Effect of L. fermentum MBC2 on PEPT-1 mutant strain and analysis of aging biomarkers. (A) Kaplan-Meier survival plot of PEPT-1 worms fed L. fermentum MBC2. Lifespans of OP50- and LGG-fed animals are reported as controls; n = 60 for each data point of single experiments. (B) Analysis of autofluorescence of lipofuscin in PEPT-1 worms fed OP50 (a), LGG (b) and L. fermentum MBC2 (c) at day 13. Ten worms were used for each measurement. Scale bar = 100 μm. (C) Measurement of ROS levels in L. fermentum MBC2-, LGG- and OP50-fed PEPT-1 mutants at 1 day of adulthood. Statistical analysis was evaluated by one-way ANOVA with the Bonferroni post-test; asterisks indicate significant differences (** p <0.01; *** p <0.001). Bars represent the mean of three independent experiments.
