Effects CPS on the bacterial resistance to bile salts and acid. a Survival rate of B. longum 105-A (white) and B. longum 105-A ∆cpsD (black) in MRS broth, which is adjusted to indicated pH. b Adaptation by low pH. Cells were pre-incubated at 37 °C, for 2 h in MRS (pH 6.5; white) or pH 4.5 (black), then transferred to the same medium but pH 3.5 incubate for 2 h. B. longum 105-A (left) and B. longum 105-A ∆cpsD (right). c Survival rate of B. longum 105-A (white) and B. longum 105-A ∆cpsD (black) in MRS broth contained bile acid, 0–0.3% (w/v)
