Microalgae are microscopic photosynthesis organisms that are found in both marine and fresh environments.The aim of this research work is to investigate the antimicrobial activity of Silver Nanoparticles from microalgae Spirulina Platensis by green synthesis. The green synthesis shows the greater potential biomedical applications of silver nanoparticles.Average crystallite size of silver nanopartivles was observed to be 25.30nm by X ray Diffraction (XRD).The antimicrobial activity of silver nanoparticles was found in gram positive bacteria (Bacillus subtilis,Bacillus pulamis,Aspergillus flavous, Staphyloccus aureus and Gram negative bacteria( Klebsiella pneumonia Escherichia coli and Pseudomonas flurescencens) and Candida albicans strain. Among these strains,Candida albicans indicated the highest antimicrobial activity of Spirulina Platensis.
