Bioleaching of low grade uranium ore containing pyrite using A. ferrooxidans and A. thiooxidans [PDF]
, 2012 A process of uranium extraction from ore containing 3.1 % pyrite by bacterial leaching was investigated in shaken flasks during 90 days. The highest uranium recovery amounting to 85.1 % was obtained using binary mixture of Acidithiobacillus ferrooxidans ...

Chloride Ingress in Cement Mortars Exposed to Acidithiobacillus thiooxidans Bacteria
Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020 Concrete structures placed in aggressive aqueous environments are vulnerable to degradation. Majority of studies have linked structural failures to the ingress of deleterious ions into the cement matrix. Some microbial activities may accelerate the penetration of harmful materials into the cement matrix and hence cause pronounced deterioration.

Fatty Acids of Thiobacillus thiooxidans [PDF]
Journal of Bacteriology, 1971 Fatty acid spectra were made on Thiobacillus thiooxidans cultures both in the presence and absence of organic compounds. Small additions of glucose or acetate had no significant effect either on growth or fatty acid content.
