Abstract
The effect of concentrations of Zn [a major environmental pollutant] from 50-400 mg/l on the growth of S. bacillaris and C. vulgaris under laboratory conditions was examined. The growth of both species was inhibited in proportion to the concentration of the metal in the medium. S. bacillaris was more tolerant to high Zn concentrations than C. vulgaris. Microscopical examination of cells growing in medium with Zn did not reveal any significant changes compared to the control cultures.
