Adhesion levels of Lactobacillus brevis IOEB 9809 to epithelial intestinal cells line. Adhesion levels of L. brevis IOEB 9809, harvested at mid-exponential phase, to Caco-2 cells were measured after exposure in DMEM medium supplemented or not, with tyrosine, agmatine or both. Percentage of adhesion was normalized by using unwashed wells as control and compared with adhesion levels of probiotic strains L. acidophilus La-5 and B. animalis subsp. lactis BB-12. Each experiment was performed in triplicate. Vertical bars represent the standard deviation.
