Heavy metal induced changes in the spectral properties ofAnacystis nidulans

Copper caused bleaching of phycocyanin changing the pigment-protein interaction. On cadmium treatment the energy was not efficiently transferred to photosystem (PS) 2 and a spillover of energy occurred to PS1. Thallium treatment induced a general decrease in absorption and fluorescence of chlorophyll and phycobilisomes, whileAnacystis was resistant to lead.

Keywords: blue green algae; cadmium; carotenoids; chlorophyll; copper; lead; thallium
