Subcellular distribution of accumulated heavy metals in Saccharomyces cerevisiae and Kluyveromyces marxianus

Heavy metal accumulation by microorganisms is an attractive option for treatment of contaminated water and metal recovery from waste.

Description
Summary:Heavy metal accumulation by microorganisms is an attractive option for treatment of contaminated water and metal recovery from waste. Kluyveromyces marxianus and Saccharomyces cerevisiae were tested for distribution of accumulated bound metals (silver, cadmium, and copper) in cytoplasm and cell surface/vacuoles. Absorption by insoluble cellular fractions is the main mechanism of metal accumulation in both organisms, although accumulation by S. cerevisiae was less effective than by K. marxianus.
