摘要：

Copper abstraction from aqueous solutions by Streptomyces pilosus was studied. Comparison of the amount of metal accumulated by living and killed cells as well as by isolated cell wall preparations, indicated that the cell interiors of the organism play an important role in the Cu (II) ions biosorption process This was confirmed by electron microscope and EPR examinations. The EPR spectra showed that accumulated copper formed complexes with CuO4 and CuO2N2 or CuO3N chromophores. These complexes were found in the whole cells (live and dead). However, in the case of isolated cell walls, the complex with CuO2N2 or CuO3N chromophore was absent.
