The isolation and use of iron-oxidizing, moderately thermophilic acidophiles from the Collie coal mine for the generation of ferric iron leaching solutionP H M Kinnunen
Institute of Environmental Engineering and Biotechnology, Tampere University of Technology, PO Box 541, 33101 Tampere, Finland
Appl Microbiol Biotechnol 60:748-53. 2003..3 g Fe(2+) l(-1) x h(-1). These rates compare favourably with the iron-oxidation rate of Acidianus brierleyi in shake-flasks, but are considerably lower than mesophilic iron-oxidation rates...
High-rate ferric sulfate generation by a Leptospirillum ferriphilum-dominated biofilm and the role of jarosite in biomass retention in a fluidized-bed reactorPäivi H M Kinnunen
Institute of Environmental Engineering and Biotechnology, Tampere University of Technology P O Box 541, FIN 33101 Tampere, Finland
Biotechnol Bioeng 85:697-705. 2004..71.10(9) cells g(-1)), 31% (or 3.12.10(10) cells g(-1)) and 10% (or 1.24.10(8) cells mL(-1)) of the total FBR microbes, respectively, demonstrating that the jarosite precipitates played an important role in the FBR biomass retention...
Characterization of iron- and sulphide mineral-oxidizing moderately thermophilic acidophilic bacteria from an Indonesian auto-heating copper mine waste heap and a deep South African gold minePäivi H M Kinnunen
Institute of Environmental Engineering and Biotechnology, Tampere University of Technology, PO Box 541, 33101 Tampere, Finland
J Ind Microbiol Biotechnol 31:409-14. 2004..Chalcopyrite concentrate supported a simpler and different community than Fe2+. The members of the enrichment cultures were closely related to Sulfobacillus yellowstonensis and Sulfobacillus acidophilus...
Chalcopyrite concentrate leaching with biologically produced ferric sulphateP H M Kinnunen
Institute of Environmental Engineering and Biotechnology, Tampere University of Technology, P O Box 541, FIN 33101 Tampere, Finland
Bioresour Technol 97:1727-34. 2006..CuFeS2, Ag and Cu1.96S potentials indicated the formation of a passivating layer, which consisted of jarosite and sulphur precipitates and which was responsible for the decreased leaching rates...
Characterization of a thermophilic sulfur oxidizing enrichment culture dominated by a Sulfolobus sp. obtained from an underground hot spring for use in extreme bioleaching conditionsVirpi L A Salo-Zieman
Institute of Environmental Engineering and Biotechnology, Tampere University of Technology, 33101 Tampere, Finland
J Ind Microbiol Biotechnol 33:984-94. 2006..Both granular and powdered forms of sulfur were bioavailable, but the oxidation rate of granular sulfur was less than 50% of the powdered form. Chalcopyrite concentrate oxidation (1% w/v) by the VS2 resulted in a 90% Cu yield in 30 days...
