Sulfide oxidation by spheroplasts of Thiobacillus ferrooxidans [PDF]
Applied and Environmental Microbiology, 1978 Thiobacillus ferrooxidans is an acidophilic organism important to metal leaching of low-grade ores. The aforementioned importance is related to the ability of the bacterium to oxidize reduced iron and sulfur, principally found in nature as pyrite (FeS2).

The role of iron oxidizing bacteria to the quality of leachate on acid sulphate soil
Ilmu Pertanian (Agricultural Science), 2020 The problem encountered in acid sulphate soil is the presence of pyrite (FeS2) which causes soil to have highly acid reaction when the pyrite is oxidized.

Sulfur-binding protein of flagella of Thiobacillus ferrooxidans [PDF]
Journal of Bacteriology, 1996 The sulfur-binding protein of Thiobacillus ferrooxidans ATCC 23270 was investigated. The protein composition of the bacterium's cell surface changed according to the culture substrate. Sulfur-grown cells showed greater adhesion to sulfur than iron-grown cells. The sulfur-grown cells synthesized a 40-kDa surface protein which was not synthesized by iron-

Polythionate degradation by tetrathionate hydrolase of Thiobacillus ferrooxidans [PDF]
Microbiology, 1997 Cell-free extracts of Thiobacillus ferrooxidans grown with thiosulfate as energy source and prepared at high ammonium sulfate concentrations and at low pH are capable of polythionate hydrolysis. The enzyme responsible for the hydrolysis of tetrathionate (S4O2- 6) and pentathionate (S4O2- 6) was purified to ...
