Comparing cyanobacteria grown with nitrate and one without. Does anyone know the structural differences and why?

well it depends on what cyanobacteria you are growing. if you are growing some species like Nostoc or Anabaena which can fix atmospheric nitrogen then it will get all the notrogen it requires from fixing N2.
If however you are growing a species of cyanobacteria that cannot fix atmospheric nitrogen(i don't know any example to give you that i am sure cannot fix nitrogen and i don't want to give wrong info) then it will show clear problems from the fact that it won't have nitrogen to make proteins and DNA. consequences on the long term - death. sort term - depends on the organism i guess...
