  • Sulfur-oxidizing bacteria and their use in bioleaching processes for sulfured copper minerals
    Patent number: 8372628
    Abstract: The present invention is related to an isolated chemolithotrophic bacterium belonging to species Acidithiobacillus thiooxidans named Licanantay, deposited in Deutsche Sammlung von Mikroorganismen and Zellkulturen GmbH-DSMZ with number DSM 17318, and its use in pure form or in mixtures that contains it for bioleaching processes of minerals or sulfured metallic species concentrates. This Licanantay strain DSM 17318 has sulfur-oxidizing activity in both primary and secondary sulfured minerals, especially in the case of chalcopyrite, covellite, bornite, chalcocite, enargite and tennantite.
    Type: Grant
    Filed: January 25, 2010
    Date of Patent: February 12, 2013
    Assignee: Biosigma S.A.
    Inventors: Atsuko Ohata, Manabu Manabe, Pilar A. Parada Valdecantos
