The development of appropriate processes for the synthesis of nanoparticles is an important aspect of nanotechnology. In this study, fungus mediated synthesis of silver nanoparticles using Microporus Xanthopus has been done. The dried macro fungi were powdered and boiled for 20 minutes to get the extracts. The extracts were treated with silver nitrate and kept in the dark conditions for 48 hrs, for the appearance of colour change. The Plasmon peak was observed at 425 nm. These nanoparticles were examined for the stability for a period of 2 months and were further characterized by SEM and FTIR. SEM analysis revealed the spherical nature of silver nanoparticles and size distributed in the range of 40 nm. However further studies regarding XRD, SEM, EDX, are confirmed to strengthen the existing findings. The synthesized silver nanoparticles have been investigated against the pathogenic bacteria Bacillus subtilis , Staphylococcus aureus, Pseudomonas aeruginosa , Escherichia coli , Klebsiella pneumoniae and shigella sp for their antibacterial activity and minimum inhibitory concentration
