A simple route for the synthesis of silver nanoparticles by Spirulina platensis (cianobacteria) and Streptomyces spp. 211A (actinobacteria) has been demonstrated in this work. The silver nitrate solution incubated with bacteria biomass changed to a yellowish color, indicating the formation of silver nanoparticles. Spectroscopic analysis demonstrated that tested solutions yielded the maximum absorbance peak at 425 nm due to silver nanoparticles. Also, X-ray analysis of the bacterial biomass confirmed the formation of silver nanoparticles.
