Abstract

The champignon mushroom Agaricus bisporus was cultivated on compost labelled with the radioactive traers ^110m^Ag and ^203^Hg and the uptake of these two metals studied. The radiotracer then served as an aid in elucidation and characterization of the fungal metal–protein species using gel chromatography. In the case of the silver–protein complex, but not of mercury, the majority of the metal was contained in the fractions of intermediate (ca 8000–10000 Da) molecular weight possibly corresponding to metallothioneins (MT) or MT‐like species.
