  1. MIC and MLC are reported in mg/mL. For all strains shown, n = 3.
  2. aMinimum inhibitory concentration (MIC) is the lowest concentration of oil-infused agar on which no growth occurred.
  3. bMinimum lethal concentration (MLC) is the concentration of oil-infused agar from which no growth occurred after transfer to fresh agar without essential oil.
  4. cDenotes resistance to penicillin, tetracycline, kanamycin, and chloramphenicol.
  5. dNot done; due to the extremely fastidious growth requirements of this strain, sufficient growth was not obtained to determine the MIC and MLC for these oils.
