The accumulation process of $Pb^{2＋}$ in an industrial strain of Saccharomyces cerevisiae proved to be temperature-dependent, and was quite similar to chemical adsorption at the initial stage of $Pb^{2＋}$accumulation. The initial $Pb^{2＋}$ accumulation rate increased from 11.4 to 46.2 mg $Pb^{2＋}$/g cell dry weight/day, in response to the increased temperature from $20^{circ}C;to;50^{circ}C$ while the maximal $Pb^{2＋}$ accumulation amount (175.8 mg $Pb^{2＋}$/g cell dry weight) was achieved at $30^{circ}C$. The maximal $Pb^{2＋}$/ accumulation amount with temperature was independent of ion exchange with $K^＋;and;Mg^{2+}$.
