OBN potentiates the gentamycin (GEN) uptake. The GEN (1 μg/mL) treated S. aureus ATCC29213 cells were incubated in the absence (control) or presence of OBN (2 mg/mL) and measured extracellular GEN concentration. a Mid-log phase active cells used in the absence or presence of crude membrane (CE) with OBN. Two-tailed Student t test was performed for statistical analysis. P values of (*P ≤ 0.05) are considered as significant. P values of control vs OBN: 0.032, OBN vs OBN + CE: 0.026. b Starved cells re-energized with 10 mM glucose (Glu) used in the presence and absence of crude membrane (CE). Statistical analysis was performed via the two-tailed Student t test. P values of (**P ≤ 0.01) are considered as significant. Detailed “P” values are control vs OBN + Glu: 0.0073, OBN vs OBN + Glu: 0.0072, OBN + Glu vs OBN + Glu + CE: 0.0065
