Enzymes such as cytochrome c oxidase from iron (Fe 2+)-oxidizing Hg-sensitive acidophilic bacterium Thiobacillus ferrooxidans also play a role in reduction of Hg 2+ (Iwahori et al., ).Mercury sensitive dissimilatory metal reducing bacteria.

Jun; (6)– [PMC free article] Silver S, Phung LT. Bacterial heavy metal resistance: new surprises. Annu Rev Microbiol. ; –Cited by: Ten different isolates of Thiobacillus ferrooxidans were studied with regard to their degree of resistance to the metals copper, nickel, uranium, and thorium. Inhibitory concentrations for a particular metal were those which showed a statistically-significant decrease in the amount of ferrous iron oxidized by the bacterium compared to an Cited by: Plasmid-encoded resistance may provide organisms with efflux and bypass mechanisms, enzymes which catalyze the transformation of metals to volatile forms, or make the bacterial cell wall impermeable to the metal(s). A problem still remains in actually defining the concentrations that distinguish metal-resistant from metal-sensitive bacteria.

DUA. Acidithiobacillus ferrooxidans (formerly Thiobacillus ferrooxidans) is a chemolithoautotrophic bacterium that obtains its energy from the oxidation of ferrous iron, elemental sulfur, or partially oxidized sulfur compounds (19, 24).This ability makes it of great industrial importance due to its application in biomining to recover metals such as copper, gold, and uranium (19, 23).

Thiobacillus ferrooxidans, grown on either ferrous sulfate, lead sulfide concentrate, or chalcopyrite concentrate demonstrated oxygen uptake and CO 2 fixation in the presence of ferrous sulfate, chalcopyrite ore, pyrite ore, and red antimony trisulfide. Lead suifide-grown cells could oxidize lead sulfide ore and galena, using the energy obtained for CO 2 fixation.

Abstract. The iron-oxidizing bacterium Thiobacillus ferrooxidans is the most important microorganism in mineral leaching. It plays the dominant role in bioextractive processes because of its ability to oxidize both iron and reduced sulfur compounds.

These bacteria were growth in solutions after they were isolated from natural environment (J. WANG & al. [5], GOMEZ and BOSECKER [6]). The type of bacteria will influence the bioleaching yield.

The 16S rRNAsequence data and physiological characteristics ofthese "neutrophilic thiobacilli" are so different fromtypical acidophilic, obligately autotrophic T. ferrooxidans and T. thiooxidans isolates that they should not be considered to be members of the .
