  • Bacteria strain wenelen DSM 16786, use of said bacteria for leaching of ores or concentrates containing metallic sulfide mineral species and leaching processes based on the use of said bacteria or mixtures that contain said bacteria
    Patent number: 7601530
    Abstract: 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.

  • Thiobacillus thiooxidans growth inhibitor
    Patent number: 6146666
    Abstract: A Thiobacillus thiooxidans growth inhibitor containing as the active ingredient at least one substance selected from the group consisting of a tungsten powder and tungsten compounds. Under acidic conditions of pH value of 4 or less, this growth inhibitor sufficiently inhibits the growth of T. thiooxidans. When added in a very small amount to, for example, a structural material such as concrete in a sewage disposal plant, etc., it can therefore inhibit the growth of T. thiooxidans without substantially decreasing the strength, etc. of the structural material per se.
