The following bacterial species were used: Bacillus subtilis (ATCC 10707), Enterobacter cloacae (human isolate), Escherichia coli (ATCC 0157:H7), Micrococcus flavus (ATCC 9341),Proteus mirabilis (human isolate), Pseudomonas aeruginosa (ATCC 27853), Salmonella enteritidis (ATCC 13076), S. epidermidis (ATCC 12228) S. typhimurium (ATCC 13311) Staphylococcus aureus (ATCC 25923). The antibacterial assays were carried out by the disc-diffusion [25 (link)] and microdilution method [26 ,27 (link),28 (link)] in order to determine the antibacterial activity of oils and their components against the human pathogenic bacteria. The bacterial suspensions were adjusted with sterile saline to a concentration of 1.0 × 105 CFU/mL. The inocula were prepared daily and stored at +4 °C until use. Dilutions of the inocula were cultured on solid medium to verify the absence of contamination and to check the validity of the inoculum.
