Long-term treatment with Lactobacillus culture supernatant (CS) stimulates SMCT1 function. Postconfluent IEC-6 cells were treated with CS (diluted 1:50 in DMEM) of L. acidophilus (LA), L. rhamnosus (LR), L. plantarum (LP), and L. casei (LC) for 24 h, and Na+-dependent 14C-butyrate uptake was measured. Values are means ± SE; n = 3. *Different from control, P < 0.001.
