Biological properties of S. marcescens phage SMP. A One-step growth curve of phage SMP. Phage SMP has a short latent period. The phage titer increased rapidly and stabilized at 100 min. B The effect of pH on the stability of phage SMP was determined at different pH values ranging from 3 to 11 at 37 °C for 2 h. C Effect of temperature on phage SMP stability was determined at −80 °C, 4 °C, 25 °C, 37 °C, 50 °C, 60 °C, 70 °C, and 80 °C for 1 h. Values are the means  ±  standard deviations from triplicates of each treatment
