At five time points over a time period of 3 hours, CFU counts increased dramatically in inoculated milk samples following the addition of enzyme storage buffer [
], Ply187AN [
], and LysK [
]. However, following the addition of Ply187AN-KSH3b [✖], the CFU counts were reduced to, and stayed, at 0% of the enzyme storage buffer control at time point zero, indicating effective killing. Error bars = SEM.
