The rhodanese enzyme of Ferrobacillus ferrooxidans (Thiobacillus ferrooxidans)
Canadian Journal of Biochemistry, 1969Extract of sulfur-grown Ferrobacillus ferrooxidans contains the thiosulfate-splitting enzyme rhodanese. Rhodanese was purified about 40-fold and was shown to have a wide pH optimum (pH 7.5–9.0). The Km for thiosulfate and cyanide was 5.8 × 10−4 M and 1.1 × 10−2 M, respectively.

Acidithiobacillus ferrooxidans
Trends in Microbiology, 2019Acidithiobacillus ferrooxidans is by far the most widely studied of all extremely acidophilic prokaryotes. While it is found in many types of natural low-pH environments in a variety of geoclimatic contexts, it has been more widely cited in anthropogenic (mostly mine-impacted) environments.

The Sulfite Oxidase of Thiobacillus ferrooxidans (Ferrobacillus ferrooxidans)
Canadian Journal of Biochemistry, 1971The sulfite oxidase (sulfite: cytochrome c oxidoreductase) from sulfur-grown Thiobacillus ferrooxidans was isolated and partially purified, and its properties were studied. The enzyme was purified 7.3-fold and was 75–85% of the protein present. Sulfite oxidase required SO32− for activity, and could use horse heart cytochrome c and ferricyanide as ...

Isolation of the Thiobacillus ferrooxidans ntrBC genes using a T. ferrooxidans nifH-lacZ fusion [PDF]
Microbiology (United Kingdom), 1994 An agar plating technique was developed in which the activation of expression of a Thiobacillus ferrooxidans nifH-lacZ gene fusion was used to isolate the ntrBC genes from a T. ferrooxidans gene library. An Escherichia coli ntrC mutant containing the nifH-lacZ fusion was transformed and plated on a low-nitrogen medium so that on flooding with ONPG, the

Acidithiobacillus ferrooxidans and its potential application
Extremophiles, 2018The widely distributed Acidithiobacillus ferrooxidans (A. ferrooxidans) lives in extremely acidic conditions by fixing CO2 and nitrogen, and by obtaining energy from Fe2+ oxidation with either downhill or uphill electron transfer pathway and from reduced sulfur oxidation. A.

Sulfur-oxidizing enzyme of Ferrobacillus ferrooxidans (Thiobacillus ferrooxidans)
Canadian Journal of Biochemistry, 1968The sulfur-oxidizing enzyme was purified about 15-fold from sulfur-grown Ferrobacillus ferrooxidans. The enzyme has a pH optimum of 7.8 and requires both elemental sulfur and reduced glutathione (GSH); however, a glutathione–polysulfide complex could also serve as substrate. The Km for GSH was determined to be 2 × 10−3 M.
