E. faecium ES216 also inhibited Lb. plantarum and E. mundtii
ES198, another bacteriocin producer. This wider spectra of action
suggests that ES216 could produce a different type of bacteriocin
that the others or that it could produce more than one bacteriocin.
P. pentosaceus ES51 has shown to be a highly sensitive indicator
strain to bacteriocins.
The amount of bacteriocin produced was 1 105 and 2 105
UA/mL depending on the producer strain L. innocua was used as
indicator microorganism (Table 3). The identification of bacteriocin
producing strains is important to elaborate safer foods where
