Study of Possibility of Using Yeast (Saccharomyces cerevisiae) as Biosorbent of Heavy Metals of Industrial Sewage

Basic principles, stages and conditions are considered at which the maximal biosorption of heavy metals by yeast occurs. The conducted study has touched upon a stage of finding the threshold yeast concentrations in liquid medium with introducing salts of metals Zn, Ni and Cu in it. A stage of study of yeast biosorption properties in sewage with the increased content of heavy metals is also presented. Basic regularities of biosorption depending on the medium conditions are revealed.
