How a cyanobacteria harness the power of photosynthesis, and nitrogen fixation simultaneously?

How a cyanobacteria harness the power of photosynthesis, and…

Right after my internship in Germany, I collaborated with Dr. Irene Rodriguez, and Dr. Tung-Yuan Ho for 3 months to do intensive research in our project about the role of metalloenzyme Ni-SOD in diel nitrogen fixation, and photosynthesis of filamentous diazotroph Trichodesmium.  Nitrogen fixation cannot occur with the presence of oxygen but this tiny creature somehow manage to do it while going through photosynthesis, an oxygen production process. How did they do it? I used immunocytochemistry, confocal microscopy, and image analysis to find more information about it in cellular level, which are also relatively new techniques in Marine Biogeochemistry field.
