Antimicrobial Applications on ficus religiosa
What's Happening
Silver nanoparticles synthesized from Ficus religiosa leaf extract exhibit potent antimicrobial activity through multiple mechanisms: disruption of bacterial cell membranes, inhibition of respiratory chain enzymes, and suppression of fungal spore germination. The 83.8 nm spherical nanoparticles with -19.9 mV zeta potential demonstrate enhanced surface area-to-volume ratio for maximum microbial interaction.
How to Fix It
- 1
Against Gram-negative bacteria (E. coli): Apply AgNPs at 25 μL concentration to achieve 1.9 cm zone of inhibition; higher concentrations increase antimicrobial efficacy
- 2
Against Gram-positive bacteria (S. aureus): Apply AgNPs at 25 μL concentration to achieve 2.0 cm zone of inhibition; streptomycin-equivalent antibacterial activity demonstrated
- 3
Against fungal pathogens (Aspergillus niger): Apply AgNPs at 50 μL concentration to achieve 2.6 cm zone of inhibition compared to 1.5 cm for untreated leaf extract alone
- 4
Use agar well diffusion method for testing: Spread 0.5 mL bacterial culture on nutrient agar, punch 4 wells with borer, add 10-50 μL AgNP concentrations, incubate at 37°C for bacteria or 25°C for fungi for 4-5 days
- 5
For field application: Prepare nanosuspension at 0.1 mM concentration, apply as foliar spray or soil drench at 25-200 μL per plant depending on size and infection severity
How to Prevent It
For agricultural applications, apply AgNPs as preventive treatment before pathogen exposure. Maintain proper concentration (25-200 μL) and incubation time (30-120 minutes) for optimal antimicrobial efficacy.
