that permitted the acquisition of accurate absorbance data in suspensions of cells that scatter light.

Continuous leaching of uranium by Thiobacillus ferrooxidans.

open access: yesAgricultural and Biological Chemistry, 1976
The continuous culture of Thiobacillus ferrooxidans and the continuous leaching of uranium by it were investigated by means of an apparatus for single stage continuous culture. For the specific growth rate on ferrous sulfate medium, the optimum pH, temperature and aeration were between 2.3 and 2.7, between 29 and 34°C and above 5.0 × 10−7 gmole O2/ml ...

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

open access: yesمجله 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.
