Interaction of Zinc with Asterionella japonica.

Volume 24 Issue 1&2

Firyal H. Ibrahim

Abstract

Asterionella japonica cultures grown in the presence of 0, 0.5, 1.0 and 2.0 mg of Zn/L were capable of concentrating zinc and the amount accumulated is directly proportional to the concentration of metal present initially and is dependent upon the pH of the medium. No accumulation occur in the dark, at 4°C, or in dead or in dead cells. 10-3 EDTA was found to restore the growth rate to normal.
