Effects of secretion metabolites of different bifidobacteria species containing indicated concentrations of dried materials from the methanolic extract on the viability of HT-29, Caco-2 cancer cell lines, and KDR/293 normal cells for 48 h incubation by MTT assay test. Untreated cells and methanolic extract of MRS media were used as negative control, and 5-FU (7 µL/well of 96-well plate) was used as positive control. Data are expressed as mean viability ± S.D. Asterisks signify statistically significant differences (*P ≤ 0.05, **P ≤ 0.01)
