For the median effective 2-phenylethanol concentration (EC50) experiment, this was determined as described in [29]. Mycelial plugs (6 mm diameter) of 3-day-old colonies were placed at the center of PDA media containing 2-phenylethanol (0, 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 1.0, or 1.2 mg/mL). After incubating in darkness at 25 °C for 3 days, the diameter of the colonies was recorded. Each treatment was repeated three times. The growth inhibition rate (%) was calculated using the following formula:
EC50 was calculated using SPSS software version 26.0.
