Abstract:
A novel bioassay system for estimating concentrations of several heavy metal ions was carried out with yeast mutants which are highly sensitive to heavy metal ions. The method does not need an atomic adsorption spectrometer or other special equipment. It is suitable for screening of microorganisms that efficiently remove heavy metal ions from aqueous solution.
