| Abstract: | Iron induced
changes in growth , N2-fixation, CO2 fixation and
photosynthetic activity were studied in a diazotrophic cyanobacterium Anabaena PCC 7120. Iron at 50 ยตM
concentration supported the maximum growth, heterocyst frequency, CO2
fixation, photosystem I (PS I), photosystem II (PS II) and nitrogenase
activities in the organism. Higher concentration of iron inhibited these
processes. Chl a and PS II activities
were more sensitive to iron than the protein and PS I activity. |
