摘要：

The interactive effects of cadmium (Cd) and calcium (Ca) on growth, photosynthesis (O-2 evolution), nitrogenase, respiration, developmental cycle and Cd bioaccumulation by the N-2 fixing cyanobacterium Nostoc UAM208 have been studied. Ca was found to exert a detoxifying role towards Cd inhibition of these physiological processes. Finally, the mechanisms by which Ca might protect the cyanobacterium against Cd toxicity are discussed.
