Preliminary characterization of a novelSynechococcusisolate showing mercury, cadmium and lead tolerance.

Abstract
A novel Synechococcus isolate, from an industrial effluent, exhibits significantly higher Hg++, Cd++ and Pb++ tolerance when compared with a wild type Synechococcus cedrorum strain. The upper tolerance levels of the isolate with Hg++, Cd++ and Pb++ were respectively (ug ml‐1) 10,60 and 60.
