Untreated controls were used as a gauge of when sufficient growth was achieved. All experiments were sampled in triplicate.
  • Each PDA plate was qualitatively evaluated for the number of plugs that resulted in regrowth on a scale of 0 to 6, with "0" indicating a low level of activity, and "6" indicating a high level of activity.
