Thermal and pH stability test of phage LPSent1. (A) Thermal stability of LPSent1. (B) pH stability of LPSent1. Temperature stability tests were performed at 40, 50, 60, 70, and 80°C for 30 min or 60 min at pH 7, the control temperature was set at 30°C for 30 min or 60 min. pH experiments were performed at pH range 2-13 for 24 h at 37°C, pH 7 represented the control value around which the deviations were measured. The data (n = 3) displayed the percentages of the residual phages after each treatment, as normalized from the control ± standard error and were analyzed by Student’s t-test; *indicates significantly different from the controls, p ≤ 0.05.
