BACTERIAL STRAIN, CUTIPAY, ISOLATED FROM THE SULFOBACILLUS THERMOSULFIDOOXIDANS SPECIES, BACTERIAL INOCULUM COMPRISING SAME, AND METHOD FOR THE BIOLEACHING OF MINERALS WHERE SAID BACTERIAL INOCULUM IS INOCULATED

摘要

The invention relates to a bacterial strain isolated from the species Sulfobacillus thermosulfidooxidans, named Cutipay, deposited in the DSMZ (under the denomination DSM 27601 on July the 29^th, 2013); This strain is useful in mining bioleaching processes, as it is highly resistant to the toxic element chloride ion. The invention also relates to a bacterial inoculum to be used in the leaching of metal sulfide ores or metal concentrates, comprising Sulfobacillus thermosulfidooxidans DSM 27601 strain Cutipay; and a method for bioleaching of ores where an ore is provided, which is selected from a metal sulfide ore or metal concentrate. Said ore is subsequently inoculated with the bacterial inoculum of the invention, and maintained at a pH of between 1 and 4, and at a temperature of between 10 and 60° C.
