Violin plots of the thermal and pH stability of phage ZCKP2. The phage stability is represented as enumerated titer (log10 of PFU/mL). A. Thermal stability: phage titer at -20 °C was compared to other temperatures’ phage titers. B. pH stability: phage titer at pH 7.0 was compared to phage titers at the other pH values. The mean of phage titer triplicates was calculated, and statistically analyzed by t-test at a significance level of P < 0.05.
