Abstract

Metal accumulation by a silver-resistant Pseudomonas stutzeri AG259 strain and a Streptomyces albus strain was investigated in a mixed metal solution of silver, copper, lead and zinc. The location of silver, lead and copper on cells was determined by transmission electron microscopy coupled with an X-ray analysis system. In P. stutzeri cells silver was detected as dense deposits on the cells. Copper and lead were distributed over the cells. S. albus accumulated these metals only on part of cells with a higher concentration per cell than in P. stutzeri.
