Abstract
Cu2+ accumulation by S. cerevisiae resulted in rapid release of 70% of cellular K+, followed by a slower release of approximately 60% of cel lular Mg2+, but little loss of Ca2+. Co2+ was accumulated in smaller q uantities and caused a smaller loss of physiological cations than eith er Cu2+ or Cd2+. Mg2+ release during copper accumulation was maximal a t pH 6. Mg2+ release during Cu2+ accumulation increased with temperatu re and salinity of the suspension.
