Evaluation of Antimicrobial Efficacy of Photogenic Iron Nanoparticles Against Xanthomonas campestris

Abstract

This study investigates the antimicrobial efficacy of photogenic iron nanoparticles (FeNPs) against Xanthomonas campestris, a notorious plant pathogen causing bacterial spot disease in various crops. The synthesis of FeNPs was achieved through a facile and eco-friendly green synthesis approach, utilizing a plant extract as a reducing and capping agent. The resulting photogenic FeNPs were characterized using various analytical techniques, confirming their size, morphology, and composition. The antimicrobial activity of the synthesized FeNPs was assessed through in vitro experiments against X. campestris. The inhibition zones and minimum inhibitory concentration (MIC) were determined, showcasing the potential of these photogenic nanoparticles as effective antimicrobial agents. Further investigation into the mode of action revealed disruption of the bacterial cell membrane integrity, leading to compromised cellular functions and eventual cell death.

Photoluminescence studies demonstrated the unique photogenic properties of the FeNPs, suggesting potential applications in imaging and tracking. Additionally, the biocompatibility of the FeNPs was evaluated using plant model systems, affirming their low toxicity and potential for sustainable agricultural practices. Furthermore, the study explored the stability of the FeNPs under various environmental conditions, highlighting their robustness for potential field applications. The findings suggest that photogenic FeNPs could be harnessed as a promising alternative to traditional antimicrobial agents for controlling X. campestris infections in crops.

In conclusion, this research contributes to the understanding of the antimicrobial properties of photogenic FeNPs against X. campestris, providing insights into their potential applications in agriculture. The eco-friendly synthesis, coupled with the nanoparticles' unique photoluminescent properties, makes them an attractive candidate for sustainable and effective disease management strategies in the agricultural sector. Further field trials and optimization studies are warranted to translate these promising laboratory results into practical applications for crop protection.
