Presence of 260 nm absorbing material in the supernatants ARSA treated with Ampicillin, SSE, either alone or in combination. Amp (256), ampicillin at 256 μg/ml; SSE (2), Stephania suberosa extract at 2 mg/ml; Amp (0.11 + 1.5) + SSE (1.5) = Ampicillin 0.11 μg/ml plus SSE 1.5 mg/ml; NIS (8), Nisin at 8 μg/ml was used as a positive control and untreated cells were used as negative control. The mean ± SEM for three replicates are illustrated. Means sharing the same superscript are not significantly different from each other (Tukey's HSD, p < 0.01).
