Effect of light wavelength on phycocyanin and PE concentrations on Pseudanabaena/Limnothrix sp. cells and AgNPs synthesis.

LED Light	AgNPsDry Weight (mg)	PC (mg/g Biomass)	PE (mg/g Biomass)
White	6.2 ± 0.1	152.2 ± 1.0	32.1± 0.6

These results are in agreement with previous studies, which reported that PC can be used for the synthesis of spherical and elongated AgNPs [15,16].
