Biological characteristics of phage swi3. (A) One-step growth curve, (B) pH stability, and (C) thermal stability. Data are expressed as means. At the optimal multiplicity of infection of 1, the one-step growth analysis of swi3 showed a 25-min latent period with a burst size of 25-plaque-forming units (PFU)/infected cell. Phage swi3 remained stable both at pH 6.0–8.0 and less than 50°C for at least 1 h.
