Selective accumulation of silver by fungi

APhoma sp., tolerating 1 mmol/l Ag+, and 32 other fungi from a culture collection (not selected for their metal tolerance), were tested for their ability to accumulate silver, cadmium, copper, nickel and lead ions from aqueous solutions. Silver was accumulated selectively. Bivalent ions Cu, Cd, Ni and Pb were partially released after about 50 min, whereas the monovalent Ag ion remained bound. The selectivity of thePhoma sp. for silver developed in the late linear growth phase and might be connected with the occurence of a slimy exopolymer. The mean accumulation of the five heavy element ions by 32 strains of fungi could not be correlated with the ionic radii of the ions.
