Cytotoxicity assay of E. lactis 10NA and E. lactis 50NA strains’ supernatants on Caco-2 cells. Survivability percent of Caco-2 cells relative to control in the bacterial culture supernatants with different concentrations (100% (v/v), 50% (v/v), 10% (v/v), and 5% (v/v)). The control used is sterile MRS broth with the same concentrations as the tested supernatants. The values are presented as the mean ± SD of three replicates
