The results exhibited that with application of PEO, biofilm formation of both Listeria monocytogenes and Proteus mirabilis was inhibited by 45.80% and 73.01%, respectively in contrast to their respective controls. Listeria monocytogenes and Proteus mirabilis as positive control. Antibiofilm activity (%) was also performed against pure cultures of two pathogens i.e. The oil was found to be more effective against Pseudomonas aeruginosa and Salmonella enterica serovar Typhi.

Maximum zone size was observed for Proteus mirabilis whereas, MIC values ranged from 5000-20000 ppm for all tested organisms. Proteus mirabilis, Salmonella enterica serovar Typhi, Klebsiella pneumonia, Shigella flexneri, Escherichia coli and Pseudomonas aeruginosa whereas antioxidant assay was measured using 1, 1 diphenyl-2 picrylhydrazyl (DPPH) and 2-2-azinobis-3 ethylbenthiazoline-6-sulphonic acid (ABTS) radical scavenging activity. Listeria monocytogenes, Enterococcus faecalis, Bacillus cereus and Staphylococcus aureus and six Gram-negative viz. Antimicrobial activity was measured by using zone inhibition assay (ZOI) and Minimum Inhibitory Concentration (MIC) against ten food borne pathogens including four Gram-positive viz. The current study was carried out to examine in-vitro antimicrobial, antioxidant and antibiofilm efficacy of Peppermint essential oil (PEO) for its potential application in meat products. *Corresponding author: N Mehta E-mail: published on 28 May, 2020.
