I've found that cyanobacteria do contribute organic nitrogen to the system.

The process involves the cyanobacteria rapidly consuming nutrients until
they become nutrient limited in some way other than nitrogen.  At this
point, they begin to die off and decay, contributing their nutrients back
to the system.
