Acoustic Emission Signal of Lactococcus lactis before and after Inhibition with NaN₃ and Infection with Bacteriophage c2

Table 3

Summary of AE peaks (in minutes) detected during the infection of L. lactis with Bacteriophage c2 with 10⁹ pfu/mL at 32°C. The 1st AE cycle, 2nd AE cycle, and 3rd AE cycle labeling represent proposed primary, secondary, and tertiary sequences of phage-related AE signals.
