Studies on thiobacillus denitrificans

Archiv f�r Mikrobiologie, 1954
Experiments with T. denitrificans have shown that this bacterium cannot develop in media devoid of ammonium salts, and that iron is required for growth. Pure cultures have been isolated by means of a modified medium which permits rapid growth in serial transfers.

Preservation of Thiobacillus ferroxidans and Thiobacillus thiooxidans with activity check

Antonie van Leeuwenhoek, 1986
Cultures of Thiobacillus ferrooxidans and Thiobacillus thiooxidans, used in biohydrometallurgical processes of economic importance, are very difficult to preserve by conventional methods. Hence, to preserve the cultures with their activity intact, various techniques were tried, after determining their respective activity in terms of Iron Oxidation Rate

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.

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.
