Combined degradation of covellite by Thiobacillus thiooxidans and Thiobacillus ferrooxidans

Biotechnology Letters, 1996
In the presence of iron, which is always associated with natural sulphide ores, the percentages of copper dissolution in the bioleaching of covellite were 34 and 45 % when Thiobacillus thiooxidans and Thiobacillus ferrooxidans were used together and when an indirect bioleaching with attached bacteria was performed respectively.

Thiobacillus acidophilus: a study of its presence in Thiobacillus ferrooxidans cultures

Canadian Journal of Microbiology, 1980
A study had been undertaken to account for the presence of Thiobacillus acidophilus in iron-grown cultures of Thiobacillus ferrooxidans. Attempts to adapt T. acidophilus to ferrous iron were not successful but the facultative autotroph grew to a limited extent in the spent medium of T. ferrooxidans and was able to grow oligotrophically.

Direct zinc sulphide bioleaching by Thiobacillus ferrooxidans and Thiobacillus thiooxidans

Biotechnology Letters, 1994
Direct bioleaching (no iron(II) present) by Thiobacillus ferrooxidans mainly occurs on the surface of the very insoluble sulphides but is more important in solution when the sulphides are more soluble. In this case, Thiobacillus thiooxidans, normally not able to leach directly insoluble sulphides, has an effective leaching action.

Growth of Thiobacillus thiooxidans on glucose

Archives of Biochemistry and Biophysics, 1966
Abstract It is possible to grow the strictly autotrophic bacterium Thiobacillus thiooxidans on glucose as the sole source of energy by means of a culture system in which the medium is continually renewed. It appears that the inability of this organism to grow on glucose under more conventional conditions is due to the accumulation of toxic ...

Oxidation of H2S in acid solution by Thiobacillus ferrooxidans and Thiobacillus thiooxidans

Process Biochemistry, 2001
Abstract Qualitative and quantitative oxidation tests of H 2 S in acid solution were carried out using Thiobacillus ferrooxidans and Thiobacillus thiooxidans species. Experiments were performed using solutions of H 2 SO 4 (pH 2.0) containing H 2 S in initial concentrations ranging from 5 to 100 ppm, in shake flasks at 150 rpm and 30°C.

Oxidative phosphorylation in Thiobacillus novellus

Biochemical and Biophysical Research Communications, 1970
Abstract A soluble cell-free fraction (144,000xg supernatent) catalyzed phosphorylation coupled to the oxidation of thiosulfate, succinate and ascorbate yielding P O ratios of 0.96, 1.9, and 0.76 respectively. However with NADH as the electron donor, the P O ratios were very low and ranged between 0.2 – 0.3.

Occurrence of Rhodanese in a Species of Thiobacillus

Nature, 1958
THE enzyme rhodanese which catalyses the reaction: has been shown to be present in Thiobacillus thiocyanoxidans. Cells of the organism, grown in thiosulphate medium with forced aeration and 2–5 per cent of carbon dioxide added1, were harvested in a de Laval centrifugal separator ...

Oxidation of Thiosulphate by Thiobacillus thioparus

Nature, 1959
PREVIOUS investigations of the oxidation of thiosulphate by the autotrophic micro-organism Thiobacillus thioparus have not led to uniform results. According to Starkey1, thiosulphate is oxidized directly to sulphur and sulphate, and Parker and Prisk2 have also come to a similar conclusion.

Murein Structure of Three Different Species of Chemolithotrophic Sulfur Bacteria: Thiobacillus tepidarius, Thiobacillus neapolitanus and Thiobacillus versutus

1993
The genus Thiobacillus is an extremely heterogeneous group of bacteria. The only criterion for placing all the species in a single genus is that they all obtain energy for autotrophic growth from the oxidation of inorganic sulfur substrates. Some species are obligately chemolitotrophic and autotrophic (e.g.
