these microorganisms must be capable of
tolerating stressful conditions such as acidity, temperature, salt
stress and freeze-drying. To tolerate NaCl, various mechanisms
developed by LAB are described, for example the uptake or synthesis
of a limited number of solutes (Bremer & Kr€amer, 2000).
To separate the LAB isolates in this study according to their
overall characteristics, PCA was carried out based on probiotic
characteristics (Fig. 1). The first seven components accounted for
71.44% of the total variance. Among them, PC1 and PC2 made up
16.26 and 12.702% of the total variance respectively. Probiotic
