Abstract

Mycosynthesis deal with an energy-saving and eco-friendly process intended for extracellular synthesis of AgNPs, by means of cell-free filtrates of fungi Aspergillus niger and Fusarium semitectum as reducing agents. Optimization of different parameters during biosynthetic process demonstrated diverse property on production rate, the size, distribution, yield of biosynthesized AgNPs. SEM micrographs showed polydisperse spherical and ellipsoid nanoparticles (SIZE). AgNPs exhibits potential antimicrobial effect than Ag+ not in favor of E. coli, Staphylococcus aureus, and Pseudomonas aeruginosa. These results demonstrate that mycosynthesis of AGNPs is a cost effective and eco-friendly method, resulting in particles with antibacterial properties that are efficient as an antimicrobial agent.•Characterization of Silver nano particle is widely applauded domain at present.•Mycosynthesis of AgNPs as reducing agents and exhibits potential antimicrobial effect.•Results of mycosynthesis of AgNPs is cost effective and ecofriendly.

Method ArticleABSTRACT Mycosynthesis deal with an energy-saving and eco-friendly process intended for extracellular synthesis of AgNPs, by means of cell-free filtrates of fungi Aspergillus niger and Fusarium semitectum as reducing agents
Fungal strains Aspergillus niger was grown in czapadox broth, where as Fusarium semitectum was grown in glucose nutrient broth medium (GNB), with adjument of pH 7.0
The fungi Fusarium semitectum and Aspergillus niger were used for the production of stable AgNPs and were scrutinized visually by turning the fungal aqueous filtrate incubate with AgNO3 solution into dark brown due to the deposition of AgNPs due to the surface plasma resonance

AgNPs exhibits potential antimicrobial effect than Ag+ not in favor of E. coli, Staphylococcus aureus, and Pseudomonas aeruginosa. These results demonstrate that mycosynthesis of AGNPs is a cost effective and eco-friendly method, resulting in particles with antibacterial properties that are efficient as an antimicrobial agent. Mycosynthesis of AgNPs as reducing agents and exhibits potential antimicrobial effect. Results of mycosynthesis of AgNPs is cost effective and ecofriendly.
