Antiproliferative effect of PM produced by Lactobacillus plantarum RG14 on HT-29 cells determined via trypan blue staining and cell count. Cell population equals to the viable cell concentration of a single well multiplied with 100 μl of complete growth media used to suspend the cell pellet. Values within the same row and experiment having an asterisk indicate significant difference (P < 0.05) from the untreated control groups. Error bars represent the standard error of the mean
