Seven selected cyanobacterial species namely Nostoc linckia, Nostoc muscorum, Oscillatoria acuminata, Anabaena variables, Oscillatoria amphigranulata, Spirulina platensis and Phormidium purpurascens were cultivated on suitable media. In this work, the growth rates of were measured by optical density and dry weight, day after day. Spirulina platensis biomass was harvested at the 16th day which about equaled 8.322 g/L dry biomass. Also the biomass of other selected cyanobacterial species was collected at the 22nd day. The present work was designed for the biosynthesis of AgNPs by seven cyanobacterial species using their filtrate and biomass separately. Appearance of surface plasmon band at 400 nm for filtrate and biomass indicated the biosynthesis of AgNPs. UV-vis spectroscopy used to characterize biosynthezied AgNPs and resulted in appearance of surface plasmon band at 400 nm for filtrate and biomass
