Cu uptake in the diazotrophic cyanobacteriumNostoc calcicola Bréb. was accompanied by inhibitions in the in vivo activities of photosystem (PS) II, PS I,14CO2-fixation, and decline in the ATP pool. Cyanobacterial cells, while saturated for Cu uptake within 1 h at 40 μM Cu, showed more than 50% inhibition of PS II and 95.4% of14CO2 fixation compared with(More)
