Antimicrobial activity of culture (C), pellet (P) and supernatant (S) spot of LAB on A. baumannii A118 at 16 h incubation. Inhibition halos diameter (IHD) were measured, and inhibitory capacity was interpreted > 20 mm = High (H), 20–10 mm = Intermediate (I) and < 10 mm = Low (L). The width of the clear zone (R) is the difference between IHD and spot diameter divided by two (SD), inhibitory capacity was interpreted as R > 6 mm = High (H), 5–2 mm = Low (L), < 2 mm = Without Inhibition (WI). The arbitrary units per ml (AU/ml) was calculated as the IHD × 1000 divided by the μl seed (Halder et al.5). The average of three independent assays is represented on the table.
