In this study we investigated the specific growth rate () and the generation time (t) of two Lactobacillus salivarius strains isolated from dental root canal and two probiotic Lactobacillus strains by intestinal origin. Differences between values of both parameters were observed, depends to the strains and pH values. All Lactobacillus investigated strains presented higher values of specific growth rate () and smaller of generation time (t) at pH 7.0 than pH 8.0. Lactobacillus salivarius strains G1 and G2 isolated from dental root canal had biger values of specific growth rate () at both pH values than probiotic Lactobacillus strains. Between the specific growth rate () and the generation time (t )there is a close negative correlation. Pearson coefficient was -0,95.
