Biological characteristics of the phage vB_SalP_LDW16. A MOI of the phage vB_SalP_LDW16. Phage titers were measured at different MOIs. B One-step growth curve of the phage vB_SalP_LDW16. The titer of the phage vB_SalP_LDW16 was determined every 10 min. C The thermal stability of the phage vB_SalP_LDW16. The phages were cultured in a water bath at different temperatures. **p < 0.01, ***p < 0.001 versus samples at 40 ℃ under the same incubation time, ^###p < 0.001 versus sample at 20 min at the same incubation temperature. D The pH stability of the phage vB_SalP_LDW16. The phages were incubated in different acid–base environments for 1 h. A, B, C, D The phage titers were determined using the double-layer agar method and each data point represented the mean values ± standard deviations (SD) from at least three replicate experiments
