Lipopolysaccharides of iron-oxidizing Leptospirillum ferrooxidans and Thiobacillus ferrooxidans.
Lipopolysaccharides were isolated from one strain of Leptospirillum ferrooxidans and three strains of Thiobacillus ferrooxidans. All strains contained 2-keto-3-deoxyoctonate (KDO), heptose(s) and glucosamine besides neutral sugars, but were devoid of phosphorus.

Production and Regeneration of Thiobacillus ferrooxidans Spheroplasts [PDF]
We investigated the production and regeneration of Thiobacillus ferrooxidans spheroplasts. Regeneration frequencies of up to 90% reversion were obtained. Attempts to transform T. ferrooxidans spheroplasts with a recombinant T. ferrooxidans plasmid were unsuccessful.

Toxins VapC and PasB from Prokaryotic TA Modules Remain Active in Mammalian Cancer Cells
Among the great number of addictive modules which have been discovered, only a few have been characterized. However, research concerning the adoption of toxins from these systems shows their great potential as a tool for molecular biology and medicine.

Continuous leaching of uranium by Thiobacillus ferrooxidans.
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 ...

Reduction of Mo6+ with elemental sulfur by Thiobacillus ferrooxidans
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.
