The result shows that it is better to choose T·thiooxidans and the more quantity of the sulfur.

Research Progress in the Application of Thiobacillus and Elemental Sulphur for the Remediation of Heavy Metals Contaminated Soil and Sediments;

The results showed that aerobic strain was classified as Thiobacillus and anaerobic strain as Desulfotomaculum.

Bioleaching of heavy metals from thickened wastewater sludge with different substrates was studied with indigenous Thiobacillus isolated from native sludge and enriched by selected mediums.

Effect of Thiobacilli on the Leaching of Heavy Metal from Solidified Sludge;

4% for Cu, Zn, Cd, Cr, Ni and Pb respectively, and the sulfate, as a result of sulfur oxidation by indigenous thiobacilli of sludge, .

The influence of bioleaching effect of heavy metals in sewage sludge with mixing of two substrates (pyrite and elemental sulfur) was studied adopting a batch test with inoculation of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans.

The strain of Acidithiobacillus spreading in sulfide deposits, acid mine water and soil is a gram-negative, extremely acidophilic obligately autotrophic bacterium.

Use of Xanthomonas sp He4 and Thiobacillus thioparus Au16 Immobilized in the Trickle-bed Biofilter to Remove Ethanethiol;

The biodegradable organics are removed in thefirst stage and sodium thiocyanate is degraded in the second stage with an obligate biofilmpredominated by autotrophic thiobacillus thioparus.

Improving the species of T.ferrooxidans with the method of protoplast fusion;
