In previous studies (Garcia, Oliveira, Queiroga, Machado, & Souza,
2012; Oliveira, Garcia, Queiroga, & Souza, 2012) we demonstrated that
Lactobacillus acidophilus (LA-5), Lactobacillus casei subsp. paracasei
(L. casei-01) and Bifidobacterium lactis (BB-12) remained viable in goat
coalho cheese during 21 days of cold storage, and the viable counts
were always higher than those recommended (6–7 log cfu/g) for a probiotic
food. Moreover, the incorporation of the tested probiotic bacteria
in the production of coalho cheesewas shown to be feasible because the
probiotic bacteria did not cause changes in the quality characteristics of
the product, except for improving its sensory attributes. In this manuscript,
we report further investigations of the survival of these probiotic
bacteria when added to goat coalho cheese and exposed to experimental
conditions that are typically encountered throughout the gastrointestinal
tract; and of the inhibitory effect of these probiotic strains
against the pathogenic bacteria Staphylococcus aureus and Listeria
monocytogenes in goat coalho cheese throughout the storage.
