Figure 3. Susceptibility of the original strains used in the blend to phages present in the supernatants at different time points (after 6.6, 139, 272, 405 and 538 generations) of the propagation experiment. Blends were sequentially propagated in milk for up to 538 generations. Replicates A-1 and A-2 were used as control where no phage cocktail was added. Replicates B-1 and B-2 were challenged at the onset of the experiment with a cocktail of lactococcal phages ϕTIFN1, ϕTIFN5 and ϕTIFN7.
