During subsequent storage at 22 or 4 °C for 7 days using as a carrier
peptone/saline or distilled water the population of L. monocytogenes
Scott A was further reduced under the detection limit in both olive cultivars whereas
the population of E. coli O157 EDL-932 could be detected
only in olives stored in peptone/saline at 22 °C for 7 days indicating a
protective effect of the above suspension medium(Table 5). Alkali treated
green table olives cv. Chalkidiki fermented by L. pentosus (pH 4.2 and
6% NaCl in the final product) when stored at 20 °C in a new brine containing
6% NaCl and 7 log CFU/ml E. coli O157:H7 or L. monocytogenes
showed a reduction of the inoculated foodborne population under the
detection limit of the enumerationmethod after 5 or 9 days, respectively
(Argyri et al., 2013).
