摘要：

We report the extracellular synthesis of silver nanoparticles (Ag NPs), by using Pseudomonas aeruginosa (MTCC 424), and their significant antimycotic activity against the common plant pathogenic fungi Fusarium moniliforme (MTCC 1848) and Phoma glomerata (MTCC 2710). Detection of synthesized Ag NPs was carried out using UV-Visible spectrophotometer analysis, which showed a peak at 436 nm due to surface plasmon vibration, indicating the formation of nanoparticles. Fourier Transform Infrared Spectroscopy (FTIR) analysis and Transmission Electron Microscopic (TEM) analysis confirmed the formation of spherical nanoparticles in the range of 40-60 nm. The extracellular synthesis of silver nanoparticles by using bacteria has an advantage in the downstream processing and large scale synthesis of Ag NPs. The formation of bacterium-mediated nanoparticles is eco-friendly and economically viable process. These synthesized nanoparticles showed the significant antifungal activity against plant pathogenic fungi. Thus it is a novel approach to control the plant pathogens by using synthesized Ag NPs containing novel antifungal formulations. Copyright © 2012 American Scientific Publishers.
