Abstract

The use of microorganisms in the synthesis of nanoparticles emerges as an ecofriendly and existing approach. In this study biosynthesis of silver nanoparticles using Streptococcus sp, Proteus sp, Pseudomonas sp and its antimicrobial activity against (S.typhi, S.epidermidis, K.pneumoniae,P.aeruginosa, P.vulgaris, E.coli) different pathogen has been reported. The zone of inhibition seems in both gram positive and gram negative bacterial strains.
