Incidence of new bacterial species resistance to copper and antibiotics in smeltery industrial wastewater in Isfahan

Aim and Identification of strains resistant to the toxic metal is an effective step in the process of bioremidation. This study aimed to determine the minimum inhibitory concentration (MIC) of bacteria resistant to copper and some antibiotics bacteria isolated from copper smiths’ workshop in Isfahan.
In this study, the minimum inhibitory concentration (MIC) of bacteria was determined against copper and then the final identification colony- PCR was performed using the technique and evaluted copper -resistant bacteria and resistance against several .
•:Among the resistant bacteria isolated highest MIC (2 mM) of the copper from waste copper were determined. Resistant bacteria including antibiotic-resistant strains of Stenotrophomonas maltophilia, which was than most.
•: Due to the large number of bacteria resistant to antibiotics and resistant bacteria at the same time as the copper, unfortunately, these bacteria can in the future be used for the biosorption of copper from the environment unless they removed the gene for antibiotic resistance.
