Cyanobacteria synthesizing cyanophycin use it as a source of nitrogen during nitrogen limitation  and cyanophycin is typically composed of arginine, aspartic acid and glutamic acid .
It is also confirmed through studies that in most of the cyanobacteria including non-heterocystous forms, cyanophycin acts as a reservoir of nitrogen [37, 38].
