Fixation of CO2 and incorporation of thymidine under heavy metal stress inClosterium moniliferum

  • P. S. Sastry

The unicellular green algaClosterium moniliferum was sensitive to the action of divalent Ni, Cu, Hg and Cd chlorides both in CO2 fixation and in thymidine incorporation into DNA. At 0.08 ppm, Cd2+ was the most potent inhibitor (86 % inhibition of both processes), followed by Hg2+ and Cu2+, and finally by Ni2+, thymidine incorporation being generally more affected than CO2 fixation.
