Access from EThOS:
A study has been made on the effect of zinc, calcium and copper on the growth and 14C fixation of Phaeodactylum tricornutum and Dunaliella primolecta. Experiments were carried out to examine the uptake of 65Zn by Phaeodactylum and Dunaliella in laboratory culture, to investigate the processes involved, its relationship to metabolism, and the factors affecting it. Also, experiments were carried out to investigate the effect of these metals on chlorophyll concentration and protein content of Phaeodactylum and Dunaliella. It has been found that the organisms displayed varying degrees of tolerance to the presence of the metals zinc, cadmium and copper in the growth medium. Of the three metals copper was found to be more effective upon the growth, 14C fixation, zin-65, chlorophylla concentration and protein content of Phaeodactylum and Dunaliella.
