The isolate exhibited high tolerance to acidic conditions (Table 1). The resistance of the isolate was observed after exposition
to acidified media, except for pH 2, where the presence of colonies was only observed in the initial time (>7 log CFU/ml). In the other treatments, pH 3 and pH 4, no significant differences were observed when the samples were compared to the control (pH 7) during the incubation time, ranging between 0 and 4 h.
