摘要：

Heavy metal release to the environment has been increasing continuously as a result of industrial activities and technological development and poses a significant threat to the environment, public and soil health (Cerbasi and Yetis, 2001). Contamination of agricultural soil with heavy metals is a major problem on industrial and defense related sites all over the world. Saccharomyces cerevisiae biomass plays an important role in the investigations in the field of heavy metal biosorption. It can accumulate metal ions in biomass (Volesky and Phillips, 1995). The purpose of the present study is to examine the tolerance of S. cerevisiae strains to toxicity of Cu2+, Cd2+, Pb2+ or Ni2+. Secondly, to study how alkaline metals (Ca2+, Mg2+ or K+) correct the negative effects of heavy metals on yeast growth.
