Released phycobilin fluorescence reached maximum intensity less than a minute after lysis, then declined over 2 to 6 min.
However the chlorophyll a and protein content was high in blue light but the phycobilipigment was high under red light reflecting the necessity of high wavelength for the Phycobilin pigment synthesis especially PC and APC.

This is what happens in the rhodophytes and cyanobacteria, which use the nitrogen of their phycobilin pigments for cell growth if there are no external sources of nitrogen compounds.
Only phycobilins found in some cyanobacteria can absorb radiation in this segment of the solar spectrum.
