Abstract :
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.
