متن کاملThe Use of Thiobacillus Ferrooxidans Bacteria in the Process of Chalcopyrite Leaching
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...

Mahoney, Robert P. (Skidmore College, Saratoga Springs, N.Y.), and Mercedes R. Edwards. Fine structure of Thiobacillus thiooxidans. J. Bacteriol. 92: 487-495. 1966.-Thin section analysis of the chemosynthetic autotroph Thiobacillus thiooxidans revealed structures comparable to gram-negative heterotrophic bacteria. Although this species is unique in that it oxidizes elemental sulfur for energy, ...
متن کاملdesulphurization of coal by using of thiobacillus ferrooxidans and thiobacillus thiooxidans bacteria
a new solution aiming at coal biodesulphurization has been developed based on the use of bacteria. the most frequently used species of bacteria for removal of inorganic sulphur compounds are thiobacillus ferrooxidans, thiobacillus thiooxidans and thiobacillus acidophilus. in this study the coal sample was decomposed initially and desulphurization experiments was carried out in pure and mixed cu...
متن کاملA Study of Thiobacillus thiooxidans with the Electron Microscope.
Thiobacillus thiooxidans, an obligate autotrophic sulfur-oxidizing bacterium, has received considerable attention because of the interest and importance attached to a knowledge of its physiology. In the original description of the organism (Waksman and Joffe, 1922) was included a photomicrograph the essential features of which are reproduced from our own cultures in figure 1. We have recently h...
