Inhibitory effect of the oils on the production of violacein by C. violaceum ATCC 12472 at sub-MIC concentrations (mg/mL) of azithromycin at 0.25–0.031 mg/mL (MIC to 1/8 MIC), cinnamaldehyde at 3.75–0.47 mg/mL (MIC to 1/8 MIC) and both oils (AGSUN 5102 CLP and AGSUN 5106 CLP) at 91.8–11.48 mg/mL (MIC to 1/8 MIC). Letters/symbols represent statistical differences at p-value ≤ 0.05.
