How many ATP per O2?

Greetings netters
Does anyone know, in cyanobacteria, how many ATP
molecules are being produced for every O2 molecule being
produced in PSII? I know the theoretical numbers (e.g. 4H+/
ATP, 12H+/O2), but wont the actual numbers divert by the
use of the PMF for other things and by the PSI:PSII high ratio
in cyanobacteria? A reference would be highly appreciated as
Thanks Yoram
