broth below 4 after 8 h of incubation. After 24 h, Lb. pentosus ES124,
Lb. fermentum ES137 and Lb. fermentum ES148 showed the lowest
pH values reaching 3.30, 3.23 and 3.27, respectively (Fig. 1). This
rapid acidification potential is important in the elaboration of fermented
foods were lower pH values are desired not only for
organoleptic properties but also in order to prevent the growth of
pathogenic microorganisms.
