Adaptation of Pseudomonas aeuroginosa to Copper Ore During Bioleaching

In this study, adaptation of Pseudomonas aeruginosa to copper during bioleaching was investigated. In the first method, 5g of copper oxide ore were added to the culture medium and the solution was incubated. After two weeks, the bacteria were separated from the solution and cultured in an appropriate medium. In the second method, serial subculturing with 2, 4, 8, 16 g of ore was performed. Then, bioleaching by adapted bacteria was carried out with optimum bioleaching parameters obtained from a previous study. According to the results, Pseudomonas aeruginosa had high tolerance to the copper oxide ore and adapting cells to copper ore did not improve copper extraction.
