The present study is focused on rapid mycosynthesis, characterization, and potential applications of silver nano particles (AgNPs).A novel fungal strain Beauveria sp. MTCC 5184 was incubated in 1% glucose media for 48 hours, and the cell-free broth was used for nanoparticle synthesis. The presence of possible biomolecules that are accountable for the formation and capping of AgNPs was detected in FTIR analysis. AgNPs showed an absorption peak at 439 nm, and TEM images illustrated the smaller size of the nanoparticles with variable shapes. The powder XRD patternindicated five diffraction peaks at 2θ values 38.28o, 44.48o, 64.76o, and 77.69o, which correspond to the (111), (200), (220), (311), and (222) planes of facecentered cubic.DLS analysis illustrated an average particle size of 58nm and zeta potential of 11.57mV. Further in functional characterization, AgNPs and sodium bromide showed promising dye-reducing ability against two textile dyes, Reactive Blue HERD and Orange M2R cold brand. Individual dyes anda mixture of both dyes wereshown to reduce by 99% at the concentration up to 80 ppm at neutral pH.AgNPs showed strong antibacterial activity towards various entero-pathogens by well diffusion method. The findings suggest that using 1% glucose media for the growth of new fungal species is enough to synthesize silver nanoparticles with potential applications. |
