Non-lethal cholate/deoxycholate (CA/DCA) exposure delays exponential growth phase entry without the induction of a stress response. (a) Growth curves for three Lactobacillus strains were determined after 30 s pre-exposure to 0.08% CA/DCA. CA/DCA pre-exposure delays growth of Lactobacilli initially during recovery, but all three Lactobacilli reached the stationary phase comparable to the untreated control. (b) The 24 h exposure to 0.08% CA/DCA does not increase biofilm formation. (c) L. acidophilus hydrophobicity remained high while L. plantarum and L. fermentum increased after CA/DCA exposure. **** p < 0.0001.
