dc.description.abstractSensitivity of four tropical cyanobacteria viz. Coelosphaerium sp., Synechococcus sp., Oscillatoria sp. and Chroococcus sp. to environmentally relevant concentrations of Cr6+, Cd2+ and Zn2+was assessed based on fluorescence change as a proxy for growth reduction. At 24 h exposure, the growth reduction inthe cyanobacteria followed the order: Zn2+ < Cr6+ ≤ Cd2+. Of the four cyanobacteria, Synechococcus was the most sensitive for Cr6+, where as Chroococcus was the most sensitive for Cd2+and Zn2+. Sensitivity was gradually decreased by 96 h implying the acquisition of tolerance by cyanobacteria to heavy metal ions with prolonged exposure.en_US
