The invention relates to bacterial strains isolated from Acidithiobacillus, which can bio-leach mineral sulphides at low temperatures. Said strains can grow at temperatures of between 5 and 10 °C and can adhere to solid supports, separately or together, forming a bio-film. The Acidithiobacillus strains, known as Puri BH20, Yaku BH19 and Urna BH12, are deposited at DSMZ (Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, Braunschweig, Germany) under accession numbers DSM 25319, DSM 25318 and DSM 25298, respectively. The invention also relates to a process for the continuous generation of a bacterial inoculant for a process for the bio-leaching of sulphurous minerals in heaps or dumps at low temperatures. |
