A gapped genome sequence of the biomining bacterium Thiobacillus ferrooxidans strain ATCC23270 was assembled from sheared DNA fragments (3.2-times coverage) into 1,912 contigs. A total of 2,712 potential genes (ORFs) were identified in 2.6 Mbp (megabase pairs) of Thiobacillus genomic sequence. Of these genes, 2,159 could be assigned functions by using the WIT-Pro/EMP genome analysis system, mos...

Investigating the effect of various sources sulfurous compounds along with inoculation Thiobacillus bacteria on corn plants under stress conditions lead and zinc metals, an experiment executed at zanjan uni researching green house. The treatments include elemental sulfur (0.75, 1.25 2 g/kg soil), (1, 3 soil) potassium sulfate (0.5, 1 1.5 soil ). results showed that traits were significant in al...

The use of Thiobacillus ferrooxidans bacteria in the process of copper and iron leaching from chalcopyrite coming from Kotlina Ktodzka was investigated. The influence of the mineral content in the leaching solution the pH value and refinement of chalcopyrite on the subsequent stages of leaching was established. The process was described by the 1st order reaction inhibited by one of the products...

bacterium Thiobacillus X. A fifth fraction (acidic fraction) contained two additional cytochrome components with x bands at 550 and 557 msi respectively in the reduced state. 2. All the cytochromes appear to be ofthe c type, are labile to heat and acid and do not combine with carbon monoxide. They are auto-oxidizable to varying degrees. 3. Cytochromes 550 (1) and 557 (1) are basic, and are adso...

Inorganic thiosulfate has been implicated as an intermediate in the assimilation of sulfate in a variety of organisms. Nutritional studies with mutants of Aspergillus have been interpreted to indicate thiosulfate as an intermediate between sulfite and cysteine (1, 2), possibly via a pathway involving cysteine-Ssulfonate as a direct precursor of cyst&e (24). Shepherd earlier had envisioned the u...

Colmer, Arthur R. (Louisiana State University, Baton Rouge). Relation of the iron oxidizer, Thiobacillus ferrooxidans, to thiosulfate. J. Bacteriol. 83:761-765. 1962.-A restudy has been made of Thiobacillus ferrooxidans secured from the acid drainage of some northern West Virginia coal mines. Cultures isolated from ferrous iron agar and then subcultured for 85 consecutive transfers in thiosulfa...
