Keys: Sa = Staphylococcus aureus; Bc = Bacillus cereus; Ec = Escherichia coli; Lm = Listeria monocytogenes; Se = Salmonella enterica; Pa = Pseudomonas aeruginosa; CN = gentamicin (10 μg/disc) as a positive control; EA = ethylene acetate (10 μl/disc) as a negative control; ND = not detected. Data are average of triplicates; numbers followed by the same letter superscripts in the same row do not vary significantly by Duncan’s multiple range test at ; SE: standard error.
