The effect of glutaraldehyde (GA) in different concentrations on microbiological activities of Bacillus licheniformis, Desulfotomaculum ruminis and Thiobacillus ferrooxidans bacteria used in the processes of denitrification, desulfurication and iron (II) oxidation, respectively, has been tested. For the sake of comparison, the effect of formaldehyde (FA) on the activities of the same organisms ...

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...

Authors Response to the Comments by Reviewer 3 General comments Reviewer’s Comment: The manuscript “Pyrite Oxidation under initially neutral pH conditions and in the presence of Acidithiobacillus ferrooxidans and micromolar hydrogen peroxide” submitted by Y. Man and C. Lin, is interesting in so far as the studies about this issue are relatively scarce. However, in my opinion, selected pyrite cu...

In vivo force microscopy measurements of Acidithiobacillus ferrooxidans revealed a repulsive force that was due to the presence of extracellular polymers on the bacterium's surface. Measured force-distance profiles were fit to steric force theory to estimate the density and thickness values of these exopolymers. The polymer densities were 3.4 x 10(16) to 7.1 x 10(16) molecules m(-2), and the eq...

Acidithiobacillus ferrooxidans YQH-1 is a moderate acidophilic bacterium isolated from a river in a volcano of Northeast China. Here, we describe the draft genome of strain YQH-1, which was assembled into 123 contigs containing 3,111,222 bp with a G + C content of 58.63%. A large number of genes related to carbon dioxide fixation, dinitrogen fixation, pH tolerance, heavy metal detoxification, a...
