Bacterial Strains	EOs (mg/mL)					SEM	p Value
Bacterial Strains	GEO	SEO	BEO	LEO	DLEO	SEM	p Value
E. coli	10.67	11.33	12.67	14.33	12.33	0.84	0.09
Salmonella	12.33	11.33	11.33	12.33	11.00	0.60	0.41

Zone of growth inhibition values are expressed as the mean of at least three experiments in mm, including a disc diameter of 6.0 mm. According to ANOVA and Turkey test, different superscript letters in the same column showed differences (P < 0.05). GEO: grapefruit essential oil, SEO: sweet orange essential oil, BEO: bergamot essential oil, LEO: lemon essential oil, DLEO: d-limonene essential oil. SEM: standard error of measurement.
