Özet

In this study, five strains of Leuconostoc pseudomesenteroides were thought to have probiotic properties and anticancer activity isolated from natural pickles and identified by performing the 16S rRNA sequence analysis. The probiotic properties, postbiotic amounts, the capacity to adhere to the L-929, HT-29 and Caco-2 cell lines, the effects of postbiotic and bacterial extracts on cell viability and biochemical activities were investigated in the strains. In the results, Leu. pseudomesenteroides Y6 strain was detected to have the best resistance to the stomach and intestinal environments, and the quantities of postbiotic metabolites are similar to each other. The bacterial adhesion capacities were found to be in the range of 1.66–8.5%. Furthermore, postbiotic metabolites of all isolates had good anticancer activity (27.67–86.05%) and the activity of bacterial extractions increased depending on concentration. Leu. pseudomesenteroides Y4 and Y6 strains generally showed better activity than controls and all strains were strong 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavengers in the antioxidant studies. In conclusion, the Y6 strain, which had the best probiotic feature, was found to show significantly good biological activity. It is thought that this isolate will be supported by new in vivo studies and eventually be brought to the food and health industry.
