  • Microbial mutualism in leaching of CuNi sulfide ...

    In the present paper, the authors report their test work with a Cu-Ni sulfide concentrate and show that the mutualistic association of T. ferrooxidans with nitrogen-fixing bacteria Beijerinckia lacticogenes helps leach more metal faster in a leaching medium devoid of any added carbon or nitrogen source. Use of intentionally mixed bacterial culture in ore

    Other articles where Thiobacillus is discussed: Thiobacillus oxidizes thiosulfate and elemental sulfur to sulfate, and A. ferrooxidans oxidizes ferrous ions to the ferric form. This diverse oxidizing ability allows A. ferrooxidans to tolerate high concentrations of many different ions, including iron, copper, cobalt, nickel, and zinc. All of these types of

    At. ferrooxidans binds to a metal sulfide substrate by way of an extracellular polymer matrix. The redox cycling conducted in the matrix helps to sustain the bacterium. (Valdés et al. 2008) There has been much debate over how At. ferrooxidans contributes to the conversion of metal ores into soluble compounds. Although it has been proposed that

    Some members of this genus were classified as Thiobacillus spp., before they were reclassified in 2000. Acidithiobacillus ferrooxidans (basonym Thiobacillus ferrooxidans) can be isolated from iron-sulfur minerals such as pyrite deposits, oxidising iron and sulfur as energy sources to support autotrophic growth and producing ferric iron and sulfuric
