The relationship between cell density of Phaedactylum tricornutum and bio-accu-mulation and excretion of zinc-65 in the algae

Abstract:

The effects of different cell densities of Phaedactvlum tricornutum on bio-accumulation and excretion of ⁶⁵Zn in the algae have been studied.The experimental results show that concentration of ⁶⁵Zn in low density group of the algae from sea water is greater than that in high density group.Concentration factors of three groups are above 10⁴, and the C. F. of the lowest density-group is the greatest, 4.4×10⁴. The mechanism of accumulating ⁶⁵Zn by unicellular algae is discussed.
