Phage stability at different temperatures and pH values. (a) Phage titers on a logarithmic scale of plaque-forming units/mL (log PFU/mL) after 1 h of incubation at temperatures ranging from 25 °C to 60 °C. (b) Phage titers in log PFU/mL after 1 h of incubation at 37 °C at pH values ranging from 2 to 12. Error bars represent the standard deviation.
