Production of the bacteriocins enterocin A and enterocin B in
Enterococcus faecium CTC492 was dependent on the presence
of an extracellular peptide produced by the strain itself. This
induction factor (EntF) was purified, and amino acid sequencing
combined with DNA sequencing of the corresponding gene identified it as a peptide of 25 amino acids. The gene encodes a prepeptide of 41 amino
acids, including a 16-amino-acid leader peptide of the double-glycine
type. Environmental factors influenced the level of bacteriocin
production in E. faecium CTC492. The optimal pH for
bacteriocin production was 6.2. At pH 5.5, growth was slow, and very
little bacteriocin was formed. The presence of NaCl or ethanol (EtOH)
was also inhibitory to bacteriocin production, and at high
concentrations of these solutes, no bacteriocin production was
observed. The induction factor induced its own synthesis, and by
dilution of the culture 106 times or more, nonproducing
cultures were obtained. Bacteriocin production was induced in these
cultures by addition of EntF. The response was linear, and low
bacteriocin production could be induced by about 10
17 M
EntF. This response was attenuated by low pH or the presence of high
concentrations of NaCl or EtOH, and 300 times more EntF was needed to
induce detectable bacteriocin production in the presence of 6.5% NaCl.
High levels of bacteriocin production in cultures grown at low pH or in
the presence of high concentrations of NaCl or EtOH were obtained by
addition of sufficient amounts of EntF.
