More Information
Summary:The present invention is related to an isolated chemolithotrophic bacterial strain belonging to the specie Acidithiobacillus ferrooxidans, named "Wenelen" and deposited at the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH-DSMZ under classification number DSM 16786, the use of said bacteria for leaching ores or concentrates containing of metallic sulfide species and leaching processes based on the use of said bacteria or mixtures that contain said bacteria. This Wenelen DSM 16786 strain has an increased oxidizing activity, especially regarding chalcopyrite, when compared to known bacteria. Due to the former feature, this bacteria strain show great interest for biomining applications and it is presently being subjected to annotation processes after sequencing.
