title: Antioxidative capacity of Lactobacillus fermentum LF31 evaluated in vitro by oxygen radical absorbance capacity assay.
abstract: 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.
  
  
  CONCLUSIONS
  The L. fermentum used in the present study exhibited significant in vitro antioxidant capacity, increasing the total antioxidant potential.
