FIG. 1.

Transport of CA by L. salivarius subsp. salicinius JCM 1044 (A) and L. acidophilus JCM 1028 (B) in the presence of ionophores. De-energized, washed cells were incubated at pH 7.0 with [¹⁴C]CA in the absence (■) and presence (●) of glucose and after the addition of valinomycin (Val; ▵) or nigericin (Nig; ▿). Ionophores were added 5 min (A) or 7 min (B) after the first glucose addition (1st Glc). A second addition of glucose (2nd Glc; ○) was performed 15 min (A) or 25 min (B) after the first addition of glucose. CA* denotes both cholic acid and cholate anion.
