The anti-Legionella activity of the concentrated supernatant for each strain grown in LB medium is the mean of three independent experiments.
-: no activity.
+: zone of inhibition with a diameter < 4 mm.
++: zone of inhibition with a diameter between 4 and 8 mm.
+++: zone of inhibition with a diameter > 8 mm.
