Peptidoglycan of a Chemolithotrophic Bacterium, Ferrobacillus ferrooxidans [PDF]
The rigid layer (peptidoglycan) of the wall of the chemolithotroph Ferrobacillus ferrooxidans was isolated after various chemical treatments. The removal of specific components was followed by noting in an electron microscope changes in the appearance of the cell surface.

Mixotrophic Growth of a Thiobacillus ferrooxidans Strain [PDF]
Mixotrophic growth of a Thiobacillus ferrooxidans strain is described. DNA moles percent guanine plus cytosine and homology determinations confirmed that the mixotrophically grown T. ferrooxidans cultures were not contaminated with heterotrophic Acidiphilium strains.

Cloning of a Thiobacillus ferrooxidans plasmid in Escherichia coli [PDF]
Three separate plasmids of 6, 7, 16, and greater than 23 kilobases were purified from a single clone of Thiobacillus ferrooxidans ATCC 33020 grown in the presence of uranium. The 6.7-kilobase plasmid (pTf1) was cloned separately into the HindIII or BamHI site of Escherichia coli plasmid pBR322.

Corrosion Behavior of Cast Iron in the Presence of Acidithiobacillus Ferrooxidans
Ferrooxidans bacteria occur widely in acid mine drainage water. This work examined the corrosion behavior of cast iron in the presence of the acidophilic iron-oxidizing bacterium Acidithiobacillus ferrooxidans (T.f).

Pyrite oxidation under initially neutral pH conditions and in the presence of Acidithiobacillus ferrooxidans and micromolar hydrogen peroxide [PDF]
Hydrogen peroxide (H2O2) at a micromolar level played a role in the microbial surface oxidation of pyrite crystals under initially neutral pH. When the mineral-bacteria system was cyclically exposed to 50 μM H2O2, the colonization of Acidithiobacillus ...
