Fig. 1. Tolerance of the E. durans LAB18s to bile salts concentration, containing 0.1% of
bile salts (B); 0.25% (;); 0.5% (6); 1.0% (-); and 1.5% (,) after 4 h of incubation at
37 C without shaking. The pH 7.0 without bile salts was used as a control (C). Each
point represents the mean s.e.m. of three independent experiments.
