Nutrition. Jul-Aug 2014;30(7-8):936-8. doi: 10.1016/j.nut.2013.12.009. Epub 2013 Dec 15.


Objective: The aim of this study was to evaluate the performance of the overall antioxidant of Lactobacillus fermentum LF31 bacterium with prebiotic supplement in human colon cultured cells.

Methods: The antioxidant capability of L. fermentum LF31 has been assayed in vitro on human colon adenocarcinoma HT-29 cell line using the oxygen radical absorbance capacity method.

Results: The analysis revealed that the interaction of probiotic strain cells supplemented with a prebiotic exerts a remarkable antioxidant capacity.

Conclusion: The L. fermentum used in the present study exhibited significant in vitro antioxidant capacity, increasing the total antioxidant potential.

Keywords: Antioxidative capacity; Cell culture; ORAC; Probiotic.
