Detection of plasmids encoding copA genes in copper-resistant bacterial isolates. A. Agarose gel electrophoresis of plasmids isolated from Sphingomonas sp. strain O12 (lane 2) Sphingomonas sp. strain A32 (lane 3), Sphingomonas sp. strain A55 (lane 4) and Stenotrophomonas sp. strain C21 (lane 5). No plasmid was observed in Arthrobacter sp. strain O4 (lane 6). C. metallidurans strain MSR33 that carries the pMOL30, pMOL28 and pTP6 plasmids was used as a positive control (lane 1). B. Detection of copA gene in plasmids of bacterial isolates. The copA gene was detected in Sphingomonas sp. strain O12 (lane 2), Sphingomonas sp. strain A32 (lane 3), Sphingomonas sp. strain A55 (lane 4) and Stenotrophomonas sp. strain C21 (lane 5). C. metallidurans strain MSR33 (lanes1) was used as a positive control.
