Ten Actinomyctes were isolated. FourStreptomyces spp. isolate were diagnosed. Theses isolates were examined for production of slivernanoparticle. Streptomyces spp.2 isolate were able on sliver nanoparticle production. AllStreptomyces spp. isolates having Aerial Mycelium grey in color and Yellow-green SubstrateMycelium. Streptomyces spp.2 was selected for study characterization of sliver nanoparticleproduction. These isolate was grey aerial mycelium and yellow-brown substrate mycelium,glucose and sucrose using ,negative for mannitol and mannose. The characteristics of slivernanoparticle was studied. The UV spectrum showed maximum absorption(λ max) at 422 nm. TheFT-IR spectrum analysis for AgNPs represented absorption peak at 3402 cm-1 which refer to OHgroup,3080 cm-1 refer for C-H aromatic group,2924 indicate for presence of C-H aliphaticgroup,1749,1724 cm-1 indicate to C=O group (carbonyl group), 1651 indicate to presence C=Cgroup,1375 indicate to presence of C-O-C, 794 indicate to presence C-Cl or C-Br. BiosynthesizedAgNPs are spherical in shape with size (78.96 nm ) and having purity (75.09%)as examined byEDXA combined with FE-SEM.
