Abstract A study on the copper accumulation by resting cells of copper-resistant bacteria, isolated from activated sludge and electroplating effluent, was conducted. The best selected strain, identified as Pseudomonas putida II-11, retained copper ions, Cu(II), as high as 6.5\% of its dry weight. Bacterial cells grown in the sulphate-limiting medium had the highest copper removal capacity [RC, mg of Cu(II)/g of dry cells], while the presence of glucose or sodium azide did not affect Cu(II) RC of the bacterial cells. A possible mechanism of Cu(II) accumulation by this bacterium is suggested.
