(A) Thermal stability of MIJ3: the phage was incubated in LB medium at different temperatures for 60 min. The phages survived at temperatures of 40, 50, and 60°C. At 70°C, phage concentration showed a 4-log drop. MIJ3 was not able to survive at 80, 90, and 100°C. Error bars represent SEM for three replicates. (B) pH stability of MIJ3. The phage is highly stable at pH values from 3 to 10; however, no survival was observed when phages at a pH of 2 and 1.
