Effect of trace elements on the rate of carbon production in marine phytoplankton at different temperature.

S. Srisudha, and P.V. Ramachandran Nair

The alteration ih trace metal (Cu. Mu and Zn) toxicity was assessed in terms of rate of carbon production at different temperature in two unicellular algae Synechocystis salina, Wislouch and Isochrysis galbana Parke. The rate of carbon production was maximum at lS°C for S. salina and at 30°C for I. galbnna. Metal toxicity increased at higher temperature (40°C) by inhibiting carbon production to a larger extent.
