Anti-phage activity of Petamcin-A (PA) and 12 % acetic acid (AC) and their 200 μl ml⁻¹ concentrations against T4 phage of E. coli C-T4 after 90 min exposure time. Saline solution was used as a negative control. Concentrations of PFU of T4 phage of E. coli C-T4 were illustrated with Log10 values. Mean values with standard deviations are presented, p ≤ 0.005.
