No, the species of Oscillitoria we have does NOT fix N2 gas, it simply does not have too. There is plenty of NO3/NH4 around relative to their size and biomass. Plants need far more NO3/NH4 than BGA's.

I addressed this on the APD several years ago(4?) and elsewhere since.
Speculations and inaccurate use of references leads to myths.
