Growth of Thiobacillus ferrooxidans: a novel experimental design for batch growth and bacterial leaching studies
Article Abstract:
The growth of Thiobacillus ferroxidans was studied using a novel experimental design for batch growth and bacterial leaching studies. To report the development a new experimental technique for kinetic studies of bacterial leaching, the batch experiment determined the redox potential of the solution which is dependent on the ratio of concentrations of ferrous and ferric ions by applying electrolysis. Results show that electrolysis does not affect the growth of the bacteria. The apparatus can, however, be used to identify the role of bacteria and iron in a leaching reaction.

Coal depyritization by the thermophilic archaeon Metallosphaera sedula
Article Abstract:
Pyrite oxidation by Metallosphaera sedula with moderate and high pyritic sulfur content showed that it oxidized mineral pyrite at an enhanced rate.The magnitude of biological stimulation above abiotic rates was significantly less than with mineral pyrites, and the maximum rate of coal depyritization were also enhanced by Metallosphaera sedula. The oxidation of pyrite with ferric ions diminishes coal depyritization, and this has been significantly noticeable due to the maintenance of a high ratio of ferric to ferrous iron in solution by Metallosphaera sedula.
