Agriculture industrial waste or byproducts could be a valuable biological material for synthesis of metal nanoparticles. Deoiled flaxseed meal is a byproduct of flaxseed oil industry. In present study its hydroalcoholic extract (70%) was assessed for the synthesis of silver nanoparticles. Synthesis of silver nanoparticles was confirmed and characterized by using UV-Vis spectrophotometer, X-ray diffraction (XRD), scanning electron microscope (SEM) and fourier transform infrared spectrum (FT-IR). The antimicrobial activity of silver nanoparticles was evaluated against gram-negative (E. coli), gram-positive (S. aureus) bacteria, and mycotoxin producing fungi A. flavus and A. parasiticus. The results of XRD, SEM analysis confirmed the face centered cubic structure of colloidal silver nanoparticles having particle size 9.22 nm. FT-IR analysis showed phenolic components of flaxseed hydroalcoholic extract could be responsible for the synthesis of silver nanoparticles. The resultant potent antimicrobial activity of synthesized silver nanoparticles could corroborate its usefulness in food and health product industry including flaxseed oil.

Keywords: Synthesis, silver nanoparticles, flaxseed, antimicrobial, mycotoxin producing fungi.
