Application of Novel Biogenic nanoparticles for antimicrobial traits

Nanotechnology is a better approach to dealing with the current challenges of phytopathogens in agriculture and the environment. Nanoparticles (NPs) are less time-consuming, non-toxic and environmentally friendly and provide a high yield compared to conventional synthesis of NPs. Using plant growth promoting (PGP) bacterial strain for the synthesis of nanoparticles can route out the challenges of using chemical-based fertilizers and pesticides for agriculture. In our study, silver nanoparticles (AgNPs) were synthesized by using Burkholderia sp. 15B, which were further characterized by various physical techniques. All the techniques suggested the formation of biogenic NPs. We found that the bacteria-based NPs were able to hamper the growth of phytopathogenic fungi by more than 80%, as examined by the inhibition of fungal growth in the presence of green NPs. In addition, the synthesized NPs efficiently rescued seedlings from phytopathogenic fungal invasion. The results implicate the use of microorganism-mediated AgNPs as pesticides over chemical-based pesticides.
