LI Mingchun JIANG Heng HOU Wenqiang XING Laijun (Deparment of Microbiology, Nankai University, Tianjin, 300071)  
Biosorption of 33 strains of live yeasts or nonliving yeasts in six genera to heavy metal ions Cu 2+ 、Cd 2+ 、Ni 2+ was primarily studied. The result shows that the uptake time, temperature, pH, the presence of other metals, mycelial ages and live or dead cells have obviously affected on biosorption. Under the condition of optimum combination, a Candida sp. was found, having uptake capacity order of Cd 2+ Cu 2+ Ni 2+ to the three metals adsorbability of per gram live cells is 17.23mg10.57mg3.2mg respectively. Adsorbability of dry cells is obviously lower than that of live cells to the three heavy metals.
