| English abstract | The aim of this study was to evaluate the probiotic properties of Pediococcus acidilactici B14 and to study its resistance in the gastrointestinal system when combined with Lactobacillus acidophilus ATCC 4356 and used in a potentially symbiotic aerated soy based dessert. P. acidilactici B14 showed some important probiotic characteristics such as survival rate of 45.9% at pH 2.5; 72.4% in 0.3% bile salts and 95.8% after gastrointestinal transit at pH 4.0. Tolerance against the antibiotics cephalexin, neomycin, vancomycin, cefotaxime and penicillin G was also observed. The strain inhibited antagonism against the following cultures: Escherichia coli ATCC 25922, Bacillus cereus ATCC 33018, Staphylococcus aureus ATCC 6538P and Salmonella sp. The mixed culture of P. acidilactici B14 with L. acidophilus ATCC 4356 showed a survival rate of 92.4% after the passage through the gastrointestinal system at pH 4.0. Furthermore, in the presence of the food matrix, an average increase in cell viability, after being subjected to the gastrointestinal system of 9.9% at pH 2.0 and 6.1% at pH 4.0, was observed. This characterized the adequacy of the associated culture as probiotic in the development of a functional food such as soy based aerated symbiotic dessert |
