Table 3.

Bioactivity (bacteriostatic and bactericidal activity) of essential oil of outcrossed (OP) and inbred (IP) Lepechinia floribunda plants against two bacterial strains: Staphylococcus aureus and Escherichia coli.

Pollination treatment	Bacterial strains	MIC (µL/mL) bacteriostatic activity	MBC (µL/mL) bactericidal activity
OP	Staphylococcus aureus	0.44 ± 0.12	1 ± 0.00
IP	Staphylococcus aureus	0.70 ± 0.27	1 ± 0.00
OP	Escherichia coli	2.5 ± 1.73	12 ± 4.62
IP	Escherichia coli	2.5 ± 1.73	12 ± 4.62

MIC minimal inhibitory concentration, MBC minimal bactericidal concentration. Values are mean ± (SD), N = 4 (4 microplates for MIC and 4 agar plates for MBC respectively, per pollination treatment and bacterial species).
