چکیده مقاله:
Recently, the increasing negative reactions of consumers to chemical compounds and the use of antibiotics in agriculture has led to pressure for the development of alternative compounds as antimicrobial agents. Plant-based antimicrobials can be a good alternative, but they have limitations and may be lost during food processing. Therefore, the formulation of these Plant-based antimicrobials in the form of nanoparticles can solve these problems. Green synthesized silver nanoparticles (AgNPs) using plant extracts are a highly active antimicrobial agent in the food industry. In the present study, green synthesized silver nanoparticles using Dracocephalum kotschyi Boiss leaf aqueous extract (AgNPs-Dk) were applied as a novel antibacterial agent against a foodborne pathogen, i.e. multidrug-resistant (MDR) Pseudomonas aeruginosa as a gram-negative model strain. According to the obtained results, the maximum zone of inhibition was ۱۳ mm and the minimal inhibitory concentration (MIC) of biogenic AgNPs-Dk was ۳۱.۲۵ μg/mL against MDR P. aeruginosa. Therefore, the biogenic AgNPs-Dk can be used as a new antibacterial agent in various fields, particularly in the food industry, such as food packaging and processing to remove foodborne pathogenicity.
