Fig. (4) Antagonistic assay against different bacterial strains by the 10X concentrated 24-DSM supernatants; as a representative samples A: Escherichia coli 6633, B: Corynebacterium diphtheria 51696. Bacterial strains suspension (100 µl of OD₆₀₀ ~1.0) were spread on MHB agar medium, after drying, 10 µl of 10X concentrated 24-DSM supernatants were loaded in 4mm in diameters well (R1, R2 and R3), 10 µl of 12.5 mg/ml of chloramphenicol was used as positive control (Cm) and 10 µl of 10X desalted medium was used as a negative control (-ve).
